Game lovers Portal 2 sooner or later they face various kinds of problems. Among the most frequently encountered problems are when Portal 2 does not install, does not start, or freezes, slows down, or a black screen appears, and other problems arise during the game, in particular, Portal 2 does not save, controls do not work, or there is no sound in game, in this article we will look in detail at the main causes of problems and errors, as well as ways to eliminate them.
Portal 2 won't install
Portal 2 System Requirements
Before installing Portal 2 on your computer, you should check the system requirements provided by the game developers. Remember that for the game to work correctly, at least the minimum requirements must be met. However, in some cases, even minimal settings may not be enough. In this case, you will either have to abandon the game or increase the performance of your computer.
| Minimum | Featured | |
| OS: | Windows XP/Vista/7 | Windows XP/Vista/7 |
| CPU: | Intel Pentium 4 3.00 GHz AMD Athlon 64 3200+ |
Intel Core 2 Duo 2.50 GHz AMD Athlon 64 X2 5400+ |
| Video card: |
nVidia GeForce 7600 128 Mb |
nVidia GeForce GTX 280 1 Gb |
| RAM: | 1 Gb | 2 Gb |
| Free disk space: | 8 Gb | 10 Gb |
| Download DirectX | ||
Of course, we won’t throw away the game, but we will work on the preliminary settings. In this regard, we will check our PC for compliance with the simplest requirements. So if Portal 2 won't install, let's see if there is enough free space on your hard drive to install the game. The distribution requires free disk space, so a few gigabytes of extra space will not hurt. Also, it should be kept in mind that various games require a significant amount of free space, up to 100 GB and above.
Portal 2 installation is blocked by antivirus program
Often, antivirus programs, in the fight against viruses, protecting our computer from external threats, for security purposes they block numerous processes running operating system. Sometimes such security is so strong that it begins to block access not only to viruses, but also to suspend some normal processes, perhaps by mistake, considering them potentially vulnerable. Hence the conclusion: disable your antivirus while installing Portal 2.
Cleaning your computer and rebooting
Sometimes, a simple system reboot can immediately solve many problems that arise both during the installation of games and their subsequent operation. The same applies to various programs and applications. There are many reasons, as already mentioned: the computer is filled with various kinds of garbage, including an overflow of the system cache, the maximum permissible number of simultaneously running processes, among which, perhaps, some are frozen and are not running, but the load on the system is not bad at all. In this case, .
Internet access
During the installation process, some game clients require access to the Internet, providing access to the installation or update server. In this case, it is necessary make sure the Internet is working.
Portal 2 won't launch
Before you look for reasons why Portal 2 won't launch, you need to make sure that the installation of the game itself was successful. Otherwise, if during the installation process on the computer any failures or errors were observed, but at the same time the game was installed, it is still impossible to guarantee the subsequent launch and operation of the game with maximum accuracy. If the game starts, you're lucky. However, what will happen next is unknown.
Reinstalling the game
Surely, many gamers have encountered a situation or, as you might call it, a cause or effect associated with reinstalling a game. That is, if the game installed normally, but does not want to start, reinstalling it can fix the problem. It is unknown what this is connected with, perhaps the antivirus or firewall “ate” some files or something else during installation, but after installing the game again, it becomes fully functional. Thus, delete the game and install it again, paying attention to every detail of the installation. Perhaps at some point the installation program will ask for some files, etc.
Searching for information by error text
Another option, it is not described in this article, but as a little secret that everyone knows about, we will add that an error when starting Portal 2 is usually accompanied by a corresponding system message. So, in this case, it would be true enter the text of such an error in the search, as a result of which you will receive the most detailed answer, and, moreover, concerning this specific error. This is how you will accurately determine the cause and, as a result, find a solution.

Run Portal 2 as administrator
As an alternative, you can run the game as an administrator. That is, in our case, so that run Portal 2 as administrator, you must press right click mouse on the game shortcut and select Run as administrator. If this method helps solve the problem so that the error does not occur later, set run as administrator by default for this game. To do this, open the Shortcut Properties, in the Compatibility tab, check the box Run this program as administrator.
Game compatibility issue
Another obstacle to launching Portal 2 may be the game's incompatibility with your operating system. In this case, still there, in the Shortcut Properties, you need to add a checkbox Run the program in compatibility mode for:, and select the desired OS from the drop-down list.
Availability of .NET Framework libraries
Also, a very serious problem with launching Portal 2 is the lack of the .NET Framework library installed on the computer, which ensures the launch and maintains the functionality of almost all programs and applications, including games. This is a prerequisite and Microsoft .NET Framework must be installed. At the same time, you should keep in mind that there are different versions of the .NET Framework library, and therefore the presence of one of them on your computer cannot sufficiently guarantee the correct operation of the game.
Availability of DirectX
And, of course, perhaps the most important condition, a requirement that is necessary for absolutely all games, including Portal 2, installed DirectX. Without it, no game will work. Currently, almost all distributions that in one way or another require DirectX installed already include this set. Typically, DirectX is automatically installed with the game. However, if it is missing, you need to download and install it. It is not necessary to do this before installing the game, you can do it after installation, but installing DirectX on your computer is a must.
Portal 2 freezes
Video card problem in Portal 2
The reason many computer games freeze, including Portal 2, is the video card, its incompatibility minimum requirements. For gamers, the video card is the main tool, the main success or disappointment. If your weak video card, then no updates, no drivers, and the like will help you. To achieve maximum effect and enjoy the game, A reasonable remedy would be to think about purchasing a more modern, stronger video card. The downside of this method can be a significant financial investment, since high-quality graphics and gaming at maximum settings are not a cheap pleasure, and buying a good video card can cost a pretty penny.
Installing and updating the video card driver
But don't despair. In order for the game to run more or less well on the computer, you can solve the problem even with a regular average video card; you can configure it, and also check all the necessary computer parameters to ensure a comfortable game. If your video card is more or less modern, then It is mandatory to have the latest drivers. Fortunately, you can download and install them completely free of charge from the manufacturer’s official website. After installing the drivers, as a rule, if you have an AMD or nVidia video card, then special software is downloaded along with them, which is installed on the computer, and thanks to which you can control various game settings.
Portal 2 slows down
Let's return to the problems described above, related, so to speak, to poor installation of the game. If there were any problems, it is quite possible that the game will often cause slowdowns, lags and other errors in the future.
Portal 2 slows down due to unnecessary processes
If the game Portal 2 slows down, you can also check the operating system load. Any game itself requires significant resources to play and work correctly. Portal 2 is no exception. If at the moment, in addition to the game, other processes are running on the system, you need to check them and determine how important they are at the moment. As a quick solution, close all unnecessary processes and leave only the most necessary ones. The main thing here is not to overdo it, otherwise you can close everything in the world so that the computer itself simply stops.

Portal 2 slows down due to weak internet
Another point is Internet access. If the game requires good high-speed Internet, then of course the problem is obvious and, in principle, understandable. Therefore, it is worth thinking about purchasing a more powerful tariff. But there are situations when even with good internet, Portal 2 is slow. For example, in certain moment an application on the computer has begun updating, for example, an antivirus, not to mention if movies are downloaded along with the game. Or maybe you watched a video, for example about Walkthrough of Portal 2, and played the game at the same time!? Thus, anything will slow down here. Decide one thing: either a movie or a game. And if you need both, then at a minimum the computer must have "thermonuclear" properties. Do you understand what we mean!?
Portal 2 how to increase fps
Setting up graphics in Portal 2
High fps or fps is something that is so often lacking in the game. If you are one of such users, then use of maximum graphic settings can greatly affect the FPS of the game and cause various lags, slowdowns, and freezes. On the other hand, If you lower the graphics settings as much as possible, you can significantly increase FPS. By the way, you can control graphics settings not only in the game itself, but also in the software of your video card.
Video card overclocking tools
To significantly increase fps Portal 2 Many users use overclocking tools. There are a lot of them on the Internet and finding them is not difficult. For example, to accelerate nVidia video card, you can use the MSI Afterburner utility.
Low FPS due to overheating
Low FPS in Portal 2 maybe because of CPU overheating, and the video card itself. The above remedies can eliminate this problem, thanks to which you can, for example, set the cooler speed to maximum.
Portal 2 black screen
If it happened that Portal 2 gives a black screen, there is a problem, again, with the video card. Check the availability of drivers, namely, whether they are the latest ones. If the manufacturer has produced more than new version, don’t be lazy to waste time - update your video card driver.
Portal 2 crashes
If the game Portal 2 crashes on desktop, in this case it is worth checking the correct installation of both the game itself and updates, patches, etc. Perhaps the previous update itself contains certain errors. There is little that depends on the gamer; all questions are up to the game developers. If it is possible to reinstall the received updates, do so. In the worst case, reinstall the game itself.
Portal 2 won't save
Probably the most common reason why Portal 2 won't save, is incorrect path to save game. What does it mean? This means only one thing - many games refuse to work with Cyrillic. If the folder on your computer with game saves has Cyrillic characters in its path, then perhaps Portal 2 will give an error when saving. Simply put, use the path to the Portal 2 save folder, only in Latin, without Russian words.
Most problems with saving Portal 2 occur due to the game being incompatible with the operating system. This fact is most inherent in the Windows 7 operating system, but perhaps also in others.
Portal 2 controls not working
Keyboard or joystick problem
If in Portal 2 controls not working, there are many reasons. For example, if the control buttons do not respond at all, there may be a problem with the controller or keyboard. Check the connection and, if necessary, restart the device. Sometimes, a game restart is required to complete this procedure.
Sticky keys in game
Often, problems with controlling Portal 2 can occur due to sticky keys. When several buttons are pressed simultaneously, the system reacts to this in a unique way. What conclusion can be drawn from this? - use joysticks to play.
Incorrect control settings
At the same time, the problem with the controls may lie in the control settings of Portal 2. Carefully check the control keys and, if necessary, replace them with the ones you need.
Incorrect keyboard layout
Alternatively, you can change keyboard layout. You can do this with a keyboard shortcut Shift + Alt. The fact is that For some reason, controls in some games only work on the English keyboard or vice versa. Experiment.
Portal 2 no sound
Adjusting Volume Settings
There is one interesting point: if at all, it is understandable, but there are situations when the sound on the computer works, but, for example, in some application, for example in a browser or game, there is no sound. The thing is that in the settings sound card The appropriate parameters have not been set. Simply put, if in Portal 2 no sound, necessary Open Volume Options and check all available settings, paying special attention to our game.
Setting up sound in Portal 2
If there is no such application in the volume settings, but there is still no sound in Portal 2, go to the settings of the game itself. Most likely, the main audio device has been disabled or changed somewhere. And further. Very often, and occurs in almost everyone - The game's sound settings have gone wrong or playback devices not defined. In order to solve the problem, restart the game, and if there is a desire and a little time, for greater confidence, restart the system. In many cases this method helps.
This is a little of what you can do and what to look for if you have problems with Portal 2. Perhaps something is left unsaid, something is said incorrectly. If you have any questions about the game, please ask them in the comments. Or, if you have already encountered various kinds of problems and were able to solve them, please share. Perhaps someone is having a similar problem right now, and your solution will help fix the situation. Good luck and have a good game!
Unfortunately, games have flaws: stutters, low FPS, crashes, freezes, bugs and other minor and not so minor errors. Often problems begin even before the game starts, when it does not install, does not load, or does not even download. And the computer itself sometimes does weird things, and then in Portal 2 there’s a black screen instead of a picture, the controls don’t work, you can’t hear the sound or anything else.
What to do first
- Download and run the world famous CCleaner(download via direct link) - this is a program that will clean your computer of unnecessary garbage, as a result of which the system will work faster after the first reboot;
- Update all drivers on the system using the program Driver Updater(download via direct link) - it will scan your computer and update all drivers to the latest version in 5 minutes;
- Install the program WinOptimizer(download via direct link) and enable game mode in it, which will end useless background processes while launching games and improve performance in the game.
The second thing to do if you encounter any problems with Portal 2 is to check the system requirements. In a good way, you need to do this before purchasing, so as not to regret the money spent.
Minimum system requirements for Portal 2:
Windows 2000, Intel Pentium 4, 1 Gb RAM, 7.6 Gb HDD, nVidia GeForce 7600 128 Mb
Every gamer should have at least a little understanding of components, know why a video card, processor and other things are needed in the system unit.
Files, drivers and libraries
Almost every device in a computer requires a set of special software. These are drivers, libraries and other files that ensure the correct operation of the computer.
You should start with the drivers for your video card. Modern graphics cards are manufactured by only two large companies - Nvidia and AMD. Having found out which product drives the coolers in the system unit, we go to the official website and download the latest driver package:
A prerequisite for the successful functioning of Portal 2 is the availability of the latest drivers for all devices in the system. Download the utility Driver Updater to download easily and quickly latest versions drivers and install them with one click:
If Portal 2 does not start, we recommend that you try disabling your antivirus or putting the game in antivirus exceptions, and also check compliance again system requirements and if something from your assembly does not correspond, then, if possible, improve your PC by purchasing more powerful components.
Portal 2 has a black screen, a white screen, and a color screen. Solution
Problems with screens of different colors can be divided into 2 categories.
Firstly, they often involve using two video cards at once. For example, if your motherboard has a built-in video card, but you play on a discrete one, then Portal 2 may launch for the first time on the built-in one, but you will not see the game itself, because the monitor is connected to a discrete video card.
Secondly, color screens occur when there are problems with displaying images on the screen. This can happen for various reasons. For example, Portal 2 cannot work through an outdated driver or does not support the video card. Also black/ White screen may be displayed when running at resolutions that are not supported by the game.
Portal 2 crashes. At a specific or random moment. Solution
You play for yourself, play and then - bam! - everything goes out, and now in front of you is a desktop without any hint of a game. Why is this happening? To solve the problem, you should try to figure out what the nature of the problem is.
If the departure occurs in random moment time without any pattern, then with a 99% probability we can say that this is a mistake in the game itself. In this case, it is very difficult to fix something, and the best thing to do is just put Portal 2 aside and wait for the patch.
However, if you know exactly at what moments the crash occurs, then you can continue the game, avoiding situations that provoke a crash.
However, if you know exactly at what moments the crash occurs, then you can continue the game, avoiding situations that provoke a crash. In addition, you can download the Portal 2 save and bypass the departure location.
Portal 2 freezes. The picture freezes. Solution
The situation is approximately the same as with crashes: many freezes are directly related to the game itself, or rather to the developer’s mistake when creating it. However, often a frozen picture can become a starting point for investigating the deplorable state of a video card or processor.
So if the picture in Portal 2 freezes, then use programs to display statistics on the loading of components. Perhaps your video card has long exhausted its working life or the processor is heating up to dangerous temperatures?
The easiest way to check the load and temperatures for the video card and processors is in the MSI Afterburner program. If you wish, you can even display these and many other parameters on top of the Portal 2 image.
What temperatures are dangerous? Processors and video cards have different operating temperatures. For video cards they are usually 60-80 degrees Celsius. For processors it is slightly lower - 40-70 degrees. If the processor temperature is higher, then you should check the condition of the thermal paste. It may have already dried out and needs to be replaced.
If the video card is heating up, then you should use a driver or an official utility from the manufacturer. It is necessary to increase the number of revolutions of the coolers and check whether the operating temperature decreases.
Portal 2 is slow. Low FPS. Frame rate drops. Solution
If there are slowdowns and low frame rates in Portal 2, the first thing to do is lower the graphics settings. Of course, there are many of them, so before reducing everything, it’s worth finding out exactly how certain settings affect performance.
Screen resolution. In short, this is the number of points that make up the game picture. The higher the resolution, the higher the load on the video card. However, the increase in load is insignificant, so you should reduce the screen resolution only as a last resort, when everything else no longer helps.
Texture quality. Typically, this setting determines the resolution of texture files. The texture quality should be reduced if the video card has a small amount of video memory (less than 4 GB) or if you are using a very old hard drive with a spindle speed of less than 7200.
Model quality(sometimes just detailing). This setting determines which set of 3D models will be used in the game. The higher the quality, the more polygons. Accordingly, high-poly models require more processing power from the video card (not to be confused with the amount of video memory!), which means this parameter should be reduced on video cards with low core or memory frequencies.
Shadows. They are implemented in different ways. In some games, shadows are created dynamically, that is, they are calculated in real time at every second of the game. Such dynamic shadows load both the processor and the video card. For optimization purposes, developers often abandon full rendering and add pre-rendered shadows to the game. They are static, because essentially they are just textures overlaid on top of the main textures, which means they load memory, and not the video card core.
Often developers add additional settings related to shadows:
- Shadow Resolution - Determines how detailed the shadow cast by an object will be. If the game has dynamic shadows, it loads the video card core, and if a pre-created render is used, then it “eats” the video memory.
- Soft shadows - smoothing out unevenness in the shadows themselves, usually this option is given along with dynamic shadows. Regardless of the type of shadows, it loads the video card in real time.
Smoothing. Allows you to get rid of ugly corners on the edges of objects through the use of a special algorithm, the essence of which usually comes down to generating several images at once and comparing them, calculating the most “smooth” picture. There are many different anti-aliasing algorithms, which differ in the level of impact on the performance of Portal 2.
For example, MSAA works head-on, creating 2, 4 or 8 renders at once, so the frame rate is reduced by 2, 4 or 8 times, respectively. Algorithms like FXAA and TAA work a little differently, achieving a smooth image by calculating only the edges and using some other tricks. Thanks to this, they do not reduce performance as much.
Lighting. As with anti-aliasing, there are different algorithms for lighting effects: SSAO, HBAO, HDAO. They all use video card resources, but they do it differently depending on the video card itself. The fact is that the HBAO algorithm was promoted mainly on video cards from Nvidia (GeForce line), so it works best on “green” ones. HDAO, on the contrary, is optimized for video cards from AMD. SSAO is the simplest type of lighting; it consumes the least resources, so if Portal 2 is slow, it's worth switching to it.
What to reduce first? Shadows, anti-aliasing and lighting effects tend to take the most work, so these are the best places to start.
Gamers often have to do the optimization of Portal 2 themselves. For almost all major releases, there are various relevant forums where users share their ways to improve performance.
One of them - a special program called WinOptimizer. It is made specifically for those who do not want to manually clean their computer of various temporary files, delete unnecessary registry entries and edit the startup list. WinOptimizer will do this itself and also analyze your computer to identify ways to improve performance in applications and games.
Portal 2 lags. Large delay when playing. Solution
Many people confuse “brakes” with “lags,” but these problems have completely different causes. Portal 2 slows down when the frame rate at which the image is displayed on the monitor decreases, and lags when the delay in accessing the server or any other host is too high.
That is why “lags” can only occur in online games. The reasons are different: bad network code, physical distance from servers, network congestion, incorrectly configured router, low Internet connection speed.
However, the latter happens least often. In online games, communication between client and server occurs through the exchange of relatively short messages, so even 10 MB per second should be enough.
Portal 2 has no sound. Can not hear anything. Solution
Portal 2 works, but for some reason does not sound - this is another problem that gamers face. Of course, you can play like this, but it’s still better to figure out what’s going on.
First you need to determine the scale of the problem. Where exactly is there no sound - only in the game or even on the computer? If only in a game, then perhaps this is due to the fact that the sound card is very old and does not support DirectX.
If there is no sound at all, then the problem is definitely in the computer settings. Perhaps the sound card drivers are installed incorrectly, or maybe there is no sound due to some specific error in our beloved Windows OS.
Controls don't work in Portal 2. Portal 2 does not recognize the mouse, keyboard or gamepad. Solution
How to play if it is impossible to control the process? Problems with supporting specific devices are inappropriate here, because we're talking about about familiar devices - keyboard, mouse and controller.
Thus, errors in the game itself are practically excluded; the problem is almost always on the user's side. You can solve it in different ways, but, one way or another, you will have to contact the driver. Usually, when you connect a new device, the operating system immediately tries to use one of the standard drivers, but some models of keyboards, mice and gamepads are incompatible with them.
Thus, you need to find out the exact model of the device and try to find its driver. Devices from well-known gaming brands often come with their own software packages, since the standard Windows driver simply cannot ensure the correct operation of all functions of a particular device.
If you don’t want to search for drivers for all devices separately, you can use the program Driver Updater. It is designed to automatically search for drivers, so you only need to wait for the scan results and download the necessary drivers in the program interface.
Often Portal 2 brakes can be caused by viruses. In this case, it makes no difference how powerful the video card is in the system unit. You can scan your computer and clean it of viruses and other unwanted software using special programs. For example NOD32. The antivirus has proven itself to be the best and has been approved by millions of users around the world.
ZoneAlarm is suitable for both personal use and small businesses, capable of protecting a computer running Windows 10, Windows 8, Windows 7, Windows Vista and Windows XP from any attacks: phishing, viruses, malware, spyware and other cyber threats . New users are given a 30-day free trial.
Nod32 is an antivirus from ESET, which has received many awards for its contribution to security development. Versions of antivirus programs are available on the developer’s website for both PCs and mobile devices, a 30-day trial is provided. There are special conditions for business.
Portal 2 downloaded from a torrent does not work. Solution
If the game distribution was downloaded via torrent, then in principle there can be no guarantees of operation. Torrents and repacks are almost never updated via official applications and do not work over the network, because in the process of hacking, hackers cut out all the network functions from the games, which are often used to verify the license.Using such versions of games is not only inconvenient, but even dangerous, because very often many files in them have been changed. For example, to bypass protection, pirates modify the EXE file. At the same time, no one knows what else they do with it. Perhaps they embed self-executing software. For example, when the game is first launched, it will integrate into the system and use its resources to ensure the well-being of hackers. Or, giving access to the computer to third parties. There are no guarantees here and cannot be.
In addition, the use pirated versions- this, according to our publication, is theft. The developers spent a lot of time creating the game, investing their own money in the hope that their brainchild would pay off. And every work must be paid.
Therefore, if any problems arise with games downloaded from torrents or hacked using one or another means, you should immediately remove the pirated version, clean your computer using an antivirus and licensed copy games. This will not only protect you from dubious software, but will also allow you to download updates for the game and receive official support from its creators.
Portal 2 gives an error about a missing DLL file. Solution
As a rule, problems associated with missing DLLs arise when launching Portal 2, but sometimes the game can access certain DLLs during the process and, not finding them, crash in the most blatant manner.
To fix this error, you need to find the required DLL and install it on the system. The easiest way to do this is using the program DLL-fixer, which scans the system and helps quickly find missing libraries.
