Computer games, unfortunately, are not ideal - they remain programs that are created by man. Moreover, the program is incredibly complex, multi-level, so that absolutely every gamer can have an error, regardless of the configuration of the computer or installed software. Accordingly, you need to be able to solve such situations, and not to panic or complain about developers who have not eliminated all the errors. The fact is that in most cases the cause of the error lies precisely in your computer, so it makes no sense to blame anyone - it is better to understand everything in detail. In GTA 4, a critical error, for example, appears very often among many gamers. It may contain different text, depending on which you will need different actions. It is immediately worth noting that most of these problems are solved by restarting the game, restarting the computer, or reinstalling the game. Such cases will not be affected in the article - here you can only read about those errors that are solved in other ways.
RMN error
If your critical error in GTA 4 contains the text RMN, followed by the value 20, 30 or 40, then you will have to reinstall the system. The fact is that these errors mean that the wrong OS is installed for your version of the game. In case of an error with a value of 20, you need to install the first service pack - this error occurs on Windows Vista. The other two options appear on XP - the first means that you need the second service pack, and the second, respectively, means that you need to update the OS to the third service pack. If you have a later version of the operating system installed and a similar error occurs, then you can solve it very simply - using the compatibility mode. But, as mentioned earlier, in GTA 4 a critical error of this kind arises mainly only on Vista and XP systems.
Graphics card issues
The most famous and common critical error in GTA 4 contains the following text - DD3D50 D3D. It is it that arises among many gamers, and they can not cope with it in any way, no matter how much they reinstall the game. In fact, reinstalling here will not help, since the essence of the problem lies in your video card. This error occurs only on very old computers, because it means that the video card installed on the PC does not support the DirectX 9 distribution. The fact is that today many new projects do not support the ninth version, since the eleventh is the most common. However, note that this problem may occur if you do not have drivers installed on the video card or if an outdated version is installed. You need to update the driver, and then the error may disappear. Many believe that in GTA 4, the WS10 critical error is related to the video card, but in fact it is not - this problem is solved by simply restarting the computer.
Shaders
It is also worth paying attention to the fact that a similar error - DD3D60 D3D - occurs if your video card does not support shader version 3.0, so you have to change the video card. Naturally, this is not very good news, but it is unlikely that it will catch anyone by surprise, because most modern video cards already support version shaders 5.0. Thus, if you have this error, then your video card is seriously outdated, and you need to change it anyway. However, before doing this, check the same drivers for the video card, because their absence can also cause a similar reaction of the game.
Error AE10
As you already understood, most of the errors that cannot be resolved by restarting or rebooting relate to the video card. In GTA 4, a critical error RMN60 is one of the most common, not related to the video card. Also, such errors include the AE10, which informs you that your computer does not have enough memory to start. To solve this problem, you just need to close the extra applications.
