Modern computer games look much more impressive than a few years ago. Technologies have stepped far forward, now developers have much more opportunities to implement their ideas in this area. However, this does not mean that those projects that came out earlier lose their relevance. If the game is good, then it will be good at any time, even when its graphics are completely out of date.
For example, you can apply this to GTA 4 - one of the best computer games that humanity has seen. And if modern projects require incredible resources from your computer, then games that came out just a few years ago have much lower demands. In the case of GTA 4, the system requirements for Windows 7 and other systems were quite high by the time the project was released, but today almost every computer can give you the pleasure of launching this game.
operating system
If we consider the game GTA 4, the system requirements for Windows 7 will correspond to the requirements for other systems, but at the same time you need to pay attention to the fact that there is a chance that you will have to sweat a bit to launch the game. In fact, there is nothing complicated. You just need to run the game in compatibility mode, preferably with Windows Vista. Why exactly this version of the operating system?
The fact is that this project was developed just for this OS, and the "seven" at that time did not exist at all. Accordingly, in some cases, certain compatibility issues may occur. So if you have installed the seventh or eighth version of Windows, then there is a possibility that you will have to dig into the settings a little in order to start GTA 4. System requirements for Windows 7 are not different from other OSs - that's about them now and speech will go.
CPU
As mentioned earlier, in GTA 4 the system requirements for Windows 7 are no different from those that are prescribed for other systems. In addition to a small compatibility problem, nothing special is observed, so the most reasonable solution would be to describe the requirements in general, and not in particular.
So, if we are talking about the processor, then here you will need a dual-core version with a frequency of 1.8 gigahertz - these are just the minimum requirements, so you can start the game at the lowest settings. If you are aiming for something more, then you will need to increase the core frequency to 2.4 gigahertz - only in this case you will not experience any problems with the game.
As you already understood, for GTA 4 the system requirements for Windows 7 x32 and other versions now do not look very impressive, but at the time such computers were considered quite powerful.
RAM
As with other computer games, RAM is the most important indicator when considering which system requirements are presented for GTA 4. For "Windows 7: Maximum Version" you will need to make sure that the paging file is configured very competently - otherwise you will need one and a half gigabytes of RAM to run the game at the minimum settings. If you want to play without glitches and with maximum settings, then you will need to increase the RAM to two gigabytes.
Video card
Please note that the appearance of this game is impressive even today. Naturally, he does not stand close to modern projects in which the schedule is as close to realism as possible. But compared to other projects of its time, GTA 4 now looks very decent. But at the same time, if you look at the requirements for a video card, you may be surprised. The fact is that to get the perfect picture you need only 512 megabytes of video memory. If you do not strive for ideal, then 256 megabytes may well be enough for you.
