CSGO is a first-person shooter game that requires a lot of CPU power to run. It’s not uncommon for the game to use up all of your CPU, which can cause stuttering and other issues. 

So, if your computer is running slowly or you are getting lag and FPS drops, it could be because the game uses too much CPU. 

Why does CSGO take so much CPU? 

There are many reasons why CSGO might be using too much CPU. Some of them are:

  • Virus/malware – If you’re not equipped with a comprehensive antivirus solution, there may be some malware or adware causing this problem.
  • Multiple CSGO processes – If you have multiple instances of the game running at once, they could also be consuming a lot of CPU.
  • Old OS – CSGO undergoes updates from time to time, so if you’re running an older OS with the new version of the game, it is possible that it has not been optimized for your Windows version.
  • Outdated graphics card – If your graphics card is not powerful enough to handle all of the on-screen action at once, you will experience high CPU usage in CSGO. This is common if you have an older card or laptop that doesn’t support newer technologies. Hence, you need to update the driver to get the best performance,

How do I fix high CPU usage in CSGO?

2. Test your hardware for stress

  4. Restart your PC.
  5. Go back to Steam and reinstall the game.

5. Get an SSD for faster load times 

If you’re playing CSGO on a PC with a spinning hard drive, you may notice that the game seems to run slower than it should. This is because your computer spends a lot of time waiting for information to be read from the disk.

To get around this problem and make your games run as smoothly as possible, you need to move your game installation to an SSD. An SSD is much faster than a conventional hard drive and can significantly reduce load times in most games (but not all).

In other instances, you may find that CSGO is not using your CPU. CSGO is a very CPU-intensive game, so if your CPU isn’t powerful enough to handle the game, you will experience freezing and stuttering, ultimately affecting the performance and leading to low FPS.

However, if you have a powerful graphics card, a dedicated GPU might be able to take some of the load off. If this is the case, you’ll notice that CSGO is not using as much CPU or very low CPU usage.

In most cases, CSGO’s high GPU usage is not a problem. It’s simply the game running as it should. However, if your computer has an older graphics card, you may want to ensure that the game isn’t overworking your GPU.
