What causes Valorant’s high CPU usage?

Numerous factors can cause the high CPU usage in Valorant, and some are:

  • Outdated graphics drivers – Running an outdated graphics driver on your PC can cause problems with how much system resources gaming activities will consume. It is because the graphics cards can fix bugs affecting the current version, resulting in high CPU usage in high-end games like Valorant,
  • Interference from third-party apps – The activities of other apps running on your computer can affect your game. They can take up excessive bandwidth and system resources, leaving Valorant to overwork and not give enough system resources for the game.
  • Issues with Windows Defender Real-time Protection – When you have the Windows Defender scheduled scan running on your computer, it can cause problems with the Valorant game and result in high CPU usage. The scan delays the game activities, causing it to take longer to load.

You can fix the problem by troubleshooting the game and your PC.
