You can use the Windows 11/10 Optional Updates feature to update your graphics card driver.
You can download the installer file from the official website of your graphics card manufacturer and install it manually.
You can update your graphics card driver from the Device Manager by following the steps below:
- Launch the Device Manager by right-clicking on the Start menu.
- Expand the Display adapters node.
- Right-click on your Graphics Card driver and select the Update driver option.
- Now, click Search automatically for drivers. After this, Windows will uninstall the latest version of your graphics card driver automatically.

3] Change Windows Defender Real-time Protection feature settings in Task Scheduler

The problem might be occurring due to the scheduled scan of the Windows Defender Real-time Protection feature. You can check this in the Task Scheduler. If you find Windows Defender scheduled scan there, change its settings and see if it fixes the problem.

The following instructions will guide you on this:

Launch the Run command box and type taskschd.msc. Click OK. This will open the Task Scheduler.
In the Task Scheduler, expand the Task Scheduler Library from the left side and go to Microsoft > Windows > Windows Defender.
Check whether there is Windows Defender Scheduled Scan on the right pane. If yes, double-click on it. A new window will appear.
Under the General tab, uncheck the Run with highest privileges checkbox.
Now, select the Conditions tab and deselect all the options there.
Click OK to save the changes.

4] Disable HPET (High Precision Event Timer)

The HPET (High Precision Event Timer) produces periodic interrupts at a higher resolution. It is used to synchronize multimedia streams. In some cases, HPET affects the gameplay and causes micro stuttering, and also decreases the FPS in games. In your case, HPET might be the cause of high CPU usage by Valorant.

Some users have said that disabling the HPET in Windows OS has fixed the Valorant high CPU usage problem. You can also try this. Disable the HPET and check if it fixes the issue. To do so, go through the following instructions:

Right-click on Start and select Device Manager.
Expand the System Devices node.
Right-click on the High precision event timer and select Disable device.
Restart your computer.

After restarting your device, check if the issue persists.

5] Exclude Valorant game and anti-cheat folder from Windows Security or your antivirus

Windows Security protects your computer from potential threats. When Windows Security runs a scan on your system, it usually consumes more CPU. If you are experiencing a high CPU usage issue with Valant, it might be possible that Windows Defender or your antivirus software is running a scan for Valorant. To solve this issue, you can add the Valorant game and anti-cheat folder as an exclusion to Windows Security and to your third-party antivirus.

6] Troubleshoot in a Clean Boot state

The issue might be occurring due to conflicting third-party software. Troubleshoot your computer in a Clean Boot state to identify that software. Once you find the culprit software, consider uninstalling it.

How do I fix high CPU usage?

There are several causes of high CPU usage on a Windows OS, like corrupted system files, conflicting software, etc. To fix this problem, you can run an SFC scan, DISM scan, chkdsk scan, update your device drivers, etc. Running the Performance Troubleshooter can also help fix the problem.

Hope this helps.
