How can I fix OBS if it’s registering high CPU usage?

1. Update GPU driver

The OBS’s high CPU usage can be due to outdated or faulty drivers. This is because the app requires proper drivers to function well. So, if your GPU card driver is outdated, it might cause it to use too much CPU. If the Windows driver updater cannot find the needed drivers, you can go to the manufacturer’s website to download the latest version. Alternatively, you can use a dedicated driver updater in DriverFix to update your drivers. This tool automatically scans for outdated drivers and updates them before they can cause problems.

2. Reduce output resolution

Your stream screen resolution determines the quality of the output. However, if it is too high, it can cause OBS to register high CPU usage. Hence, you might need to lower it to fix this issue.

3. Reduce the frame rate

The frame rate determines the number of frames captured while recording. Unfortunately, this can also lead to the OBS high CPU usage issue if it is too high, as it strains your resources. Thus, it would be best if you reduced it to balance resource usage.

4. Change the X264 preset

The X264 is the video source library used by OBS for video encoding. It gives you options to balance your CPU usage and video quality. Hence, you can determine how much of your CPU OBS uses during the encoding process. However, it is essential to note that the high the preset value, the lesser the CPU usage. The only downside is that choosing a high value like ultrafast will affect your video quality.

5. Update your PC

OBS is a resource-intensive software and needs your PC to be firing on cylinders to function well. Hence, if your PC is outdated, it might cause OBS to register high CPU usage. There you have it: everything you need to fix the OBS high CPU usage issue. We believe you should be able to fix this issue for good and use the excellent stream software without worrying if you follow this guide’s steps carefully.
