OBS using too much CPU: How to fix it

Instead of waiting and only thinking of these tips as solutions to problems when they occur, it's good to think of these as optimization procedures to employ routinely, except applying for them more stringently if there does occur a high CPU usage problem.

1. Scale down your resolution output

2. Reduce your frame rate

3. Close excess programs and lower OBS processing priority

4. Run your audio sources at the same frequency

When you run different audio frequencies for screen capturing, it will load more processes onto your CPU – it has to load at each frequency. In order to minimize the amount of work your CPU has to do, it’s best to run each audio device at the same frequency. You don’t want your desktop audio to run at 44.1 kHz and OBS to run at 48 kHz as it will affect the performance of your system. 

5. Change the x264 preset

6. Double check all sources

7. Time to upgrade your hardware

8. Encode with your graphics card

9. Perform a disk cleanup and clear space

10. Disable Game Mode

11. Update or downgrade your version of OBS

12. Use an alternative screen recorder
