HIGH CPU LOAD

[magoygoh]

Hello everyone!


I’m a user of the Zorin OS 17 system (recently migrated) and I stream using OBS Studio. I noticed that, unlike on Windows where I used to get at most 12% CPU usage, on Zorin OS OBS is reaching around 20%. I believe this is not normal.

I'm using ffmpeg's AMD Radeon settings and scaling the stream to 720p to reduce throttling, but the high CPU load persists.

Thank you in advance for your help.

You give almost no info. Attach a log. There can be quite a difference between Windows and Linux. Especially when it comes to browser sources as they are often not hardware accelerated on Linux.

Here's some information:

• The vast majority of the scenes I use are made up of just a 2-second looped webm video.
• The scenes that have some browser sources, like alert boxes, are the ones that use the least amount of CPU processing.
• When idle, even in scenes with only a video loop being displayed, the CPU usage is between 18% and 20%.
• I'm currently using Zorin OS 17.3. With these scenes and the output settings encoded for the GPU (my GPU is an AMD Radeon 550), the CPU usage is around 18-21% while idle.
• With the same settings on Windows, OBS previously had a maximum CPU usage of 13% when idle, and that was on rare occasions.

I believe OBS isn't working correctly on the system for two reasons:

• When I close OBS Studio, even with the "quit obs" button, when I open it again, it shows the message "OBS did not shut down correctly, open in safe mode or normal mode?".

A static OBS operation log is attached.
