Obs constantly eating my cpu

[Fiolettovy]

So for some reasons since a while ago my obs is just eating my computer.
Here me out. Even if not in stream capturing or basically not doing any single thing at all, if obs is open my cpu cap to 100% and my computer is basically glitching out, sound is getting crunched and I cant do anything but alt-f4 obs.
I don't know what to do, I've tried any single thing internet could provide but still nothing.
There is nothing I can say than that so if anyone can help it would be a pleasure.
Thanks in advance

1. do you use 3rd-party plugins?
2. do you auto-enable virtual-cam after obs starts?
3. any wrong sources?
4. any driver issues for videohardware (cams, streaming cards etc)
last resort: uninstall obs - delete obs folders and settings - re-install obs = fixed?

No plugins (basically because Idk how to have plugins) I do not use any camera or anything, I removed all my sources but still laggy, my driver are up to date (all of them, I triple checked)

even without ANY source your OBS takes 100% cpu?

mh, maybe you should also consider doing a clean windows install - because this is not normal

I noticed this too from my recent build of OBS 31.0.0-beta1 inbuilt with cef_binary_5060_linux_x86_64 for obs-browser. By "idle" I mean no sources active in a very rough sense. Normally, idle OBS uses about 3% cpu in my laptop with linux. But for this build it was using about 27% while idle. I tried locating the cause of this issue through very many means and eventually discovered it could possibly be caused by CEF (obs-browser). I deleted all browser sources and then restart OBS. You must restart for changes to happen. Then idle CPU usage dropped to the normal one about 3%. I noticed that creating a new browser source (even one with the default url), idle CPU usage spikes to about 27%. Deleting the dummy browser source and transitioning does nothing to lower CPU usage. Change only comes upon restarting OBS. I'll try building OBS 31.0.0-beta1 using a different CEF binary and see if there's any difference. Time to make use of DuckDuckGo for stuff I don't quite understand atm .

So Fiolettovy, my advice is you delete all browser sources and restart OBS, then see if there's a difference. Backup the scenes before deleting incase you don't wanna go through reconstructing your browser sources again.

I've rebuilt OBS with several different CEF binaries from https://cef-builds.spotifycdn.com/index.html and https://adamcake.com/cef but the OBS CPU usage spikes immediately I create a browser source for each build. So I'm starting to think that this CPU spike bug is from OBS 31.0.0-beta1 itself (also the current master branch) rather than CEF. I don't know what else to do other than file a bug report. I haven't been able to rebuild lower versions of OBS because I keep getting Unknown CMake command "set_target_properties_obs" error during build configuration stage. Now I need to test different OBS versions to see if it's an OBS regression or something else. Anyone care to help me solve this build configuration error?
