Highly random CPU usage (online&offline)


New Member
Hi all !

I recently restored a clean version of my streaming PC.
Since then I'm getting high CPU usage on a random basis.

Let me explain :
  • Sometimes I spend hours livestreaming (NVENC) + recording (x264) without a hitch.
  • Sometimes I just boot up OBS, not even going live, to find my usual 10% CPU consuming main scene suddenly using 40 to 50 percents.
  • Sometimes, as shown in attached log file, livestream+rec is going well, until OBS inexplicably start ramping up CPU usage. When this happens, the only way to go back to normal isn't just to go offline, but to close and relaunch OBS.
I really could use your help on this one :)
