Question / Help high cpu utilization on streamlabs obs with an i9 9900k

[TheTrollingTrooper]

I am troubled as my processor performance while streaming games like the wicther 3 or fortnite, even lowering the resolution and the birate seems to me to be some problem with the performance of mine cpu.
I use SLOBS and the program even uses 40 percent of my cpu during streaming.
Thanks to those who help.

Ask streamlabs then. We didn't make slobs, we don't provide support for it.

Sorry for that, but this inssue happens with normal OBS too, can you help ?

if you have the same issue in obs then upload the obs log

if you have the same issue in obs then upload the obs log

Hello, thank you for your reply, thats is my log form my last stream : https://obsproject.com/logs/0z2xc7jyXsI3m2HM

No output session in log. Open OBS, begin an output session, observe your issue, stop the output session, upload the Current log without quitting OBS.

The only stream attempt here ends in a connection error:

I believe that is correct, I am streaming LOL in this test

You're using x264 encoding for 1080p60. x264 uses the CPU to encode, and 40% CPU usage is absolutely the expected usage for your CPU. You do not have a single frame lost to either rendering lag or encoding lag, which means OBS has all of the processing power it needs to perform its function.

If the CPU usage is interfering with other programs, you can try lowering the priority of OBS in the advanced settings, or you could try using the NVenc encoder, as that will use your GPU for encoding instead of your CPU.

Thank you for your reply, one more thing, you belive that playing while streaming the wicther 3, the cpu use will be highter?

Yes. Witcher 3 is a much more demanding game. Just have your task manager up (ctrl-shift-esc) on the side while you play and you can see the realtime CPU usage under the Performance tab.
