Question / Help High CPU usage whilist using nVenc

[blocikinio]

Hi,
something is probably wrong with my obs studio.
When I set up everything to use nVenc my obs starts using 3-4% cpu, but after few minutes it raises to 20-25% and it should not. I've checked even the previous version i mean the normal obs and there is no bug like this.
Wanted to add that disabling preview window lower the cpu usage to about 9-10% so I do not know where the problem is.
Sorry for my bad english :)

Hi,

We need to obs log after you have experienced this issue, how to provide this can be found here https://obsproject.com/forum/threads/please-post-a-log-with-your-issue-heres-how.23074/

Ok, here it is

Thanks for any help.
Obs classic > obs studio.

I even fully reinstaled obs studio but it happens over and over. Another log.

Hi,

I see you are streaming you should use x264 software as the encoder for this over Nvenc which is best used for recording. Try changing this as you will get a better quality stream given the low bitrate.

The log is showing "Number of memory leaks:19" though I can't see whats causing it maybe someone else help.

Yeah, but the not optimised games like Path of Exile/H1Z1/ and newest games took almost 70% of CPU usage outta nowhere so it's safer to stream using nVenc. Youtube provides even 8k bitrate so there is no problem to use this encoder.

EDIT: it doens't take place on OBS classic.

I used x264 for 30 minutes just to test. Same problem. Memory leaks.

No one could find solution so I found it by my own. Memory leaks was caused by nVidia shadowplay option on.
