High GPU usage on OBS and Desktop Windows Manager while OBS is opened

[Porkys]

Hello I have one problem with Desktop Window Manager and OBS. When I am going to start stream (obs) my Desktop Window Manager jumps to 80-90% usage and OBS is taking like 12-20% or more while i am IDLE . And when i am trying to play, it is imposibble. I would appreciate any answer. I watched every video on YouTube and none of them helped me. I was thinking about windows reinstall. But I will try this first.
PS: Desktop WIndow Manager is runninig at 15-20% without obs which in my opinion is high.

What GPU do you have? Do you have dedicated GPU as well as an active onboard GPU (e.g. Intel HD Graphics)? This has been known to sometimes cause high DWM GPU usage and some changes in NVIDIA Control Panel can sometimes sort it.

I was referring to discussions like these:

For various reasons I did a full DDU removal and reinstallation of DCH drivers late last year and I've not noticed DWM GPU usage go above 10% with Chrome & OBS open while streaming and NVENC encoding.

In System Setitings > Graphics Settings (just type "graphics settings" into the Start menu), I have Hardware-accelerated GPU scheduling enabled, and I have OBS, Chrome and a handful of other apps explicitly included for "High performance" in the Graphics performance preference section.
