OBS 28 acting strange with Mount & Blade II and I have tried 1 and two video cards installed.

Most of my other games, I can stream really well, with this one, something is going on really bad.

First OBS uses 25% GPU just launching. This is whatever game I am streaming, doesn't matter. How do I lower the GPU usage of OBS just sitting there idle?

I have tried launching it as Admin and a bunch of other things I have read / watched on the internet, and it always is using 25%. Also there was a video to set some Nvidia settings, tried that also. No dice to get it to stop using 25% GPU just sitting there.

Then when I launch Mount and Blade II Bannerlord, and I am not streaming yet OBS GPU Usage goes up to 95%. Note I am not streaming yet, and you can see that bannerlord is not using much CPU at all, in fact just sitting in the menus:

If I start streaming, my second video card (I have OBS set to use that video card to stream) I use 10% of that GPU as it's streaming, but because the main OBS process is eating up 95% of my GPU I simply can't stream using this method (audio gets choppy, graphics are lagged, etc.). My CPU is usually around 57% at this point. (I have an AMD Ryzen 9 3900x)

Anyone have some suggestions I could use to stop OBS using up so much CPU just sitting there or when the game is launched and I am not even streaming yet?

I found the problem with this, I was using the Nvidia plugin inside OBS to do noise supression. This caused the horrible spike in GPU usage in OBS.

I now have Nvidia Broadcast running outside OBS and it works fine.

You can see here with the game running, significantly less GPU usage:

Hopefully this will help someone else. :-)
