Question / Help Ingame fps problem

[Mir0]

I have a problem with my fps Ingame.

I found similar threads from years ago but with no fix for the problem.


Normally my PC manages to run R6 ( i mainly play Rainbow6) on stable 144fps on ultra high with a running 720p Stream on Twitch but since 2 Weeks or so i get only an average of 60-70fps (i set all settings in R6 to medium and get 80fps on some maps) , sometimes it even drops to 46fps.
Without OBS everything is fine but with it, it cuts my fps in half.
OBS runs in stable 60fps without any problems.

PC Specs: i7 8700K, RTX 2080, 16GB RAM
3 Monitors, 2 with 144Hz and 1 with 60Hz (it can only run 60fps)
I tried x264 and nvenc and nothing changes.
With Stream my CPU is at 55% and Ram at 51%.

I also have that problem with Mordhau. On Stream it is almost unplayable.

I have the newest GPU driver, updated Win10 and the newest OBS.

I'm new to PC, i switched from console but i understand most of it so please help. :D

Thanks in advance.

Have you tried disabling the OBS preview? Windows 10 has issues dealing with multiple monitors having hardware accelerated window displays across different refresh rates.

So it could be the problem that one Monitor is only at 60hz?

No i haven't tried it. I will give it a try.
