Hey,
i have a very big problem.
As soon as i open OBS Studio, the Desktop is lagging and also Games that are running in Fullscreenwindow.
Also sometimes the whole Mouse Pointer is hanging for 2-4 Sec. As soon as i run a game in fullscreen, everything is just fine.

What could be the Problem?

My Rig:
Windows 10 64 Bit
i7 4790k
GTX 980ti
SSD Main Drive

I think my Rig is good enough to stream. Also the problem doesnt change if i downscale the Picture.

Hopefully someone can help me?

What is your cpu usage when your in windows desktop (when it laggs)?

Did you untick "Multple Adapter Compatibility"?

Also i dont find the Option Multple Adapter Compatibility. Where is it exactly?
The Problem isn´t only when i stream. Also when i just startup the programm. When i delete the Desktop Source the lags are gone

I am having the exact same problem. I too cannot find the Option Multiple Adapter Compatibility. Also my mouse is a few seconds behind then it crashes on me. I have uninstalled and reinstalled. I have a pretty dang powerful computer set up and I'm hardwired directly from my internet source to my computer (no wifi usage). I'm guess there is some computer setting I'm missing because there is no reason it shouldn't be working. I have more than enough memory, ram and only run around 8 or 9 CPU until I open OBS. The minute I open it I'm up to 65 on my CPU usage and nothing will work.

Only thing when i saw something like that, was when my gpu didnt throttle to an higher performance level.

OBS Studio uses more advanced DirectX stuff. When enabled it should ask an higher gpu clock for it. When it doesnt throttle it stays at low clock, but the graphics performance is to high for the low gpu clock. Thats maybe why also when you go fullscreen in a game, that it throttles again.

You can check this with nvidia inspector or some GPU monitor. Most custom cards have their own gpu monitors. Look what your gpu does when you enable OBS.

Can you include the Crash.log (if there is any) and the current log. See help tab.

i fixed my problem by going to my drivers and updating my graphics card driver. It was as simple as a driveer error.
