Not sure why this is happening, or what caused it to happen.
When I have OBS open (not streaming or recording), and I go into a game such as CS:GO I get severe frame drop/stutter. It seems to somehow be linked to Game Capture source. When I disable game capture and go off of Display Capture source things look/feel better, and I can see the improvement when watching in game fps. I'm looking for any help in solving this issue, and putting this out here to hopefully help some people that had the same issue as me because it literally made the game unenjoyable to play. All of my drivers/bios/obs are up to date. I have tried everything to the best of my knowledge with adding, and removing programs that were running, and diagnosed the issue by adding and removing sources in OBS after finding the issue to be linked to OBS running. Thanks in advance to anyone that helps! Also I've tried adjusting every setting in my output settings/video settings and there was not change.

So to clarify b/c I know I'm a bit scatter brained when on forums my fix was the delete the game capture and just use display capture.

****EDIT**** Also I've concluded it has something to do with dual monitor setup. If i disable dual monitor and just use my primary monitor things seem to work better.

https://gist.github.com/ecdb09d694bb12954bb3b0ede08a3627 I think this is a log file where I enabled the game capture just to have a log file to upload with this issue happening. I saw it happen 3 or 4 times within this short maybe 1 min log. If this isn't the right one ill try to make another one.

Also I forgot to add. I could open csgo and everything be fine then open OBS not streaming or recording and I would get my FPS cut in half and it would stay there. Also I was getting low CPU usage from the game. Then I would close OBS and restart the game and my frames/cpu usage would be normal.

This was fixed when installing-- Windows 2018-02 Cumulative Update For Windows 10 Version 1709 for x64-based Systems (KB4074588)

I found the fix for me, and it also worked for a few of my friends.
Click GAME CAPTURE on your source list
Check the box "Limit Capture Framerate"

Now I can finally play any game dual monitor with anything I want on either monitor, and I get ZERO fps drop or Stutter!!! Its so nice. When the box wasn't checked and I had OBS open(not recording or streaming/just open it could even be minimized) with game capture on I would get like 30 fps in CS:GO and barely any of my CPU was getting used.

Hello, I made this account to help some people that's still looking in 2022.

So if your pc in-game drops frames when OBS is open and when it's closed it's fine.
If you go into task manager and OBS is using way to much memory.

If you got a mic installed on OBS, as the on that you set up to talk, if you put a filter on it called ''Noise Suppression'' inside you have 3 options.

Spexx.
RNNoise.
Nvidia Noise removal.

MAKE SURE ''Nvidia Noise removal'' IS NOT SELECTED.

Its Resource hungry.

My Specs.

3070 TI Founders, X570s arous, 1TB m.2 arous, 16GB 3600Mhz Ram.

So pc is perfect to run any AAA game and high and stream in 1080p.

Hope this helps, Happy 420
