Question / Help Losing 200FPS but even not streaming / recording

[Stilgarius]

Hello,

I have big problem with CS:GO - I want to stream It but I lose ~150/200FPS just by catching it on my OBS. When I play CS:GO I have ~300fps+ but when I turn on OBS and enable capture game FPS drops to ~90. I dont know what's going on. I even didnt press start recording or start streaming, just by enabling game capture i lost ~200 fps. Anyone know how to fix it?


My PC:
Ryzen 7 1800X @3,9Ghz
GTX1080Ti
Corsair Vengeance RGB 32GB @2666MHz
144hz 1080p monitor

Vsync off, nvidia options turn full on performance.

Post your OBS session log from that session where you have trouble.

Well if this can help - I even didnt start streaming/recording so I dont know if You cant find any information there.

Few things
1> don't have display capture and game capture sources in the same scene
2> don't have multiple game capture sources across your scenes, use the hotkey based window selection
3> turn OFF multi-adapter compatibility hooking in your game capture source.

Holy moly man :D I dont know how but It works :D I finalyl have good FPS even when recording. I just deleted display capture and only game capture remain in this scene, turn off multi adapter compatibility and right now I have a lot better FPS in games.
I have been streaming with wrong options for like year and getting so mad that my CPU cant handle it :D Thanks!

multi-adapter compatibility hooking is "slow ass cpu based capture" rather than the default "buttery smooth gpu based capture"
