Question / Help OBS software only is lagging on high-end pc, not the game

[Wtftaxi]

Hello,

I have SLI 2080ti, 9900k processor and all that good stuff. Now, my games (WoW, Overwatch, CS:GO etc) never lags, but when I open OBS its lagging in the software but not in my actual game. I tried to limit my fps in-game in CSGO, but no luck. I've tried to google (Its very hard when you have OBS and LAG in the same search) a few things and tried that, but that doesnt help either. Why is every game I try lag inside of OBS, but not on my PC? I tried to reinstall and right now I'm even trying out Streamlabs-OBS, but that doesnt help either.

Ofcourse it lags over to my twitch when I press "Start streaming". Any solutions to this?

PS; on my old pc that had SLI 980ti cards had no problems streaming with OBS. All my drivers are updated. Even flashed bios to newest in hopes of having it work.

Thanks for all the help.

Here is my speedtest result 74/23. Should not be bandwith limited.

18:10:51.356: Output 'simple_stream': Number of lagged frames due to rendering lag/stalls: 284 (17.0%)

Rendering lag is caused by GPU overload.

18:10:51.356: Video stopped, number of skipped frames due to encoding lag: 417/1559 (26.7%)

Encoding lag indicates that the hardware encoder you've chosen (NVENC) cannot render frames in time with the settings you have chosen.

Neither of the above problems are related to network, but to measure your connection's performance use TwitchTest. Generic speedtest results are not relevant in this case.

Great answer, thank you very much for the help! I'll test it out when I get home from work. Hopefully it will help. Thanks!
