Question / Help OBS lags but my game doesn't

[manlystantler]

I recently got a new setup so put all my games on max settings and I tried to record rainbow six using OBS but right after I choose my character my recorder suddenly drops to 0.5 to 15 fps while my actual game tab is getting a solid 160+ constantly. I lowered my game to minimum settings and OBS still sits between 10 to 25 fps and has close to no affect on my game. I tried using the Geforce built in recorder and it was recording flawlessly with above 100 fps on max settings. I've spent hours fiddling with these settings trying to get OBS to even hit a solid 30.

Check that Game Mode is not on in PC Settings.

21:45:41.374: Windows 10 Gaming Features:
21:45:41.374: Game DVR: On

Turn that off as well. There are instructions in the link at the bottom of this post.

21:49:25.398: [NVENC encoder: 'recording_h264'] settings:
21:49:25.398: rate_control: CBR
21:49:25.398: bitrate: 20000
21:49:25.398: cqp: 0

Don't use CBR rate control with NVENC for recording. You should use CQP with a value roughly between 15 (high quality) and 23 (good quality). CBR is primarily for streaming on platforms that require it. Using CBR with NVENC will result in larger files without additional quality.

Your GPU is overloaded.

If either Game Mode is not on, or turning it off does not resolve the issue, check here for other things to try:
