Performance issues with 2080Ti

So I've been having issues with getting the card to stream. I can run games at 4k ultra easily with no issue, but the second I go to stream the stream output ends up choppy as hell. I've already tried changing various settings in OBS including switching from NVENC to x264 (made it worse somehow?), adjusting down to 720p 30fps, adjusting the bitrate to various recommended amounts, etc. I have managed to get a fairly smooth stream at 1080p 30fps if I set the graphics all the way down to Medium on Assassin's Creed: Odyssey. 

If downgrading graphics in order to stream is the way I have to go I'll accept it, but I can't help but feel that's pretty underwhelming for a $1400 card? I have checked my upload speeds and they are reasonably fine (25-30mbps). I'm fairly sure the choppiness is coming from my system because I can see it in the OBS preview without even having to watch the recording on Twitch afterwards. I have noticed in monitoring thru task manager that when streaming the GPU usage frequently spikes to 100% when running anything higher than medium while streaming. Is this normal? 

I tried benchmarking with 3dMark Timespy and got a score of 9588.

What if you used CPU encoding vs GPU encoding?

Not sure if it will help or fix the issue, but it seems like you have yet to try this.

GPUs typically have a separate thing for encoding/decoding video, so it shouldn't be affecting the GPU's performance in games.

 

But it wouldn't hurt to try anyway.

Task Manager will show the highest "engine" being used in the left summary panel.

The defining theory of troubleshooting, lol.

Alright so! In the task manager where it breaks up GPU usage I watched that while attempting to stream at Very High. Video Encode was only at around 8% the entire time, Copy was 2%, and 3D was at 98-99% the entire time. Frame rate kept dropping from 30FPS to 6-8 FPS on the stream, but not in my game. 

Tried again this time using x264 instead of NVENC so the CPU would handle the encoding. CPU handled it fine, highest was around 62%, but the 3D part of the GPU was still 98-99% the entire time, same low frame rates. 

I don't really understand what could be the issue with it. When I run the in-game benchmark at Ultra I easily get 50-60 FPS on 4k. I get the same while playing. It's only in the stream that it seems to have an issue. 

Tried Task Manager again just playing the game without streaming. Utilization of the GPU/3D was 99% the entire time, but it easily stayed within 50-60FPS on very high.

Try to DDU your drivers and see if there's any improvement.

Used DDU to uninstall drivers and then did a clean install from the Nvidia website of the most recent 419.67 driver. Restarted after it was loaded and tried again. Still getting 99% utilization of GPU and frame rate dips in OBS to 14-25FPS instead of the target 30FPS.

For the record I've fixed the problem. Had to turn off Game DVR in Windows settings, Shadowplay in GeForce Experience, and disabled hardware acceleration in Google Chrome and I'm now able to get 1080p 60fps with no stutters at high settings on AC: Odyssey!
