NVENC Error: Too many concurrent sessions

I've been trying to fix this all day and I have found no solution, OBS seems to tell me the issue of NVENC using too many sessions but I have no idea what else is using NVENC. I've tried to record not using NVENC but the output ends up being really blurry. If anyone knows how to fix this or find what else is using NVENC please do let me know!

Depending on the driver you have installed, there could be 2 or 3 concurrent sessions running. If you want to see how many are running, Open a command prompt and type: nvidia-smi.exe encodersessions

To clear them, just re-start your PC.

I'll try that, using the command prompt I get an issue saying the exe isn't recognized, gonna try restarting my computer now

Some VR headsets use up 1 nvenc session, even if not in use. The windows internal recording (accessible from the Windows Game Bar or from Windows settings->Game->Recording) as well, but only if you activated background recording.

I used to have a PSVR connected to my PC but got uninstalled everything for it since i never used it, restarted my pc and still no luck. Does command prompt need to be open in a specific filepath to test the exe thing?

I'm gonna be honest I'm not entirely sure, I have the GeForce experience and usually that handles driver updates. how would I check?

Good, at least it's working now. Post the log from the recording session you just did, there may be some adjustments needed.

Please post a log with your issue! Here's how...

OBS Studio creates a log file each time you run it which contains very useful diagnostic information. Without a log file, it's much harder for any support volunteers to figure out problems and your post may be ignored. To upload a log file, go to the Help menu > Log Files > Upload Last Log...

Do you have SLI enabled? Your log shows OBS loading up on the 1060 & it also shows these errors.
