Hi! Decided to give OBS a real shot today after I started getting static issues with ShadowPlay and my new microphone setup. I've done a bunch of testing, and if I can get OBS to work perfectly this should fit all my needs perfectly.
When I try to record with NVENC H.264, I get this error:
Having a bit of a tinker, switching to x264 as the recording encoder, recording for a bit, then switching to NVENC again solves the issue for that recording, but as soon as I close out of OBS again I have to setup my recording profile again.
Any idea how to fix this? My GPUs a little old, but it should work with the NVENC encoder, shadowplay works perfectly and I think my GPU was one of the first to support it?
I currently have NVIDIA GeForce GTX 680 * 2 in SLI. GPU drivers are up to date on 382.05
Looking through the log pasted below I seem to be missing a few .dlls, not sure if they're vitally important for what I want to be using.
Any help?
