Bug Report OBS and Optimus - Quicksync Audio Desync

[n3v3rm1nd]

Hello there !

OBS with Optimus is pretty much broken. The only way to use it wiht QuicSync is to add it via NVIDIA Settings to launch it with the Nvidia card. When i right click it this way my only option is NVenc.

When using Quicksync i have a small audio delay. I dont know why or if it appeared suddenly but nvenc is clear. Newest drivers are installed. Any ideas ?

We know about this and we're testing fixes at the moment.

okay great ! 0.625b still has this issue if its important

Yea, I thought I may have fixed it in 0.625b, but it appears not to be the case. I may have to ask palana to investigate.

[n3v3rm1nd]

will this be still fixed ? i have to use nvenc for now because auf the audio delay,but its putting more stress on my GPU and since i am on a notebook heat is a issue ... please fix it

EDIT ---

So a syncshft of 145 +-5 seeeeeems to work out pretty well but please fix that it will be exact! thanks :D
