So I have a headless server and use xrdp to connect to the system. I tried running OBS both using the apt install and flatpak way but both show llvmpipe instead of the Nvidia driver being used in the logs which results in high CPU usage and frame drops obviously.
OBS logs show:

Not really sure what to test anymore as it seems that everything “should” be fine but it’s not.
