@micr0 OBS itself? Just the usual stuff, with PipeWire window capture for the avatar and JACK (via PW) audio input for the audio (I do all my audio mixing/processing separately in Carla).
Stream machine is separate from my workstation and I just capture HDMI from it to show the desktop (or any other HDMI source like a Switch or a test machine's output, through an HDMI matrix).
