Is OBS fullscreen preview lossless and a direct projection of the game?
Anyway, for those who have been trying to do 144hz gaming with 60hz capture without latency, I'll repost the following final settings.
GTX 1080 > Display Port 144hz Gsync Monitor
GTX 1080 > HDMI output to HDMI input on HD60pro in 2nd PC.
At this point, fire up the Elgato Game Capture Software.
Now in the gaming computer, extend the desktop to the Elgato device.
Once you do this, on your live preview in the Elgato Game Capture software you should see your extended desktop.
If you can see it, then tell OBS to do game capture, and project a fullscreen preview on the Elgato monitor.
This should theoretically allow you to game 144hz exclusive fullscreen and prevent any gsync/vsync/144hz to 60hz tearing on your capture.
