So I don't game a lot and I'm not sure what that car driving game is, but I noticed at ~1:30 his left thumb is moving all over the place and the car keeps driving in a straight line? It doesn't seem like any of his hand/finger movements match what's on the screen, am I crazy?
I had never heard of it either. I had PIA when I was on Windows, still haven't gotten it setup on Linux though.
