Only initial thoughts are why in their right mind are they using windows on a handheld device
Windows because it will cost Framework or whoever it is a lot to do it Valve style - coming out with your own distro, support it and yeah the proton issue. If it will run only Linux games, that market will be minuscule.
how is that modular? it’s all one piece except for the controller. congratulations, you have a console.
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?
