Hmm... are you referring only to the controller or also the keyboard?
I use a controller wired to my laptop. I'll try it with a keyboard too later.
Hey sorry for the late reply. As far as I can tell it works perfectly with a keyboard, but the controller tends to be a bit unresponsive when trying to turn.
My brother now has a PC running Linux Mint, he tried the game with two different gamepads and didn't experience any kind of lag.
