Because in over 3y since I’m on Linux this is only a 2nd game I’ve bought which has some major issues at launch. I’m simply putting a warning for people here since many Lemmy users are also Linux users

As I’ve stated in my other comment, current workaround for me is to cap the game at 60FPS via Mangohud. That makes it playable just fine but my PC has much more performance to spare so there is something else going on besides “bad performance”.
