Playing on my PinePhone Pro on ArchLinux using Backbone One controller. Some missions are super hard because the game does not have any aim heper for gamepads. The game runs mostly smooth, but sometimes I experience small yet noticeable FPS drops depending on the weather and time of day.
Is the pro fairly powerful? I have the non-pro and it can barely handle running the os. Edit: damn that's a pricy controller.
Unpopular opinion: non-pro can handle the OS just fine and then some. Try out SailfishOS (unfortunately not OSS) - it's as smooth as butter. Or UBPorts - it works great (unfortunately both Sailfish and UBPorts aren't as polished when it comes to actual hardware support on PinePhone, but they show nicely what could be done). I don't think I even need to mention Sxmo, which is no surprise that it works great, but its approach is definitely not for everyone.
It's just Gnome/Plasma that are mainly developed for "big" computers and are pretty wasteful. But the situation is definitely improving.
I have sxmo on it currently but I haven't been using it much. I was exaggerating a bit, but it is just slow/choppy enough that I can't do my typical web research comfortably
