I've had only three dodgy Linux gaming experiences in recent memory:
* Blade and Soul Neo: Didn't even get past the launcher. Probably anticheated to hell.
* Breath of Fire IV (GoG release). Works but doesn't map one of my gamepads correctly.
* Genshin Impact: Since some 5.x release, it works fine once it loads, but you have to turn off the network for 10 seconds during the load process.
Lutris is great even on a decidedly off-normal system (Void)
