game auto-sets to ultra graphics, but can't run that at/above 30fps. setting to balanced settings and changing steam deck screen to 40hz results in a smooth experience and doesn't look terrible (with FSR off). Can reach 60fps at low settings (with FSR off, so there's a bit of wiggle room) but it doesn't look as good, specifically shadows. in-game vsync seems broken, so just turn that off and limit fps with steam deck, otherwise frame pacing is kind of all over the place. I think a typical linux gamer would enjoy this without tinkering, assuming his hardware is good enough, but maybe that question shouldn't be specific to just linux when I'm reporting as a steam deck user. changing settings is a must on steam deck.
