The game looks absolutely amazing on an AMD GPU, without realtime raytracing.

Several years ago now, I managed to get it to 4k90fps on a 6900XT, with basically all settings on ultra/psycho via some ini tweaks, custom FSR values, just no ray tracing, using ‘old school’ cube maps and light sources and what not.

And that was all running in Proton, on linux, as well.

Nvidia absolutely barged in and said hey guys guess what, we completely obliteraterated the entire history of how lighting works in game engines, here’s our new extremely pretty but extremely, astoundingly inefficient lighting engine, rewrite your entire game engine and game to make it work on your custom engine that’s been cooking for 10 years without any notion of this new lighting paradigm.

EDIT: I should add that that is 90 ‘real’ fps, no frame gen, just early FSR.
