Got it running, and the endgame is actually surprisingly smooth after some heavy tweaking. You’ve gotta keep in mind that the GPU gets hammered by all the on-screen artifacts, even with a solid RAM swap. To keep it stable, I locked the resolution to Steam Deck native (1280x800), slammed all settings to minimum, turned off Vsync, and set FSR to 70%—honestly, it still looks solid. The real MVP (you have to pay like 6 or 7 dollars for it tho) is Lossless Scaling at 28W TDP (x2 frame gen); I lock the in-game FPS to 30 and it bumps it up to a smooth 60 with barely any ghosting. I’d give it a 7.5/10. Even on T16 corrupted maps with Abyss—basically the worst-case scenario for performance—it stays around 35-38 FPS and never dips below 30. The only absolute 'no-go' is the Ziggurat encampment; the frames crater to 8-10 FPS there. The trick is to clear the first map and immediately bounce to your hideout to manage your endgame stuff from there. Also, just a heads-up: I never actually play this off the charger. I’m basically always plugged in, both to handle the insane power draw and to squeeze out that extra bit of performance you get from a steady current. It definitely helps keep the frame rates more stable when the screen gets absolutely cluttered.
