792p? Man I am kinda worried for GTA6
GTA6 runs on Rage. so it should be fine.
the precise issue with UE5 is that devs use its features as shortcuts. instead of having good looking baked GI, they just throw Lumen on it and leave it.
UE5's Lumen is so insanely awful, it's really hard to hammer home just how bad it is. it looks worse than literally all of the competition's RT implementations, while also running worse.
there's a guy who remade the first few level of the PS1 Toy Story 2 game in UE5.
and at first he used Lumen, and because Lumen is so unstable he also was forced to use TAA to smear it in order for it to look cohesive.
but as he was finishing the project and polishing it, he decided to turn Lumen off and just bake the lighting instead. it increased his performance by an insane amount, and allowed him to turn off TAA, which made the game look 10x better while boosting performance from 1080p 25fps on high, to 1440p 70+fps on max settings...
that's what Lunen does to a game. it makes it look blurry and unstable, while absolutely destroying performance.
and that's exactly what you see in High on Life 2, and basically in every single game that uses Lumen.
Lumen literally makes games look worse, while reducing performance sometimes by 75% or more.
