Immediate top of the list fix needed:
-Always needing to compile shaders everytime you boot up the game.
Game's performance is so hard to gauge.
On a 3080 I can put it to 4K, Epic settings, DLSS quality, and turn on frame generation, and get 80 some fps, then it'll hitch all over the place to drop to 28, 47, 38. No rhyme or reason where or when. I was in the prologue area to get the location code in the bunker, and it was in the 20 some FPS, then a door opens at the end to the outside, and the whole area i've been in the last few minutes, is back to 60+ FPS, even though I haven't stepped outside yet? Super weird.
Tried to turn it down to 1440P, High settings on everything, DLSS balanced, frame gen on, and I'm now over 120FPS, but the same drops are eeeeeeverywhere.
I don't want to sit here, as I don't think anything exists, to hold a good visual and make it so I only hitch rarely. I also got a weird screen flicker from time to time, but the stuttering was making me actually sick so I had to stop playing.
I will say the invisible dude in the prologue was a nice fight, and the poltergeist on the ship was a cool touch. Lastly, the game in 4K on max settings really wasn't a looker, but that could be the prologue intro areas.
I may try again tomorrow with some other settings, but that's it for my initial try.
