A prominent open-source dev publishes their findings as to what's going on with Starfield's performance, and it's pretty darn strange.
According to Hans-Kristian Arntzen, a prominent open-source developer working on Vkd3d, a DirectX 12 to Vulkan translation layer, Starfield is not interacting properly with graphics card drivers.
I've had 1 full crash, and a good handful of NPCs running into walls or levitating through ceilings.
Performance is fine, I guess, but I got the game as part of a promotion while upgrading my graphics card so it had better be. I believe folks who say it runs like dog on hardware that's only a couple years old. It's apparently unplayable if installed on a hard disk instead of an SSD.
All in, it's the smoothest Bethesda launch I've ever seen (I skipped fallout 4, maybe it was better IDK) but that's honestly not saying much. It's way better than cyberpunk was at launch.
Once every 20 or so times that I leave my inventory, my viewcone is placed inside of my weapon for half a second and then the game stutters and I pop back into my character's head (I think the inventory screen may scale up weapons for display and it's failing to undo that so quickly, but that may be completely false).
That, and one dialogue "loaded" instantly (it started the interaction but wasn't prepared with the graphics) and displayed a black screen for the first half of the conversation. Oh, also, FSR is FSR and makes spaceship landings look terrible.
Those are the only notable graphics issues I've experienced aside from widespread poor performance, and they might not even be graphics issues. I mean, the game doesn't run too great, but the core gameplay is definitely less buggy than FO4 or Skyrim at launch. I'm sad to hear people are having more serious graphical issues, especially Arc users.
