Finally the game is playable on my 3080, nearly doubled my FPS in places. Went from 60-80 to capping out at my monitors 100 in most places I just ran around to test.
Edit - still lowers in a few cities. But no where near as much
Today, NVIDIA is releasing a Resizable BAR profile for Starfield which increases performance on GeForce RTX 40 Series and GeForce RTX 30 Series desktop and laptop GPUs. In our testing scenario, GeForce RTX 40 Series desktop GPUs see on average a 5% increase in performance. The Starfield Resizable BAR update will be pushed via an Over-The-Air (OTA) update from NVIDIA and will be automatically applied for gamers running the latest Game Ready Driver (537.34) or the previous release (537.17).
Getting between 50 and 84 frames now. Used to be between 50 and 90. But I have only tested it in the city yet. Gotta wait for after work to actually play. I might be a bit obsessed with this game, spending my lunch updating nvidia drivers.
