Other than the issue with drivers after 22.5.1 I've had no problems with my 6800. It's happy enough with the game at 4K 60Hz, if using ultra settings then to achieve 60FPS in the location in the spoilered image requires FSR 1.0 / Ultra Quality. Without using FSR, Update 12 gives c. 43FPS in this location (not the specific station but the position in the station, which I use for easy repeatability for framerate comparison between updates).
Performance at these settings in Odyssey settlements suffers a bit - but not so much as to make it unplayable (for me at least).
