Very interesting - I just tried FPS limit 100 and Vsync off, and now I am able to use DLSS Quality (where before I could only use auto) - and it maintains a steady 100 FPS and the game is playable. If I turn DLSS off (with frame gen still on), the base framerate sits in the 80s, but I get the game-breaking choppiness. So it seems like, on my system at least, in order for frame gen to work, you need to set a frame cap that your machine can maintain with whatever settings you choose. As soon as you push the settings higher, where there is some variability in the frame rates, it becomes unplayably choppy.
