what you mean with “smooth” ?.. I assume, as a lot of users, you mean with DLSS 3 the new nvidia Frame-Generation feature ?
Ah… and seems… you speak about:
So please described a bit more about the issue. Did you still get “doubled FPS” with Frame-Generation on ? Whats your system-settings and game-settings which may have an impact: as example Vsync on/ off , etc.
