I've driving around briefly in FH5 just to test performance.
The 3080Ti is nuts.
Epic settings for everything, no resolution scaling etc. 5120x1440 runs at a locked 60 with around 50% GPU utilisation and, unlocked, runs around 90 with vsync at 97% GPU utilisation.
Sweet.
Have you given it a try using keyboard controls, or are you waiting? If so what's it like?
