Confirmed. Thank you. The latest Hotfix does seem to improve gameplay significantly.
Oddly, it seems to have also broken the Steam FPS Counter. In fact, that may have been broken in hotfix 22 or 23.
Regardless, it feels smooth and looks good at 4k / 60hz / Ultra. So that's fine with me. Plus I don't have to pay for Crossover now just to finish the game.
