It’s technically possible to triple or even quadruple the framerate, but the performance overhead will grow, and the game logic will still run at the original framerate, causing inputs to still have the same delay.

The October 13 version has been amazing, hope to see this mature more and possibly allow it to function during high visual changes (looking around quickly). I’ve been running it permanently on Starfield and can’t go back
