That’s really bizarre, I can reproduce it reliably - if I have it on 240hz, it’s definitely slower (and it also skips on occasion) - if I set it to 60hz, it’s faster, and doesn’t exhibit the skipping behaviour. I’m just playing with whatever the default web page viewport is.
Thanks for that detail! It seems it is indeed tied to framerate after all but inversely.. I’m using the frame delta but my rotate function runs in the FixedUpdate, ouch. So in your case the delta is very small but the update still runs at 64Hz (the default rate). Not sure why I’ve put it in Fixed to begin with but I’ll unfix this when we can update the game, thanks!
