I just upgraded from an ancient laptop with XP, to a faster machine with windows 7 and found that my game's mouse input is all messed up.
I can't quite pin down why, but small movements seem to not get picked up at all, and medium movements seem absolutely huge.
I'm using a 1 update per frame method, but I'm processing the mouse inputs with respect to the delta time each frame, before I pump the movements into my physics system. This worked across all previous XP setups I tried, even those with vastly different system speeds.
If I turn off the mouse acceleration in Win7 ("enhance pointer precision"), it returns to almost exactly the behaviour I had with XP.
Is there a way to read mouse info before OS acceleration is applied?
How do people here handle mouse input that works across different setups?
Cheers,
