Mouse acceleration

in order to resolve mouse motion problems with SDL and w32, i must disable
the windows mouse acceleration but i don’t know how i can do this with a C++
command
thanks

Hi all, can someone describe a simple method in SDL (when in full screen
mode, I guess) to accelerate or judge the speed of the mouse.

It seems that on one machine my mouse is quite sluggish in my app, whilst on
another it moves perfectly adequately.

Any takers?

Hi,

Perhaps you could time the events per second and compare. Acceleration
could be calculated by the delta change, so the scalar of the delta
vector (hypotenuse); if that is what you are looking for?

It’s probably that the low level input driver isn’t doing the normal scaling
of mouse delta values that you get in windowed applications. What platform
are you running on?

Hi Sam.
I’m running under Windows 2000 using a Microsoft intellimouse. Um … I
seem to have been polluting the mailing list with these mouse posts, all
with slightly different titles. I’ll stop now.> ----- Original Message -----
