Mouse speeding up/slowing in games

[dovey]

Hi all, Having a bit of a problem in cod 4 and left for dead on the laptop. The mouse will work normally but randomly move very fast. Say a mouse movement normalls takes me 30 degree to the left it would suddenly take me 180 degrees which makes it really hard to play. Not sure if this ties in with a certain amount of fps or a fps drop.

Left for dead does this where and the mouse also appears to move in blocks (as well as fast/normal) but turning of multi core rendering sorts the problem, cod 4 however does not have such an option. It's only a recent thing too as left for dead has worked fine before now. Anyone had a similar problem or have any ideas?

All my drivers are the latest around. thanks

ive had similar problems with a logitech mouse...disabling game detection and leaving only 1 possible mouse sensitivity did the trick.

otherwise it caused hell when i used to play online fps.

if it still keeps happening try turning off hardware acceleration in your windows mouse settings? i dont see why modern mouse really need it anyway
