Star Wolves III unplayable because of mouse lag

[PrivatePumpkin]

Hi,

my problem is stated in the name of the trhead. I simply can't play SW3 because of extreme mouse lag. If I move the mouse quickly, it often simply stops. I changed the DPI of my mouse, I changed the moue acceleration in the windows options, and I set SW3 into Win XP mode...but nothing works. I get roughly 130fps in the startp screen and in the tutorial mission. I never experienced such a problem in any game before.

Can anyone help me? I was so looking forward after I saw SW3 on Steam for 5€, because I love the first part and saw the interesting mods here in the forum.

thanks for any help.
