I recently sprung for a new mac pro, and after comparing to my windows gaming machine, the mac operating system seems to have a plethora of issues with the mouse. Not only is the acceleration curve oddly shaped (either the mouse moves at a crawl, or it speeds across the screen faster that I can follow it with my eyes, very little middle ground), but there seems to be a significant lag between moving the mouse and seeing the cursor move when compared to windows. Are there any programs which can completely eliminate the mouse acceleration on OS Lion? Is there a reason for the lag?
