Hmmm..Can't say that it has really been a problem for me. I allways just speed up or slow down mouse sensitivity within the game(advanced controls or just under controls) to my prefered taste. With the Half-life series, I allways had to speed it up..With NOLF2, Max Payne, QuakeIII, I had to slow it down or it just spun around waaayyy too fast. This is with XP, SP1, and Logitech Optical mouse.
BTW..I just noticed that I do not have the option to set pointer acceleration(no biggie to me) and "enhance pointer precision" is checked. Also, I do not use Logitechs' mouse drivers. I feel they add jitteriness when scrolling. Hope this info can help anyone..
Later..
