Mouse tweaks for the horrendous mouse code in this game?

Anyone have any other tweaks that prevent the horrible negative acceleration when using high end gaming mice, BESIDES the already known 125hz polling rate tweak (which works but causes mouse turning to feel like you're playing at 50 FPS instead of 200?)

Is there any way to get the super smooth mouse turning that you get with 500hz and 1000hz polling rates, without the rediculous pos/neg acceleration and the wavy lines when trying to aim in a straight line?

I can aim a lot better in AVA, thanks to the perfect mouse control (from the UT3 engine) and ZERO--absolutely ZERO negative or positive acceleration. But CF...feels like I'm using molasses as a mouse surface...or cat vomit...

Getting 200 FPS helps, but 125hz is just fail when you have a Deathadder Black....
