I have been using an intellimouse for a couple years now and pretty much happy with it.But one thing that bugs me is it isn't really all that smooth especially in 3d games.Using the drivers/software that came with it (3.10) I believe and ps2 rate adjuster.I can get the full 200hz out of the adjuster and it does help.I have tried many surface types but just cant seem to get it as smooth as I would like.It's almost like the mouse feet are a bit sticky but its the same even with a new one.Any thoughts on this?
