Mouse Delay

Has anyone else had problems with mouse lag/delay? When I'm playing I pretty much constantly have mouse lag, and it makes the game unplayable.

I've got a Razer Copperhead and mouse acceleration in Vista is turned off. Triple buffering is also turned off via my nVidia panel.

Any ideas on how to fix this?

The only way I was able to even get the CopperHead close to playable was to limit my FPS to around 30. Forcing the higest AA you can in the control pannel should do the job.
Thats probably not what you wanted to hear, but so far we know of no other way.
