Have you tried fiddling with the in-game mouse sensitivity settings? Also, try changing the settings in controls to Analogue instead of Digital.
I can't find anywhere in the game to switch from digital to whatever. The mouse works fine on all of the other games but does show signs of instability at times. How would you adjust the Logitec mouse for analouge and digital?
Sounds like a mouse driver issue. Have you upgraded to the latest mouse driver? Logitech and Microsoft recently announced new updated mouse drivers.
Where would you go to download the new Logitec mouse drivers? I don't have a clue as to where this is.
Options, Controls, Fight Type is where you can change from digital to analogue - it doesn't do anything with the mouse driver afaik, it changes how the game processes input.
The mouse sensitivity slider is just above fight type.
Are you using the Logitech driver or the generic MS driver for your mouse?
Since I just plugged in the mouse and started using it, I am using the generic drivers I would say. I have never downloaded any mouse drivers for the Logitec and everytime I try, they want you to down load a program, then register and pay for that driver plus several others which are supposedly outdated.
