I have a Razer Diamondback 1600dpi & all other games run sweet including Crysis.
The mouse movement on this game is very jerky, up/down moves like quake1, if looking left/right in a car the mouse view centres to horizontal.
Have to play with sensitivity at 0/minimum, smoothness level makes no difference.
This game just hates the mouse!
I am wondering why the game says it requires 12GB of hard disk space on the back of the box, yet it's only taken up around 3-4GB on my hard drive?
Prefer the look of it to Crysis tbh, i think it looks fantastic.
Bit of an anticlimax tbh - i prefered crysis gfx and story line. It does however run very smoothly compared to crysis.
