Little while since I posted but I thort this was important. I got Halo 2 from work today, and installed it. Everything went fine, was slighty surprised with the online activation but hey! Got into the game and it looked like my mouse was being run over a bed (or somthing as uneven). When ever you move the mouse it seems like it just stops, almost like the optical eye isn’t reading the surface right. I had a play with settings but couldn’t fix it. It’s JUST about playable (for me atleast). After about 1/2 hour poking about on Google I found a ‘select’ few people with the same problem. We all have GeForce 8800 GTX’s. It seems to be a driver issue, which I HOPE it is fixed soon. I did update my GFX drivers to the latest, but it hasn’t be resolved yet.
So if you have a GeForce 8800 GTX, hold off buying Halo 2 till this issue is fixed.
