I've been waiting patiently for any update on this but still no post on it..
1) Lag on first time clash. - really annoying
2) the game freezes and you can't do anything but reboot your pc.. and this only happens when I play diablo 3... i really don't understand why this happens. i tried reformating my pc thinking a clean installation of everything might help but it did not .. .. . just had to reboot earlier before i posted this since it froze my pc......
oh, btw, i also had the latest drivers for the gtx 260 installed after reformatting my pc.
Core i7 with GTX 260 video card
