I have a MSI R4870 T2DIG (4870 1GB) I just purchased from newegg about 2 weeks ago. Everything is working great until I decided to play Crysis. Randomly while playing, usually between 45m-1hour the game will just crash to a green screen with black vertical bars or just a black screen and I have to power off my PC. I've checked the temperatures and it isn't overheating, it idles at 59* C and under a load reaches 75* C (confirmed while playing Crysis for about an hour and checking GPU-Z logs and the peak temperature reached was 75* C). I've heard the problem seems to be an issue with the 4000 series bios trying to switch to powersave mode causing the card to not respond and crash. My problem is, I'm not sure if this just an issue with Crysis or if this will occur with other games. I've played DMC4 for a few hours with no issues, so far it is only Crysis and Crysis Warhead that has the problem. So I need help deciding if I should just RMA the card and get something else or is it just Crysis causing this? Any help on the situation will be appreciated, maybe someone else has had this problem and found a fix? I heard about the riva tuner fix but I refuse to own something that I need a 3rd party software to have function correctly. EDIT: I've tried uninstalling and reinstalling drivers already before that is suggested. Currently using 9.1 on Vista X64.
