Well, I was running the most current, 4.1 driver, i think is what it was from the ati website, but was having problems with NFS underground freezing. So I went back to the driver that came on the cd, 6.14.10.6444. I didnt have the freezing trouble until I updated to the 4.1 driver. I tried reducing all the settings and it still froze while playing. I have been reading where it suggest turning off the AA and AF features, but cant find where to turn them off. I did find where I could reduce them both to 2x, so I did that. Also turned off VPU recover and error report, read where that may help. I have never had an ati card and dont know much about setting it up, so any help would be great. I also read where the 2590 beta omega drivers work well, but havent tried them.
