I just built a new system with Windows Vista 32 bit, Phenom 9600, and a HD 4850 graphics card. I was all excited to start gaming but I've run into quite a few problems that seem video card related, but they might not me. First all of the games are stuttering quite a bit. I was playing UT3 and Stalker and they both run fine (100 or so FPS), but they often dip so low that the game stutters. I can't figure out what the problem is. The other strange one that might be related is that both games freeze when I hold the shift key down and they resume when I let go of the button. I can't figure out why. Any thoughts?

i would have thought the shift button affects something in the background when it is pressed, is it mapped to any functions in a background program?

stuttering sounds like hardrive access a defrag could help.

I'm using 8.6 drivers. I'll try defraging the hard drive to see if I can eliminate the stuttering.

I think I figured out the shift problem. My keyboard repeat rate in vista was set too high. It just froze the computer any time a key was held down. I noted it when i held down left to move in my post and it froze the computer as well.

Use the Hotfix drivers, direct install, Catalyst 8.6 is NOT optimal for the 4850. Also, a new install of Vista spends a couple of days indexing all the files on the system, that would probably be causing the stuttering, along with those wrong drivers.
