weird-ass glitch.

that's my problem. After I move my charachter or rotate the camera, things freak out on any set of video settings. If i do an auto detect it puts most everything pretty high, and it'll display fine so long as i don't move. (other charachters walking around onscreen doesn't initiate it, only my movement.)
there's no lag, just that trippy little freak out there.

as far as i know i've got a pretty decent build:

asus p5b mobo
intel core 2 extreme
(bfg) nvidia geforce 7900 gs (256)
2 gigs of ram.

she runs half life 2 fine on highest settings (i havent tried with anything higher than 2 AA, but everything else is maxed)

also, i'm running on vista rc1 if that makes a difference.

thanks in advance, and if there's anything else i should tell you, just let me know.

Your computer is realy good so you don t need to worry about that.I think that your problem is driver for graphic card on vista.
I am not 100% sure but i think that is the problem.
The solution is that you try to get other driver and try

that graphic is due to overheating on your graphics card atleast the was the situation for me it helps
