msi 9800 pro question

[aces170]

i have got a msi radeon 9800 pro.i installed doom3 demo,ut2k4 demo,prince of persia warrior within demo,nfsu with 4x AA and 8x AF everything is working fine at the highest setting possible in each of the game.i purchased ut2k4 full game and i changed the settings to highest possible.(one level higher than the demo).now when i play the game certain objects in the maps keep on disappearing and reappearing this does not happen in the demo version.
i also tried 3d mark 2005 and did not get any problems.
wat is the problem ?
i am using the latest omega drivers.(tried changing to win xp default but no difference)
my config is amd 64 3200 +,asus k8v,512 mb ddr ram win xp sp2

Does this happen to random objects or specific ones everytime?

Yes. Ive had this problem also. I had it with my oced gf3ti200. I'm not sure what was causing the problem, but i assumed it to be the overclock was a bit on the high side. I never got a chance to finish stabalizing the overclock because i got a 9800p to replace it so i'm just guessing it was the overclock. Is yours overclocked? If not, maybe the heatsink isnt on firmly enough. And as always, have a clean install of the latest drivers, as well as patch the game to its latest version. This was also the only game that gave me errors. And it was an odd error because it wasnt just that the objects were transparent, it was that they werent even being rendered. my frames would change dramatically when they would appear and then dissapear. If ud like i may be able to figure out what was causing this error and report my findings back to u. But follow what i said above, and see if those work first.

The card is not overclocked ever, also later I played UT2k4 demo with 16x AA and 8x AF with highest settings in the game ( They are a notch higher in the full game) and no probs there. I also ran 3d mark 2005 no probs there, ran doom 3 no probs there too. Ran the Counter strike source video stress no probs there.

What happens is when I move in the map I see grass and trees disappearing and re-appearing randomly could it be that my card is spoilt ?

And marsumane I really appreciate your help, can you report the findings back to me?
Thank you
