I just purchased HD 3870 OC from Best Buy. I have a dual boot system with XP.
Now my problem: My favorite game is an older Nascar racing game from 1999(Nascar Heat).

After installing the card and drivers, I fired up the game(in Vista), the first thing I noticed is an increase in FPS(yeah),
but then parts of the cars would appear and disappear(boo).

I then booted over to XP and installed the drivers, fired up the game and everything is great.
Increased FPS and the cars look great.

Went back to Vista, cleaned the drivers out (several times), installed every driver from 8.3 to 8.6.
Always the same problem, car parts appearing and disappearing,

Anybody have any ideas why this is happening?

Before anybody asks, the card before this was a 8600GT and had no problems except lower
FPS.

This card was a bargain at $128.12 inc tax, that's why I bought it!!
 
Vista doesn't like older games.

I often have to boot Xp specifically to play older stuff like Kotor I.
 
I can play the game fine with Nvidia cards, I am using a 8600GT right now in Vista. I suspect it is something with the ATI drivers.
 
ATI hasn't optimized for every old game. They try to optimize for the newer ones.
 
From what I've been reading, I believe it has to do with drivers having backward compatibility with DX 7,8. Apparently Nvidia has done a better job with this.

I was hoping somebody else who had this card was playing older games and could comment on there experience.
 
I play a few old games myself w/a ATI 3870 and vista 64 and no problems at all using CCC 8.5. But to be fair, not the game your talking about. BUT....

I did have a few problems with a couple older games and this fixed it:
Go to MS download site and download the DX9 updater and update all your dx9 files.

Yes, vista uses DX10, but it emulates DX9 ... updating files for dx9 fixed problems I had with older games. Hope this helps :)
