I'll let the screen shots speak for their selves. Been having these weird glitches since I got prey from Steam on the weekend. I can't work out what it is that it's trying to render that's causing them.

My specs are:
Vista x64
x2 4400
x1900 xt
2 gig of ram
dfi nf4 ultra-d

I also updated my graphics card drivers recently, but I know this doesn't have anything to do with it as I had the same problem with Doom 3 ages ago on this system.

I've tried it at stock clocks and it's not making a difference.

Any one got any ideas?

edit: All my other games are fine.

Temps are fine. Graphics card hardly has a chance to get warm and all my other games play fine.

Have you ever played Quake 4 or Doom 3, just wondering because they use the same engine so wonder if you get same effects? (so that would make sense)

EDIT] There seems to be problems with some latest graphic drivers with this game, so what catalyst drivers are you using?

As I say I remember having the same problem with Doom 3 ages ago.

I'm using the latest Cats from the ATI/AMD site.

I just noticed now, if I turn off shadows the problem goes away.

edit: Got a link to the issues you mentioned?

Try some older drivers.

I don't see much point in this as I had the same problem with Doom 3 like 6 months ago. Don't like the idea of getting drivers older than that.

edit:

I'm willing to accept that it's a driver issue, but I'd rather see an example of someone else complaining about the same thing before I go that far back.

I had this problem with my 9800 pro and Doom3 yonks ago... a few months later it died due to ram failure. I suggest you get in contact with ATI.
 
I'd give driver cleaner pro a try (run it from safe mode and delete all ATI related files), after uninstalling your drivers. I'd be surprised if it was a faulty card since it's fine with other games. Both Prey and Doom 3 are OpenGL so maybe you have some dodgy OpenGL dlls hanging round on your PC or some old OpenGL drivers.

Failing all else, fresh OS install will give you a definite answer.

I think I'm going to with this option. There's nothing wrong with the card, I'm 100% on that.

Lol the screenshots show other wise!

A note on overclocking: it is very likely that overclocked configurations that "play everything else perfectly" will start to show problems on D3 due to new usage patterns. Everyone is of course free to do whatever they want with their own hardware, but don't complain to us...

im not sure if you have overclocked or not. But i dare you try and lower your clock speed a few mhz and I bet it clears the problem right up.
 
Out of curiosity try HL2 - lost cost with HDR enabled if you get the chance, the same problems displayed themselves with that too on my 9800
 
Fixed it guys, turns out you have to have Catalyst AI Off for Doom 3 engine games.

Good job I found out when I did as I was just about to format :p
