As I suspected the screen shot looks fine. I would imagine that when capturing the shot a separate render target is used? It doesnt look like garbage triangles, it looks more like corrupted texture memory. Its not like a consistant pattern over the whole screen, each rendered element seems to have its own corrupted characteristic.
I have plenty of other games that run just fine so I dont think this is a faulty hardware issue.
Anything else that I can provide? Is there an email address I could send my dxdiag.txt to?
Its not like I am a disgruntled customer as I havent purchased it. But it sounded like a cool game so I am at least a potential customer.
