I get these errors on some buildings. They appear on some triangles.

I think I can recall getting that too, for buildings in the distance. It is minor, but for taking screenshots or what not, I suppose it is an annoyance

Maybe related to your ATI AA mod?

Otherwise try another driver.
If that doesn´t help it might be an overheating video core which can produce this checker pattern as well.

It could be overhaeting/damage due to some overclocking.

Update:

Yes my card finally died.

lol

Classic thread

Hi!

I'm back.

My current ATI card also has the same problem.

OPK was right, it only occurs when I turn on adaptive AA.

However now it can be enabled in the drivers without poking around in the registry.

I use Catalyst 6.5 and an X800XL.


P.S.
My old card was an ATI 9800Pro.
