Default Re: Artifacts in Batman's Arkham Asylum are driving me insane!

OK an update.

Running SLI GTX 295 on Crisis Warhead i'm runnng up to 91 C, with no artifacts.

If i run PhysX on Arkham on the GTX 295 i get artifacts too (but much slower framerate)

If i run PhysX in software (enabled as High but switch off in NVidia CP) i get no artfacts but its dog slow.

So something about PhysX on GPU is causing the artifacts.

At one point i noticed the artifacts almost emanating from a hanging banner which appears only when PhysX is enabled, suggesting the geometry of the banner is determined by the PhysX card and this data had got corrupt somehow. So maybe they aren't "visual" artifacts in the usual sense but corrupt geometry data?

So this tells me hardware PhysX drivers are either buggy or there's an issue with the power profile when you enable PhysX.

Any suggestions welcome ...
