Okay. The NVidia driver update (v 257.21 WHQL) fixed the black screenshot issue. But it introduced a new bug: Corrugated Textures:
Any vertical surface in WoW gets corrugated like this. And the lines converge and diverge when I move and it’s VERY annoying.
A shadow being cast on the vertical surface introduces a clip of one corrugation (the shadow) on top of and through the plane of the texture corrugation lines. It makes the walls in Valiance Keep look terrible.
What setting do I need to frob to get the corrugated texture problem solved? I don’t want to roll back my driver version because then I can’t take screenshots anymore.
WoW Game Glitch: No Ground in Stormwind
This one’s not the fault of NVidia graphics drivers but of WoW itself:
(in the Canals, toward Cathedral Square from the Harbor)
The floor disappears and you can see building exteriors where they don’t belong.
I already reported this bug to Blizzard via the in-game bugreport system.
