Its a driver issue because it was fixed with a simple driver update, not a hardware update. Now if you're saying it's a hardware issue with a driver workaround, then maybe.

Chris, we're talking about the R600's poor performance with Adaptive AA modes in previous drivers that seems to have been fixed in the Cat 7.8. I've heard that it might be because Adaptive AA(full compression) can be resolved in the ROPs, but was previously not. The new driver supposedly moves Adaptive AA resolve back onto the ROP's which increased performance dramatically.
