Yeah, looks like the 158.18 are WHQL now. I installed them just fine and can't really tell much different in games from the betas, but it's nice to see them making progress regardless.
Now I'm just waiting for new platform drivers for my nforce 4 board. I feel like the 15.00 still have more tuning and refinements needed. There is a leaked SATA driver floating around with a higher version number than what's included in the 15.00 package. I installed it and it makes a difference.
But things are most certianly coming along. 😀
