Nvidia still doesn't have Forceware 158 on its site, but Guru 3D got hold of a WHQL version and is happily distributing it since last Friday.
Geforce 7 users are officially still stuck with Forceware 90 or 93.71 to be precise, but we don’t see the reason why you shouldn't go to Guru3D and get this improved interface for your card.
The chaps at Guru3D warns the readers that despite the WHQL sticker, you should still consider this as beta. We hope to see the real WHQL probably with an updated number at nvidia.com as soon as possible.
The 32 bit driver is here while you can get the 64 bit one here.
