This is the latest leaked ForceWare Driver. I have to warn you, it seems real buggy for a lot of people. Probably not worth even the hassle, although the new layout is fun to look at for sure.
The drivers originate from OSNN.net who seem to have released them 66.81 ! Anyway, I recompressed the archive towards 10 MB (saving 8 mb) and a setup.exe is included.
All graphics cards are supported and the files are dated at the 9th of October.
This driver is beta and not supported by NVIDIA!
