We can confirm that Nvidia's 177.39, the driver that is supposed to speed up things, will get 3Dmark Vantage to run 10 to 15 percent faster.
It is still to be confirmed if the driver can accelerate games at this healthy rate, but we might have an answer very soon.
This driver should even get the games faster, and judging from its name we are talking about a GTX 200 generation driver that won’t support Geforce 9 or older products.
Nvidia has abandoned the Unified driver ship, probably due to marchitecture differences, but Geforce 8, 9 and GT200 series looks quite similar to us, the same concept just improved on the new cards.
