has launched new beta 310.64 drivers
for their video cards today. The new drivers gets you set for Far Cry 3, which I've heard a ton of good things about. Also, some configurations can get a boost in performance of up to 37.6%.
You can see some of NVIDIA's tests on Far Cry 3 using the 310.54 drivers compared to the new 310.64 ones on GTX 670, GTX 680, and GTX 690 cards.
