Tested: Nvidia's Performance-Boosting GeForce 337.50 Driver
allow me to quote this from the article...
"All in all this is one of the most impressive driver releases we've seen in a long time. Nvidia's point to all this is to show that you don't need a new API and developer support in order to be able to get performance gains, but that time well spent optimizing drivers can make a big difference too. That said, competition from AMD's Mantle API likely pushed Nvidia to develop these optimizations. In the end, it's the gamers who win".
thanks AMD... bottom line, we, the consumers will always be happy once there is a "healthy competition"...
