Nvidia has been hard at work in order to make the life of a Linux gamer much easier and it appears that Valve and "some other developers", in addition Nvidia of course, are to blame for impressive overall performance improvement with the new R310 Linux driver.

The new R310 driver is made for the latest Geforce 600 series graphics cards but supports previous generations as well. Valve's vice president of marketing noted that Nvidia managed to increase the overall gaming performance under Linux with this driver that took an unquestioned leadership position in developing R310 drivers to provide an absolutely unequaled solution for Linux gamers.
