NVIDIA released their GeForce 320.49 drivers last week, but they arrived in beta form. This week, though, NVIDIA have released them yet again, but have donned them with the WHQL stamp of stability.
We have the usual bug fixes and performance games with a 5-10% increase in performance for Metro: Last Night, Assassin's Creed 3, Starcraft 2 and BioShock: Infinite. A bigger 17-20% jump is given to Dirt and Tomb Raider. Artifacting issues in Battlefield 3 should be fixed, and EvE Retribution and Assassins Creed 3 should also be fixed up no.
The dual-monitor problems that saw GPU's running at higher performance levels has been fixed, so has the issue with GeForce GTX 680M-based notebooks going black after enabling SLI or 3D. You can grab the GeForce 320.49 WHQL drivers here.
