Nvidia released WHQL 320.49 drivers for desktops and notebooks

The newer 320.49 drivers are released by Nvidia for Window 7 and 8 for both desktops and notebook GPUs. Nvidia also included drivers for Windows XP and Vista.

Nvidia stated that the 320.49 drivers have fixed issues that were reported in 320.18 drivers, though Nvidia didn’t say nor acknowledged about the artifacts and stuttering issues with certain cards (in random) and eventually killing the GPUs. The reports kept on piling, but looking at the system configuration and the make of the card that had shown the issue/damage it was very difficult to roughly point out how is this happening? Only way to find out whether or not this issue is fixed, is by the good old fashioned way- doing it yourself!

But on the bright side, though Nvidia made a vague acknowledgement that the newer drivers fixed flaws that 320.18 had and maybe Nvidia did fix it.

Nvidia also added support for OpenGL 4.3 for GeForce 400 series and later GPUs and DisplayPort 1.2 support for GTX 600 series.
