Last week we saw NVIDIA's GeForce 320.49 beta driver and now the company rolls out the 320.49 WHQL release. You can find it over here. Be aware though that some users complain the 320.49 driver causes issues with crashing and freezing, so you may want to wait a bit for the next driver release from NVIDIA.
This is the launch driver for the newly released GeForce GTX 760.
GeForce 320.49 drivers include several fixes for issues reported with 320.18 drivers. Refer to the release notes for a full list of fixed issues.
