Thanks for the heads up!
After seeing the Nvidia update on MS update (I don't install H/W drivers from MS, I go to the Mfg site and D/L them from there), I went to Nvidia's driver forum and saw that lots of people were having issues with the 310.90 driver and decided to wait until a new driver was issued.
I just went to the driver forum page and saw this:
"The new NVIDIA GeForce 314.07 WHQL display driver is now available to download. An essential update for gamers jumping into Crysis 3 this week, 314.07 WHQL improves single-GPU and multi-GPU performance in Cryteks sci-fi shooter by up to 65%. This driver also brings sizable improvements in performance in several other popular titles. For more information on this driver release, please visit:
This driver package supports GeForce 8, 9, 100, 200, 300, 400, 500 and 600-series desktop/notebook GPUs."
This driver shows when I use the driver search page and choose my GX465 GPU.
