Mine says "Driver Version: 9.18.13.697"
This means (is the same as) NVIDIA GeForce Driver version 306.97 which is the current non-beta driver. Note the encoding between the version as reported by Windows and the actual driver version as released by NVIDIA --- 9.18.13.697 >>> 306.97
NEVER under any circumstances should you use Windows Update to update an NVIDIA video driver. Go here instead and specify the card and OS you're installing the driver to and it will give you the correct driver to download.

The current NVIDIA beta driver is 310.70. This will change frequently, so depending on when you read this, it may be different already. DO NOT install it unless you feel like riding the bleeding edge of that razor. Not worth it in my opinion.
Once installed, check the PhysX Driver.
Start > Search "NVIDIA" > click on NVIDIA Control Panel > Help > System Information > Components tab
PhysX entry should show 09.12.0613 or higher. If not, get it here - http://www.nvidia.co...613-driver.html
I am running this PhysX Driver on top of the 306.97 NVIDIA GeForce driver and the visuals in COD5 are absolutely stunning! It is much better than the PhysX Driver that came with the 306.97 driver package. Installing the .0613 PhysX Driver will replace the existing driver. Just follow the prompts...
Once the PhysX Driver has been updated or verified to be at least .063, go back into the NVIDIA Control Panel and under 3D Settings, click "Configure Surround, PhysX" and verify that the Processor drop down has been set to "Auto-select (recommended)" Mine was originally set to "CPU" which is just plain wrong. Once I changed it to Auto-select, the text below that drop-down list changed to read "PhysX > GeForce GTX 660 Ti" Of course, yours should read the name of your card. But if "Auto-select" does not trigger the PhysX Driver to use the graphics card, I would force it using the name of your card on the drop-down list.
NOTE: Current PhysX Driver is version 09.12.1031 which is available here - http://www.nvidia.co...031-driver.html
I am not running this driver, but may test it just for kicks.
Hope this helps.
