Here is yet another chance to increase your framerate and/or your game texture quality. The most prominate feature is better SLI AA support (it's easier to enable), instructions for enabling it are below (taken from here. (
http://www.nvidia.com/object/winxp_2k_78.01.html))
Step 1. If you already have Coolbits installed, you can skip to Step 2. Otherwise, click on your Start Menu in the Windows Task Bar and select Run. When the command box opens, type "regedit" (without the quotes) and press OK. With the registry editor open (shown below), go to HKEY_LOCAL_MACHINE \SOFTWARE \NVIDIA Corporation \Global \NVTweak (expand the menu using the "+" expansion buttons to locate this menu item). Click on "NVTweak" in the menu. Next, right-click on the empty space inside right window and choose "New>DWORD value". Name the value "Coolbits" (without the quotes).
Step 2. Within the Registry Editor, right click on Coolbits and choose Modify. Change the Value data to "8" (without the quotes) and click OK. Exit the Registry Editor.
Step 3. In the NVIDIA Display Control Panel under Performance & Quality Settings, you now have the option within Advanced Settings to change the SLI rendering mode to "SLI Antialiasing".
Step 4. Once you select and apply the SLI Antialiasing mode (either globally or for a specific game profile), you then have the option to select either SLI8x or SLI16x under 'Antialiasing settings'.
Step 5. Select the desired antialiasing setting and click "Apply". SLI Antialiasing is now ready for use!
Now some of the computer-savvy reading this may be thinking that SLI AA was available in the last driver release, you're right, but only for certain cards, this version works for all cards. The quality of the game is improved vastly (particularly the textures and lighting, metals look far brighter for instance), but only when you look closely can you notice the how smooth the drawn-in shadows are.
The overclocking features are improved a lot as well, automatic-OCing in this release gets you maybe 10-20 mhz. And before someone says anything, I know these drivers have been official since mid-August, but since no one's mentioned it I thought I'd bring it up :)
***Edit***
I almost forgot about this thread... anyway, the new version has nothing new unless you have a GeForce 6500, however I'm finding they make 7-series based systems slightly less stable...
