I recommend trying the "modified" Quadro driver because it provides superior performance for most people who have GeForce cards (it most certainly helped my performance).
The installation process is slightly different, but still very easy. Here's how:
- Delete the C:\\NVIDIA folder (it's a temporary folder). This step is critical, so please don't skip it.
- Download the Quadro driver for 64-bit Vista/7 from here: http://us.download.nvidia.com/Window...glish-whql.exe
- Download the modified nv_disp.inf file from here: http://home.comcast.net/~twocables/nv_disp.inf
- Download Driver Sweeper 2.9.0: http://www.phyxion.net/Driver-Sweepe...Installer.html
- Run the Quadro driver installer in order to extract its contents to the default location of
- Then the installer opens up and tells you that you have no supporting hardware. However, this is because the GTX 260 isn't listed in its included nv_disp.inf file. So, we're going to change that.
- Close the installer
- Copy the modified nv_disp.inf file to this folder to replace the original (or just download it right to this folder once it gets created):
- Install Driver Sweeper (reboot if it asks you to, otherwise a reboot is not needed before continuing)
- Uninstall the current display driver using the Programs and Features control panel
- Close everything and reboot into Safe Mode
- To enter Safe Mode, hold down F8, overlapping the moment where the motherboard is done with the POST and begins trying to load Windows
- Once you're in Safe Mode, open Driver Sweeper (open the Start Menu and type driver sweeper)
- Select "NVIDIA - Display"
- Click "Clean"
- Reboot (it will ask if you want to reboot)
- When you're back into Windows, run setup.exe from this folder:
- Click "AGREE AND CONTINUE"
- Choose the "Custom (Advanced)" installation type
- Click Next
- Deselect both "HD Audio Driver" and "3D Vision Driver" unless you absolutely know you'll need one or both of these (the HD Audio Driver is for audio through HDMI)
- Enable "Perform clean install" which is located beneath these options
- Click Next and finish the installation.
When you're finished, check the Programs and Features control panel to see if PhysX is still installed. It should still be there, but if it isn't, then download it from here: http://us.download.nvidia.com/Window...emSoftware.exe
