bootcamp graphic card driver

Try installing the latest beta driver > http://www.nvidia.com/object/win8-win7-winvista-64bit-310.90-whql-driver.html

In that case, the beta driver should have worked, because it's compatible with both desktop and notebook graphic cards. So strange

Not strange at all. NVIDIA is like AMD. They release matching driver versions for desktops and notebooks, but they are packaged as separate files/downloads. This is what you want for NVIDIA-based mobile GPUs:

Note the notebook designation in the URL.

I have the exact same problem. Where is the mobile version of it ?? Mine is a GT 640M...

FYI, I had a similar problem with installing Windows 8 64-bit on a new 2012 iMac 27" w/ a Nvidia GTX 675MX. Boot Camp 5.0.5033 hadn't even tried to install the Nvidia driver package (though it did linger on the ATI package install), and thus I was left with the crappy generic windows display driver.

Things I tried:

(1) Ran the Nvidia installer in the Boot Camp package. After the Installer window comes up, it failed with something like an "Installer Error" and an empty multi-column table.

(2) Went to Nvidia's site and ran the Java-based GPU auto-detect. It properly detected the GTX 675MX, but then it said there's "no compatible package available for download".

(3) Selected the correct hardware manually from Nvidia's driver list yielded a driver package for download (version 314.22, http://www.geforce.com/drivers/results/59645). However, running it brought up the Installer window (like the Boot Camp package did), executes a scan and then errors out with "No compatible hardware found".

Note that the installer package download for the selected GTX 675MX had the word "desktop" in the filename, not "notebook" like some other posts suggest it should.

(4) Searched for older driver packages at http://www.geforce.com/drivers/beta-legacy, I tried the next most-recent, non-beta driver package (version 314.07, http://www.geforce.com/drivers/results/57100). This driver package had the word "notebook" in the filename. The Installer window came up, executed a scan and then INSTALLED JUST FINE.

Results from a subsequent 3dmark run confirm that all the necessary drivers were installed properly.

Hope this helps somebody.

Yes, simply installed an older version of the driver made it work. The latest driver still not working but at least the device manager list my Geforce in the graphic card directory

thank you

This thread has been idle for awhile but since it solved my problem I thought I would contribute.

My Windows 7 Bootcamp install didn't go well because I had the support drivers loaded on an external USB HD, and the Windows DVD on a USB Super Drive. Turns out, Windows won't install with the HD connected to the USB port (took 5 hours before I found that tidbit on a forum). I disconnected the HD and Windows loaded fine, but I had to go back and manually run the exec file for the drivers. As a result, the NVidia drivers didn't install and I had the same problem described above.

I went to the NVidia Driver web site http://www.geforce.com/drivers and, using Manual Driver Search, went through each horizontal dropdown to select the GTX 660M and download the most recent non-beta driver (320.49 as of today). The install took about 10 minutes and it's beautiful. I went from a display that looked like I was viewing content through a 27-inch wide aquarium to a display so crisp and bright I need sunglasses.

Hope this helps someone.

Thanks for the up-to-date posting, Barometer. I only just today tried loading a new partition of Windows 7 on my late 2012 27" iMac - thought I'd stuffed up the installation when there was only a Generic graphics card.

Now my Boot Camp version sports the latest drivers for my GeForce GTX 680MX, and I couldn't be happier! 😁

I'll need to check out how well it renders games like L.A. Noire (which I've played under Parallels with some compromises). If native NVidia graphics are better, then I will likely use my Parallels partition for business, and Boot Camp for play.

Glad to hear you're fixed up. I'm guessing that running games native will be much better. I had Parallels with my old Mac and I think by default the memory was split 50/50 so I suffered poorer performance on both sides. After a few weeks I gave up on Parallels altogether and just started booting directly into Windows. Much smoother.

I was so skeptical that this wasn't going to work and it did. THANK YOU!!! I had just about given up and was ready to buy a POS windows machine. I can't believe this is not included stock in the Bootcamp install. Shame on you Apple.
