Windows 7 64bit Graphics Driver

1. The first screen shot shows Windows Server 2008 R2. Is that correct? It should say Windows 7 even though the version is 6.1.7601. Can you run msinfo32 from Start -> Run and post a screen shot similar to the following?

2. What year/model is your Mac?

Hmm, in advance difficult to say...

I have a mac pro 5.1 equiped with a gtx 980 ti. I too had seen this video card had been poorly supported by the standard bootcamp video driver. So i decided to install the nvidia windows driver for this card.

After i overcome my fearful tremble, i did it. Works perfect. Now the gtx 980 ti is perfectly supported for programs that are hungry for grafics performance. Star wars Battlefront has run perfectly under windows 7 inside te bootcamp environment.

And i am pretty sure, the grafics driver that is made for windows will install and work perfect with your iris.

But make a backup of your important data first, to be in the safe side, ahem, good side of the force ;-)

1. You have an iMac 14,1 which is a 21.5 in Late 2013 iMac based on Identify the model of your iMac - Apple Support .

2. From iMac (21.5-inch, Late 2013) - Technical Specifications, you can have one of these GPUs.

Graphics

• 2.7GHz
  Intel Iris Pro graphics
• 2.9GHz
  NVIDIA GeForce GT 750M graphics processor with 1GB of GDDR5 memory

3. You have to careful with drivers because your GPU is not the stock Intel GPU. Apple will usually modify it with their own branding. Can you expand the Components tab and look at Display? It will show the specific details of the GPU.

Your iMac should have one or the other GPU, but not both. If you are using the Intel GPU, you should not have an nVidia one. You can confirm that by looking at System Profiler -> Graphics/Displays on the OSX side.

You have a single Intel GPU. If the update fails, check Event Viewer. The Vendor ID/Product ID determines if the driver is for the specific device or not. Apple's modified versions may not allow for such an update.

There is a brute-force method to update drivers. Create a Windows System Restore point which will allow you roll back the driver in case of any issues. Right-click on the GPU in Windows Device Manager, uninstall and delete the GPU (but do not reboot). Run the driver executable if one is available. If an Inf file is available, click on Update driver -> Have Disk and point to this inf file and testify the driver will update.

Repeat this process after running the following two procedures.

Test.

The files shown in your second screen shot (4.JPG) can be either a single executable or a driver package with a .inf file.
