Re: Cannot Upgrade graphics card in Bootcamp for AMD Radeon HD 5750

I'm used to only updating the drivers via new bootcamp drivers from apple.com.

Q: Have you first checked to ensure you have done that step, prior to trying the AMD download if required?

• Go to [Apple] Boot Camp Support Software 5.1.5621, which applies to iMac (27-inch, Mid 2010), and follow the instructions there (exactly as per that article).

• Run DXDiag in Windows after performing the above step, check and note what Graphics driver you now have

• Only if necessary (if the APple Update did not include v13.12 or better), necessary, go to [AMD] Apple Boot Camp Software Graphics Drivers and grab the 169MB v13.25 drivers. Perform a clean install of those drivers if you can!

Hope this helps!
