[SOLVED] On iMac with bootcamp, WIndows 8.1 can't find my GPU

[keithc]

On my iMac i have bootcamp running with windows 8.1 and when im in the Mac my GPU works fine but when im in Windows 8.1 it can't find my GPU? How can i fix this? I've went into device manger and under display adapter there is no GPU even though i have a GTX 775M on my iMac

I found a solution on a different forum, this guy said to download this driver http://www.nvidia.com/download/driverResults.aspx/70187/en-us and this worked perfectly, as soon as i started the install my computer found the GPU instantly
