Vengali, thanks for the support, however this is what I have been doing and still am receiving an error.
let me walk through EXACTLY what i am doing to see if you spot an error.
1. Download the driver from http://www.geforce.com/drivers/results/46279
2. It opens automatically and install fails.
3. navigate to computer>bootcampC:>NVIDIA>DisplayDriver>304.79>Win8_64>English>display.driver
4. Open up nv_disp
5. add a line directly under containing:
%NVIDIA_DEV.0FD5.00F2.106B% = Section029, PCI\VEN_10DE&DEV_0FD5&SUBSYS_00F2106B
too the four sections that fall under the title
a) [NVIDIA_SetB_Devices.NTamd64.6.0]
b) [NVIDIA_SetA_Devices.NTamd64.6.0]
c) [NVIDIA_SetA_Devices.NTamd64.6.1]
d)[NVIDIA_SetA_Devices.NTamd64.6.2]
6. crtl+f to find NVIDIA_DEV.0FC2 = "NVIDIA GeForce GT 630 ". press return to enter another line : NVIDIA_DEV.0FD5.00F2.106B = "NVIDIA GeForce GT 650M"
7. save.
8. navigate to computer>bootcampC:>NVIDIA>DisplayDriver>304.79>Win8_64>English and launch setup
when I launch it, no change, it immediately says error, hardware not found.
I have the macbookpro that is NOT retina display, but has the geforce gt 650m-the 2.6ghz model. $2199
thanks again
