Better Display Driver under Windows 8 than Windows 7 for MacBook Pro Retina?

Question

Anyone happen to know if the display support for a MacBook Pro Retina is better under Windows 8 than it is under Windows 7?
Ideally, I would like to be able to run 2880x1800 at True Color as well as have the HDMI out fuction as a second display (maching the behaviour while booted under Max OS X 10.8).
Under Windows 7, the highest resolution that supports True Color is 1600x1200.  This would be okay if that setting did not distort the picture (everything is slightly squeezed).  At 2880x1800, the highest color depth is High Color (16-bit) which is, well, not something one can actually use if doing graphics work.  On my 27" iMac, 2680x1600 supports True Color as expected.
Also under Windows 7, the display connected via HDMI is not recognized.
I've contected both Apple care support and Microsoft support about this, but Apple referred me to Microsoft and Microsoft referrred me back to Apple.
Thanks,
Warren
P.S. Personally, I think it's rediculous to even attempt to do graphics work under Windows, but tell that to the Windwows based corporate world that I freelance in.

Answer 1

Yes, there is a better display driver for the MacBook Pro Retina while running Windows 7 Pro.
And, the answer is so obvious, that I feel a little silly having started this thread in the first place!
The Windows 7 Professional NVIDIA drivers for the NVIDIA GeForce GT 650M card need to be installed manually by downloading them from NVIDIA directly.
If you need to do this on your MBPr Boot Camp volume, use this link:
http://www.nvidia.com/Download/index.aspx?lang=en-us
Then, set the pop-up menus based on your MBPr. [Mine were as follows: GeForce; GeForce 600M Series (Notbooks); GeForce GT 650M; Windows 7 64-bit: English (US)]
What tipped me off to this is that the CUDA drivers need to be downloaded manually on the Mac OS X side to take full advantage of raytracing in Adobe After Effects CS6 and CC.  As soon as I started to run that installer it dawned on me, "Hey, you probably need to install the drivers on the Boot Camp side as well."  And sure enough after doing so, I am able select all of the expected resolutions as well as run 2880 x 1800 at Millions of Colors (32-bit).
I guess I'm showing my nearly three decades worth of being a Mac user where I'm accustomed to having about everything needed included with the OS.
