Graphic problem in Windows with Boot Camp?

Question

I only just noticed this today when I was editing some pictures in Photoshop using Windows (Boot Camp). My version is Windows 8 64-bit and the Photoshop is CS 6 but I suspect the same thing would happen even if I were using Windows 7.
Whenever I view an image in Firefox, Chrome, Windows Picture Viewer or any other program besides Photoshop, the image is always displayed as it is and appears as crisp and sharp as it should. For example, if I load a picture that's 600x600 pixels outside of Photoshop, it would look exactly like it is - at 600x600.
But once I open it in Photoshop, and if it happens to be a very big picture (which it is for me, most of the time), the picture would look resized (i.e. smaller), but the Photoshop navigator would still say it's displayed at 100% magnification. So a 2000x2000 picture would basically look half its real size but still be at a zoom setting of 100% according to Photoshop.
That in itself isn't the problem, but trying to edit/crop the image is. If I were to select a part of the picture and resize it to, say, 100x100 pixels, the final image would be a bit blurry, even if I save it at "most high" quality. That obviously makes my image "un-usable" because the quality is so terrible. This doesn't happen at all on a computer without retina display but on mine it makes the task of editing images in Photoshop frustrating and pointless.
I really think it's an issue with retina display's native resolution not being supported in any version of Windows, so I'm hoping anyone who uses a Macbook Pro RD, Windows AND Photoshop could help me get around this problem.

Answer 1

Did you grab and install the graphic driver from Nvidia?
Apple or even Microsoft driver are not always the best.
Boot Camp 5.0 drivers to start just to enable the various chipsets and basic support.

I see a black screen or distortion when I install Windows 8 on a MacBook Pro (Retina, 13-inch, Late 2012). How do I fix this?
The Windows 8 installer does not contain the correct graphics driver for your computer. You'll need to attach the USB media that contains the Boot Camp drivers during installation to address this issue. See this article for more information.

Windows 8, Thunderbolt devices are being recognized when I connect in. How do I fix this?
Disable the Windows 8 Fast Boot feature to allow Thunderbolt devices to be recognized. See Boot Camp: Thunderbolt devices not recognized after Windows 8 upgrade for instructions.

Also with any GTX you may want to see if there is a CUDA driver as well.
Intel HD Graphics 4000
NVIDIA GeForce GT 650M with 1GB of GDDR5 memory and automatic graphics switching
Dual display and video mirroring: Simultaneously supports full native resolution on the built-in display and up to 2560 by 1600 pixels on up to two external displays, at millions of colors
Also, Intel 4000 graphic driver, switching between Intel HD and Nvidia has been a problem.
From my (now old) notes:
I had problems with windows 7 after the installation using boot camp. The GT 650M was not showing up as the graphics adapter. I fixed the problem by inserting my windows support software CD a second time. I did not let it use auto run.  I went into the Windows 7 directory and then into the Nvidia directory and ran setup.exe. This installed the Nvidia drivers for me. If this works correctly, you will have an Nvidia control panel available to you. I set the resolution to 2880x1800. I also set windows to 200% magnification.
I think what happens is that after you install windows, and then run the windows support CD, the main boot camp setup script seems to stop on the nvidia driver install--everything else installed correctly.
