Capturing Screenshots & Movies in Stereoscopic 3D

When you are playing a game with NVIDIA 3D Vision, take an in-game screenshot in 3D by pressing ALT-F1. These 3D screenshots will be copied into the folder “C:\Users\[USERNAME]\Documents\NVStereoscopic3D.IMG” with the file extension JPS. A JPS file is a stereoscopic 3D JPEG file and can be viewer with the NVIDIA 3D Vision Photo Viewer.
If you want to increase the quality of the .jps images, you need to run "Regedit" and navigate to the following place in the registry depending on your OS and then just change the value of SnapShotQuality to the desired level of quality.

For 32-bit Windows:

For 64-bit Windows:
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\NVIDIA Corporation\Global\Stereo3D]

The value is represented in percents in decimal numbers, so when you change it you need to enter decimal and not HEX values (HEX is still Ok if you input the right value, because 50 in HEX is equal to the number 80 in decimal!). So the default value you'll see is 50 in decimal meaning 50 percent quality which gives a smaller file, but a lot of visual artifacts due to the compression of the image, so you definitely need to increase that value. Have in mind that 99 is the maximum value you need to enter in order to get the highest quality level, if you input 100 or more you'll actually get 75 as a quality level instead, so be careful that you input 99 in decimal as maximum number to get the highest possible quality!

Also you can modify the default "Alt+F1" key combination, thats used to capture the 3D image, to something more confortable like "Alt+Z".
Some games may even crash if the default keys are pressed.
You need to run "Regedit" and navigate to the place in the registry depending on your OS (same as above), and then just change the value of SaveStereoImage to the desired combination, i.e., "Alt+Z" is O45a (hexadecimal) and "mouse middle button" (only) is OOO4.
