How to take in-game 3D Stereo screenshots in JPS format

June 20th, 2009 · 3 Comments · GeForce 3D Vision

While you are playing a game or using a 3D program compatible with GeForce 3D Vision you can take screenshots in JPS format that can be viewed later on in a 3D form instead of the normal “flat” 2D screenshots that can be saved on JPEG format. If you press the Print Screen button or use a program like FRAPS to take in-game screenshots when using GeForce 3D Vision you’ll notice that only normal (single frame) images are being saved. But if you press ALT + F1 instead while in the game you can save a JPS screenshot that actually contains 2 images – one for the left eye and one for the right, thus allowing you to see the image in 3D Stereo mode with a compatible viewer. The 3D screenshots are being saved in a folder called NVStereoscopic3D.IMG in your current user’s My Documents folder. The only drawback when taking 3D Stereo screenshots is that it takes some time, when you press the key combination to save a JPS file you may have to wait for a second until it is ready…


By default when you install the GeForce 3D Vision drivers you also get the Nvidia 3D Vision Photo Viewer that is needed in order for you to be able to open JPS files and view them in 3D Stereo mode. When you open an image in full screen it is shown in 3D mode, and when you exit the full screen mode it gets in a side by side view of the two frames (the ones for the left and for the right eye). You should have in mind that when viewing the 3D stereo images you cannot change their level of depth like you can in a normal 3D application… when making the screenshots they are being saved in the depth level you were using in the actual game or other 3D application.
