Your Eyes might not be adjusted
Your eyes may take some time to adjust to viewing stereoscopic 3D effects. If you are new to gaming, make sure you start your depth amount at the default of 15%. As your eyes adjust, you can increase the depth amount.
Depth Needs Adjusting
Adjust depth amount using the slider on the NVIDIA Control Panel Setup screen. If you are in a game, use the thumb wheel on the back of the IR emitter or the shortcut keys Ctrl+F3 to decrease depth and Ctrl+F4 to increase depth.
The game is not Configured Properly
If your game is not functioning in stereoscopic 3D, look at the list of compatible games shown on the NVIDIA Control Panel View Compatibility with Games screen. Verify that your game has been tested by NVIDIA and has been ranked as Excellent, Good, or Fair. Check out the Issues and recommended settings listed at the bottom of the screen. Make any adjustments recommended by NVIDIA to make your gaming experience better.
If it has a Not Recommended rating, it means that the game does not show in stereoscopic 3D or it shows very poorly. Make sure you are running your game in resolutions that support GeForce 3D Vision. In order to support GeForce 3D Vision, your game must be configured to run at the correct settings for your display. If you have:
120 Hz LCD: Select an in-game resolution native to your 3D Vision supported monitor. This is usually 1680x1050 or 1920x1080.
DLP HDTV: Select a resolution of 1920x1080, 1768x992 or 1280x1024 and set the refresh to 60 Hz.
DepthQ® HD 3D Projector: Select a resolution of 1280x720
