I had a good anaglyph 3d glasses, but they are not red–blue-green–purple (what is called the green–magenta). And then I discovered a nasty thing — in the 3d setup from NVIDIA, if you choose a combination of calibration images corresponding non red–blue glasses, the setting bar just sends me to the forest. After some research, I found that earlier it was possible to adjust 3d to any type of glasses. As I understand it, this setting just somehow turned off in the newer drivers. The version of fire wood I have 260.99
How to be now, maybe someone knows?
