Does the game-stereo driver stuff, like nVidia, really work?
Yes. It works on the 3D-API level (Direct3D, OpenGL). Since the API allows access to the 3D raw data the depth of objects can be determined. Since 3D-games are usually not written with Stereo3D in mind they often contain depth-errors, like wrong position of horizon, dust, fire, lightspots. Sometimes the differences in depth value between objects is so small no considerable effect is achieved. Therefore some programs look great, while others should be left in 2D mode.
