I made this video to expose the expected 3D stereogram feature in rFactor 2. I define left and right eyes as camera (70 mm separation). I record both replays, I synchronize resulting videos in Adobe Premiere and Voilà !
To observe the 3D effect, look at the screen at about the same distance as the video separation on your screen (screen resolution dependancy) and focus your eyes far away (... been lunatic)
Note: Some times, someone is not able to observe that effect since it depend on eye dominancy. But if you got it, ... wow!
