Played about 2.5 hours worth, an hour straight at first with no real issues.
When I turned it on with the slider at full, about 20 seconds after the first 3D effects came on I felt a tension in my brain that does often preclude headaches. It spooked me, I turned the 3D off an it went away instantly.
Then I think I screwed around with the slider for a few minutes but ultimatley I just left the 3D on full and at some point forgot about the tension. I never ended up with a full blown headache.
