I also fully explored 3D last time around (the ASUS VR-100 V3800 TNT2 days), and recalled that it worked exceptionally well, but ONLY if you had the right setup. The key back then was a large (very expensive) CRT screen capable of 150Hz @ XGA resolutions with fast (low persistence) phosphor. With the right setup, I remember being blown away playing Motorhead for hours on end.
What is now very exciting about LCD shutter 3D is High Definition and modern digital displays. Low resolution SDTV / and slow CRT phosphors is what made LCD shutter 3D glasses a bad experience for most last time around.
Firstly, you need enough resolution to be able to create accurately offset left and right eye full detail images, and you need displays that are fast enough (as in persistence of image) to be able to show a clean left / right image to each eye at least 60 times per second (without image lag still ghosting the image meant only for the other eye). Once this is achieved you have a sharp, clear, visually accurate and non-headache inducing 3D experience.
This time around, full 1080p HD gives us the resolution we need to do this, and digital displays are getting faster - the only question I have is can an LCD display really be fast enough at 120Hz to truly avoid the left / right image ghosting which contributes to the headache issue? Or, do we still need to await a faster full HD display technology to make sharp, clear non-headache inducing 3D finally a reality for all?
