Many reviews have I read, you know, reviews for the Oculus Rift DK2 where enthusiasts alike are talking about the Screendoor Effect". In my opinion, I believe a few of these reviews are coming from those who have never tried the Oculus Rift DK1. Truthfully, I been actively using the Oculus Rift DK1 for about 1 year now. The difference is truly night and day! The Oculus Rift DK1 screen door was unbearable at times, but, you just had to push through it because, it was just that immersive.
The Oculus Rift DK2 is absolutely, no doubt about it, better. Picture this, within mere seconds your eyes adjust, the crispness and the scene comes to life exceeding expectations. As enthusiasts, gamers, critics and reviewers have pointed out: the Tuscany demo at this resolution immediately reveals its age. This demo is no longer sufficient for this screen; Elite Dangerous or Technolust will make jaws drop (for real).
For those that see or have seen very small pixels (compared to the Oculus Rift DK1) perhaps try Mayaman's Hack with the privacy screen overlaid on the OLED panel, I would be interested to hear how that turns out.
