I've interpreted presence as "how much can you fool the brain that you really are there".

The screen-door effect is still moderately high in DK2. I've heard the CV1 has much reduced the size of the pixels, so the effect is greatly reduced.

Also the refresh also needs to be jacked up further. I'd prefer 120hz or 240hz. That would assist in faster and more seamless head-tracking. I don't think HDMI can handle that much bandwidth though. I could be wrong.

Aside) The screendoor effect is the effect of magnifying pixels in a LCD screen so you can see the pixels along with the interstitial black space where the pixels arent. The black space creates black lines like a screen door. Your eyes will then flip on focusing on the image displayed and the screen door, losing the feeling of depth and presence.

The increased framerate only helps is the latency is low enough. If there is a very high framerate but the frames lag a few 10's of milliseconds behind the movement of the head of the user then that won't help one bit.

Of course. Ideally, head tracking would be locked to the latency no greater than the time between a frame.

240hz is only 4.16 ms, which is still within human perception of view. Ideally, I'd like 1khz refresh, but that's going to be a very long time away. I do remember an HN article recently discussing a 1khz 8bit screen with touch input running at 1khz as well. The comparison was fantastic and I believe also relevant.
