Yes, among other things. They use 2 renders per screen, so you should be expecting about 16ms more latency than oculus. Also they have double the vertical pixels compared to oculus, so you might expect more latency compared to the oculus screen from computations too. Latency comes down to several factors, rendering latency, screen latency and everything in between. pixel to pixel latency is very much dependant on the screen type. Oculus has said theyre looking into OLED screens that have minimal latency (few ms) compared to lcd screens that have about 16ms or so.
