The latency problems are an entirely different beast when you're talking about head tracking. Carmack isn't talking about latency for button presses or stuff like that, he's talking about not having your view lag behind your head movement.
If the Rift is going to trick your brain into thinking you're standing and looking around in a game, you need to get under a certain threshold. The HMZ is way, way too slow.
haha what the hell are folks talking about in here.. Do ANY of you have the HMZ? and a PS3 game that allow you to use head tracking?
I have the thing and like I said, it is one to one with no sense of "lag behind your head movement".
i wonder if Carmack has used this setup as well (PS3, 3D, Move)...or is he just going based off specs and math. or just hooking it up with PC use. I know the guy is a 1000x smarter than me regarding this field. But its like he says something, then everyone here just repeats what he says without having experienced it to confirm. I'm reading "killz it" or "shits on it" or "omg the lag is so obvious, it is unplayable".. I'm like whaaaat?
i believe 1-D_FTW has it, and has his own complaints regarding the HMZ. But I don't know if he tried it with Datura, with head tracking.
