Linky for people with an Oculus Rift and a Razr Hydra:http://sixense.com/sixensetuscanydemo
Having "hands" in VR is absolutely fantastic.
Some thoughts after my playing around last night:
* the "screen-door" effect (due to having the pixels so close to your face) is certainly noticeable. Doesn't detract from the immersion, but does reduce image quality significantly. You kind of stop noticing after a while, but it is always there. Hopefully will be less of an issue with higher resolution retail versions.
* looking far off into the distance does suffer from blurry mess syndrome. In real life, your eyes magnify far away objects and I found myself repeatedly trying to do the same... obviously doesn't work. Again, perhaps an increase in rez might go some ways towards rectifying the problem.
* Most (all?) OR-enabled software had v-sync disabled (to minimize head-tracking latency). Screen tearing can be ugly when you see it, but wasn't particularly common (thanks to the game only having to output in 1280x800). Will try turning it on next time and see how much it affects things.
* Setting interpupillary distance seems to be pretty important. When I first jumped into TF2, I didn't bother running the vr_calibration console command and when I took the goggles off after a couple of minutes, my eyes had difficulty focussing for 30 seconds or so. Strangely, I didn't seem to have any issue with the sixense Tuscany demo, which I played for a lot longer (and has no such calibration... unless I missed it). Maybe my IPD is close to the default for the latter software.
* Managed to play about 15-20 minutes before motion sickness started rearing its head (and gradually worsening). Having read previous advice that it is not something you can push past, I stopped for the night. I'm told that it is something you get used to over time. See how I go tonight.
* Properly designed UI is key to the experience - TF2, while fantastic, really needs to work on a more readable UI in-game. Text is just too blurry to read. The tuscany hydra demo, on the other hand has absolutely nailed it.
The experience really is something to behold... once they get the resolution up and games are specifically designed for the platform (ie. minimal/clean user interface, separate head/body facing, stereo shadows), I can't see myself playing games any other way.
Up next: Dear Esther, Skyrim.
Really want to play the Hydra-enabled Portal 2 with OR, but it's an either/or dilemma (playing with Hydra disables the mouse, which is what Vireo Perception uses to enable OR head tracking). Maybe Valve will pull a rabbit out of a hat someday and fix it for us.
