I've been playing through the DK2 since day one. Initially on a 780ti SLI build (till I realised SLI wasn't working) and now on a 980ti Sli build (except... well, see previous comment). I'm using the 0.5 SDK as I don't have anything else VR that I use any more. Motion sickness in the SRV is caused by low frame rates, and I believe this would be considerably better if they moved to the latest SDK. I
expect the Vive to offer the smoothest experience at launch because they've had time to work with the driver stack. That said - running on 1.5 super sampling on one 980ti and the experience is pretty rock-solid. The frame rate is pretty smooth, you just get some weird jumpiness. It's not specifically a low framerate, it's something else.
Anyway, I don't feel sick on planets any more
If they (FD) ever actually get hold of and implement OR 1.0 SDK, I'd expect performance to be very similar.
I considered ordering a Vive in addition to the Rift (justification: I work hard for my money!) but I'd be much happier if I could get it
without the full-blown room-scale tracker and the wands.
Considering I'd be buying it for a sitting down experience primarily and, frankly, I don't really want people walking around tethered to a £3k PC, falling over and doing all manner of damage - I can't see the point.
So: Oculus got to my wallet first. There's also the thing that the Vive is basically being used to try and revive a loss-making company in HTC (because nobody buys their phones any more, despite them being pretty good) - but I can't see them achieving the volumes they need to sustain a business.
Oculus, on the other hand, teamed up with Samsung. Now *that* was a smart move. They make pretty much the best hi-density small form factor panels (not necessarily talking about colour reproduction - as I believe the consensus is that Apple's panels for the iPhone are the still the best there), and can manufacture in the scales required to keep prices down. They also are now shipping GearVR free with S7s etc.
And then we have Valve. They've positioned themselved perfectly - they're the software provider. Capable sitting in the middle of all the future HMDs, offering their own ecosystem and potentially a unified platform for them all to support. They do the integration into SteamVR themselves - and I fully expect them to work with Oculus to bring OR 1.0 features into SteamVR.
It's just a shame that the two companies couldn't have continued their working relationship for longer to deliver a unified platform from day one - but of course they couldn't: FB is a content provider and so is Valve - you're not going to find them collaborating until each company has had time to carve out their respective market niches and then look to where they can 'safely' cooperate.
Blimey I've written a lot in here...
I'll shut up now.
