Based on comparative reviews (like the PC Gamer article linked above) and my own experience as a DK2 owner and trying the HTC Vive last year, I pre-ordered the CV1.
Price aside (although the Vive is almost certainly going to be the top-end system) there are a number of factors to buying the next generation of VR Head Mounted Displays (HMDs).
- | Oculus DK2 | Oculus CV1 | HTC Vive |
Display resolution | 1920x1080 @ 75fps | 2160x1200 @ 90fps | 2160x1200 @ 90fps |
Accessories | none | XBox controller - motion controllers to purchase later (additional cost) | possibly - may affect price if included |
Weight | heavy on the neck | very light | Dev kit was same as DK2 and new version looks the same and includes camera. PC Gamer reviewer said heavy. |
Motion tracking | Wired USB IR webcam | Wired USB 6 inch desk boom | Two wall-mounted (or tripod-mounted )IR sensors approx. 6cm cubed. Wireless but require power (wired) or batteries. |
Heat | Hot to wear for long periods due to heavy plastic not breathing and large straps | Lighter, breathable materials with smaller straps | If straps/faceplate remain, same issue as DK2 |
Space required | 5 sq ft - short range motion tracking | 5 sq ft - full room tracking | 10 sq ft (more if using tripods) - full room tracking |
Sight adjustment | Two lenses (short/normal sight) - software IPD setting | Hardware IPD adjustment (focus slider) | Hardware IPD adjustment () |
The Oculus offering is most likely the cheapest and is the most refined, being very light and comfortable. It also doesn't require much space to use and will be portable. But the motion controllers are going be delayed and cost extra (if you want them). It also doesn't include a built-in camera, so peeking under the visor to see the keyboard will be required.
The Vive's front-facing camera is a major advantage, offering "sight" on demand without removing the visor for people who are not touch-typists and offers a world of augmented reality possibilities, but the motion tracking system requires a lot more room and the sensors are not exactly "discrete". Also, unless they make a third edition of the Vive before release that's smaller and lighter with smaller straps, then it will have the same issues of heat, weight and discomfort that the DK2 had.
Both units are the same resolution and should be supported by most VR applications, so choosing one device won't preclude you from a range of games and apps.
In the end, I think it will be down to your budget, how much room you have and personal preference. I don't have a lot of room, so for me, it was the CV1.
