Anyone using the Razer OSVR and AC?

    Since AC is supporting OpenVR, the OSVR should be also (theoretically) supported. By accident I could buy a Razer OSVR on the cheap. If there is any AC racer out there using an OSVR headset with AC, please share your experiences. Thanks! :)

    UPDATE: short review here

    The model you are considering, is it the HDK2?

    Very detailed review, lot of information and in fact a top notch VR headset. IMHO "better" than OR and Vive, because it's thinking out of the box - that said open source. Now much more consumer friendly (coming along with an one click windows installer) and compatible with many VR titles on Steam, including AC since OpenVR. I will buy one and for sure when I got my first impressions I'm going to share them here.

    Great news @3dchips looking forward for your comments and impressions.
    Thank you for the review also, sounds good and might be a good alternative to the major if it works as described here.

    Sound advice Eduardo.

    Just as VR-virgins don't get VR's potential until they try it for themselves; they also don't understand the effects of poor head-tracking.

    I hope OSVR use a mounting-solution similar to the PSVR or Lenovo HMD's with the final version. I really don't miss the straps used on the DK2 at all and those used on the HDK2 look very similar. I do like the adjustable lenses though, and hope those become more standard.

    Increased competition should promote better features, design and function over time and we'll have much improved VR hardware in the future. Maintaining a high standard for good VR performance has to be a high priority and that is where the low-cost VR options could be detrimental to overall VR progress. User safety and access to well-developed VR-titles should be serious considerations for any VR purchase. As responsible VR enthusiasts, I think it's in our own best interest as well as VR, to be vigilant about pointing that out.

    AFAIK Oculus Rift users have been complaining about a patch a few weeks ago (or a few days more, dunno) that the tracking on motion sims was broken. NTL I like to go the open source route so I ordered a Razor OSVR today.

    Yes, Oculus are still trying to sort out some USB-issues and it's unclear if / how they are tied to CPU-core performance since OH-v1.3's release but, it's clearly affecting performance in multiple titles. Some recent reports seem to point to Steam related issues where the tracking-hitches go away when disabling some Steam services but, that's not been confirmed AFAIK.

    ok, here we go. I'm not a native English speaker, so expect may be any mistakes :)

    The Razer HDK 2.0 is an alternative headset on the market in comparison with VIVE HTC and Oculus Rift.

    Disclaimer: no guarantee about my thoughts, experiences, impressions - it's my opinion and was gained by doing this and that.

    Please beware: Razer HDK 2.0 is not a plug & play headset (it could be, but still it isn't), it's in development and there are still a few bugs especially the tracking =>

    There is a judder creeping in after 10 - 30 mins when turning the head (POV is jumping side-to-side and back-to-front a few inches). The judder seems to be a result of the velocity data coming from the new unified tracking system (not confirmed). As reported the tracking system is sending incorrect data (or SteamVR's tracking prediction stuff is "**"*. BTW SteamVR-OSVR supports (now) distortion correction).
    At the moment there is still no solution in sight, though the devs are looking for a solution. Restarting the OSVR server helps (it's only a workaround, restarting the server via batch script eliminates the issue for the next 15 minutes).
    Aside form this, all is working fine. NTL until this issue is not going to be solved, I cannot recommend the Razer HDK 2.0 for anyone except for devs.

    A few Cons and Pros
    • I'm wearer of glasses, in my case no glasses needed (diopters cover +4.5 to -2 adjustments). Dual lens system design that allows to change the focus of individual lens on the fly. De facto I can wear contact lens, or no lens but no glasses: there is no space for the latter (glasses would scratch the lens of the headset).
    • Upgradable (also for future use), both software and hardware. I had to update the LEDs with a new firmware (by using a ST-Link/V2 programming micro controller). For that procedure I had to open the case (no witchcraft needed), though not everybody likes to open a headset, but if one part is broken you can replace any parts, more information at https://osvrstore.com/.
    • Almost a hardly remarkable screen door effect, that said reduced screendoor effect.
    • Display features 2160 x 1200 441ppi dual-display technology (1080 X 1200 per eye) and frame rate of 90 hz. Screen is bright and "crisp", there is a noticeable smearing in dark scenes when turning the head, the dual-display is pixelated at far distance, it's the state of the technology. Despite of this, the visuals are good, text is readable (for example Elite: Dangerous).
    • The field of view is 110-degrees. I cannot measure it, but it is sufficient as expected.
    • IR (infrared) camera (100hz) for positional head tracking, since version 0.6.1924-g5affce6 tracking is significantly improved and very smooth (aside from the bugs...). As already mentioned, I had to update the firmware and the drivers, furthermore finding the ideal position of the tracker. There is a yaw drift to the left, after one round Nordschleife you have to recenter your view. Still not solved by the devs.
    • IR works daytime or night
    • Pretty comfortable to wear, soft foam padding, acceptable weight. The eyes have to be centered, if not the "picture" is immediately getting unsharp.
    • HDK Windows Installer, that means one click installation.

    Playing AC: it's works as expected. Mirrors still 2D. Fast Approximate AA settings (effects) does not work (black screen).

    This post will be updated as soon I get any updates or any bugs will be solved. Any questions are welcome, you will get all your questions about Razer HDK 2.0 answered as long as I can help ;)

    Most obvious question about resolution: have you compared it to a vive or oculus?
