Hey guys, I'm an educational software developer and I want to know how many Oculus Googles can be connected and used at the ssame time to a single powerfull PC? I want to build a laboratory and I want to know if can use a server with terminals and connect multiples Oculus headset at the same time with differents desktops(users)? I will buy a couple hundreds if it works to a single PC.

    Depends on how powerful you are talking here...

    The Oculus runtime only supports a single headset on a PC.

    What if you have a double headset, won't it be able to support it?

    I had a similar question, as when I watch a film on SkyboxVR I would be good if I can watch a film with my partner in our own private cinema!

    Thought about buying a USB & HDMI Y-splitter and connecting two headsets to the feed.

    But IF that would work I assume only one headset would control the viewpoint?

    That won’t work, each headset needs its own PC. You can watch movies together with other users in apps like Big Screen Beta.

    Don't think it's possible but. mind you, someone hooked up a Vive and a Rift to a single computer.

    Wow, I'd never have thought of doing that. Could this be the beginning of a beautiful relationship? (that's a rhetorical btw in case anyone is thinking of a bait post).


    Very clever though.

    You can also build a PC that runs two GPU's on one CPU with two different windows instances using Virtualisation



    Not sure if the Rift would support that! In theory, it should.

    that may be getting towards the realms of... better off buying 2 PCs territory... but I love the tech behind these ideas

    On the virtualisation side, it depends on how the display is handled. The rift needs special support inside of the nvidia/amd drivers (for direct mode display connection), so those would need to support virtualisation (so it would depend on where the gfx drivers were sitting, above or below the virtualisation layer). Who knows.

    One thing we know, the rift is extremely fussy about usb and hdmi ports and some people have enough trouble getting it to work on a typical PC. Making it jump through extra hoops is going to reduce it's chance of working.

    LZ, you have the job (and the resources) to undertake this mission, good luck


    (I suggest starting by lowering yourself from a cable suspended from the centre of the ceiling)

    It won't work, the GPU requirments for 1 HMD are high enough, and it was only designed for 1 HMD per PC.  But you could probably buy a couple of GearVRs and watch films with your partner using those instead of the PC.

    Interestingly, you can connect 2 PCs together to use just 1 mouse & monitor and so surely you can then connect each a HMD but use just the one installation of software?
    It really should not be a case of buying double your games/apps for each computer!

    TL:DR = Possible using virtualisation, but would just be SO much easier/cheaper getting minimum spec VR PC's

    You could use virtualisation. Set up correctly it COULD be possible, but i'm not sure how that would work with GPU's etc. I've heard doing this kind of thing is a lot easier on a Linix machine as well, as windows has some outdated practices on resource management. 

    The other problem you will run into, is when getting to that level of performance, the price jumps exponentially. 

    In the end, if would be MUCH cheaper, running multiple headsets on multiple minimum spec PC's, using a pre-built image to ensure all computers are the same, lock everything down with group policy so that students cannot access anything they shouldn't, and then finally using something like Impero to monitor. 

    Edit: Regardless of what you would do, you would need duplicate software/games/apps for each HMD

    No, I don't believe virtual machines will work as they don't typically have direct access to the GPU (at least not without some complex configurations) so VR won't function. And, even assuming it would work (I don't think it would), VR is usually very intensive graphically and it's already a struggle to hit 90fps with one app running dedicated on a PC, so running two or more 3D apps (plus the VM overhead) on one machine does not seem feasible.

    Might be able to use it with a VM machine, but simultaneously on one PC might not play well with the resources, good luck be curious to see if you get it working

    I wonder if Ibik Astor would work with multiple GPUs in one PC with multi headsets.  Might need an add in USB 3.0 card too.

    In time, the tech will evolve. I built a KA machine last Mar but waited for the latest Rift update to buy the tech. I'd love to take my sweetheart into the ole west to resend some zombies to their maker but we just aren't there yet.....it will come.

    I built my 1st machine for my home in '81, 8086 or 8088? chip(was more than a moment ago)......I'm loving the evolution over the past 40 years......but it hasn't been the "accepters" who have driven it, it has been the innovators, the guys who "rig things up" to make them work, who solve the next puzzle.....to them, thank you!

    I believe I should be able to run two rifts off one machine. My desktop has an i9 processor, 16gb RAM, NVIDIA 2080 w/16gb RAM. I have 8 3.0 USB ports and the 2080 has 4 DCI(?) and 1 HDMI output.

    Maybe the title of this thread should be changed to;

    How many Oculus forum one post wonders does it take to change a light bulb?

    Just kidding, my bad, lol!

    To quote myself from the top of this thread: "The Oculus runtime only supports a single headset on a PC."
    That is still true. It doesn't matter what your hardware is, the Oculus runtime only supports a single headset on a PC.
