Multiple VR headsets.

[Me]

I'm about to drop $6k on a new VR setup (using valve indexes). I would LOVE to do two headsets on one thread ripper computer with two gpu's. Everything I have researched has indicated that steam will not allow that in one OS, but it is barely possible using virtual machine magic.

Now I'm familiar with Linux KVM, Hyper-V and VMware, I know each can do this. But I'm left profoundly wondering why I should have to. Why cant valve just let us run two instances of a vr headset in the same OS like god intended? I don't even care if I have to buy two copies of every game or use multiple steam accounts. There seems to be more than a few people interested in doing this.

Even if you discount limitations imposed by Valve, many game devs have their games check for existing instances upon launch, and there's little Valve can do about their individual decisions.

Would like to know how VMs fare in these scenarios though. Doubt you can use the same account (even Family Sharing doesn't allow multiple accounts to use the same library concurrently), but the rest should work assuming you distribute enough computing power.

Building 2 3600 rigs would likely be cheaper with less of a headache.

Because PC is designed/intended for single user not multiple users at the same time.

For that you need specialized hardware/software in order to have seperate instances of OS/game at the same time.

This is why LTT did this build a year ago to have 3 VR users on 1 PC

I have found three instances of people doing it with good results. LTT did it as a sponsored bit with lintel using Linux kvm but he was retarded about the use of lighthouses, another guy did the same ting a bit earlier. And a third guy used windows server hyper-v. Most of my experience has been with VMware ESXI and I'm fairly comfortable with its PCI express pass through. None of them have a very elegant solution for USB, often using an add-on card for each clients USB needs.

Yes, but then I cant justify the 3960X purchase.

But how much of my life want to be without ray tracing and a threadripper?

If this is only for gaming you can get a build for much cheaper.

ThreadRipper would be pointless to use when the newer 3970X beats all those 1st and 2nd Gen TR stuff. Unless you wait for TR 3rd Gen which is coming sometime around Q1/Q2 of 2020
