DZVR supports OpenVR-compatible headsets. I have personally tested with Oculus Quest 2, HTC Vive, and Valve Index. Other OpenVR compatible headsets probably work just fine but may need to be tweaked a little.
Oculus Quest 2 - a bit too laggy, probably because it has to go through the normal OpenVR routines, then the Oculur Rift support, and finally gets processed on the headset itself. Controllers are way too small too. The screen is gorgeous, however.
HTV Vive - Just works. Very nice.
Valve Index - My personal favorite so far, although whoever made the controllers has some seriously limber wrists. Had to add some software angle offset to the controllers to not break mine (wrists!). Otherwise, just awesome!
