In the most recent update for its Oculus Rift VR device, Oculus removes software check that stopped users from playing Rift games on HTC Vive after trying hard to stop users from making use of a third-party software called Revive used to crack the HTC Vive’s DRM (digital rights management).
Even though the DRM removal wasn’t even announced or mentioned on the recent update, Oculus VR did confirm this to Ars Technica and others by stating it “will not use hardware checks as part of DRM on PC in the future.”
The author of Revive seemed surprised by his statement when he said: “I’ve only just tested this and I’m still in disbelief, but it looks like Oculus removed the headset check from the DRM in Oculus Runtime 1.5. As such I’ve reverted the DRM patch and removed all binaries from previous releases that contained the patch.”
