NVM. I just researched the topic: The VR mods are for the BFG version of Doom 3. But i don’t see the problem: Doom 3 BFG has better lighting and better gameplay anyway.
Given that neither VorpX nor HelixVision will run Doom 3, you really have only 2 choices. Play it native on Quest (you lose stencil shadows, the signature shadows of Doom 3), or play Doom 3 BFG w- VR mod (you still can play wireless).
Anyone correct me, please, if i’m spreading wrong info here.
