 ## VR
 
 The **VR** options row (OFF / ON, off by default) drives a PCVR headset
-through OpenXR on Windows — SteamVR, Oculus or WMR. On the orbit rungs
-the world is a head-tracked tabletop diorama at the rung's own angle; on
-**1ST** you stand inside it at life size; a battle snaps you (through a
-fade) into the game's own over-the-shoulder shot. Menus float on a
-panel wearing the Game Boy frame, and in first person they show up on
-the **Pokédex in your left hand** instead. Turning VR off is the VR
-row's job — no controller button does it.
