SteamVR Controls
Controller mapping for every major SteamVR headset.
One More Delve on SteamVR supports all major PCVR headsets including Valve Index, HTC Vive families, Windows Mixed Reality headsets (HP Reverb G2 noted specifically), and Pimax. Controls map to standard SteamVR bindings but may vary by controller type.

Platform-Specific Notes
Valve Index Controllers
Index controllers support full finger tracking. One More Delve does not currently use finger tracking for in-game actions — all interactions use grip triggers.
HP Reverb G2 Controllers
ATVR has noted specifically that HP Reverb G2 controllers are supported for One More Delve. Note: Windows Mixed Reality platform only supports the HP Reverb G2 controllers, not other WMR controllers.
Two-Handed Weapons
Hold grip triggers on both controllers simultaneously for two-handed weapons. The weapon locks to both hands and full swing physics activate.
DirectX 11 Option
The May 2026 sprinting update added an optional DirectX 11 launch option for users experiencing issues with the default DirectX 12 renderer. Right-click the game in Steam, go to Properties, and add -dx11 to the launch options if needed.
