System Requirements
LPVR in its current version runs exclusively on Windows, from Windows 10 upwards.
SteamVR must be installed and operational. Make sure your SteamVR version is newer than 1.9.16. Please also make sure that you are not using SteamVR 1.16 which has a known bug that will lead to subpar performance. Please refer to this page on how to gain control over SteamVR versions.
Currently LPVR natively works with the Advanced Realtime Tracking (ART) optical tracking system.
This driver plugs into SteamVR. You will not need any modifications to your Unity, Unreal or other SteamVR application code. Use the standard SteamVR interfaces to support headset tracking.
