When Vive Pro 2 launches in SteamVR with the SteamVR OpenXR runtime set, the actual runtime in use is Vive OpenXR, which breaks the hand tracking extension that bonelab's requires for index controllers to work properly. I don't see anyway to disable this. Using the OpenXR Toolkit downloaded from here: https://mbucchia.github.io/OpenXR-Toolkit/ actually corrects the runtime to SteamVR which allows the game to work properly, however this patch destroys framerate from the over head of the toolkit.
