I am flying CLOD with a Rift-S: https://forum.il2sturmovik.com/topic/68142-user-enabled-vr-my-current-vr-vorpx-settings-for-rift-s/
I use the IL2-COD-BLITZ-OBTv1.0 profile
this profile generally works, I had only to activate tracking with the ingame menu.
-Enable alternate hooking method is not required for my system.
Well I don`t know nothing about your HP Reverb G2 head set but:
For my Oculus I have to start a special demo mode in the Oculus software and define the programs which should be considered in this demo mode.
-Have you checked in VorpX that CLOD is not one of the excluded programs?
-Have you assigned the:
…\SteamLibrary\steamapps\common\IL-2 Sturmovik Cliffs of Dover Blitz\Launcher64.exe to your Local Profile?
(I am sure you have already done)
