Hello, I just tested The Kremer Collection VR Museum and I can edit the game with QGO ;-) I created an HD profile for you ;-)
I already made HD profile for Deadalus few months ago
Concerning Lands End, yes it is a GeaVr app and QGO don't see it as a VR game. But I will update QGO to take into account the Gear VR games in my next update :)
