UE4
There is no profile that works with all UE4 games, but there are a couple of profiles that work with different UE4 iterations, so the chance of getting basic Geometry 3D working with unknown UE4 games isn’t too bad.
Off the top of my head: Abzu, Hellblade: Senua’s Sacrifice, The Turing Test, Conarium.
Lenovo/WMR:
I have a Lenovo here for WMR testing. WMR headsets have their advantages and are definitely worth a look for someone who wants to buy a headset. But of course there are also things that Rift/Vive do better, so if you already own one switching between current headsets doesn’t make too much sense in the end if you ask me. Every single one has its pros and cons.
