I played for an hour in #BeatSaber and #GunClubVR and I can say that the cover works great. Grip is perfect, I can release the controllers and they will not drop.

Here is a temporary solution for this foveated rendering problem - you can disable FFR completely with
#SideQuestVR
help.
But be aware, it will go back to default settings on headset reboot

#BeatSaber now looks great and smooth!
#GunClubVR looks good but have lags with FFR off😬
