Is there a list of games available on GOG that support VR? Couldn't find one doing a search.

I don't know if there's a full list available, but here's at least one, that I know of:

Edit: oh, and this one:

Edit: this user has made a (short) list of GOG games, which he played on his Vive (though most are already mentioned here): https://www.gog.com/forum/general/is_gog_going_to_be_carrying_vr_games_at_any_point/post8

But in general - shouldn't all VR able GOG-games work if they're supported by one or more VR headsets?
