Im wondering no one is posting about gw2. Im playing this for regulare already some months with vorpx and its running very well. No g 3d, but the z 3d looks very beautyful and its an absolutly good play in vr.
Its free and everbody who wants, can give it a try. No special settings needed, use only ingame the free camera and the action camera and max the fov.
Im already level 38 in vr :)
