Problem of this video is they reference 110 fov while 110 of other headset is horizontal, so this is incorrect comparision and make some people misunderstand.
But we ever asked about horizontal fov since the campaign still not end, but never got the real answer of horizontal fov. But some calculation tell that the more diagonal fov, the horizontal fov will be same.
Infact we can use this tool.
So, if someone at the meeting try this, we will get the real answer.
I ever test with samsung odyssey, it is around 105-106 fov.
