FOV in game?
Actually I just received my rift, and I can see there is three sets of lenses. Each set give us a different FOV. (Lets forget the stereoscopy here, and imagine we have just one eye/image) But...
WEll, if i Use A lens (big FOV, low res), or C lens (low Fov, high RES), the difference is more than obvious.
Even if I calibrate both of them.
With the same source, same image displayed on screen.
the image is not "stretched" the same, beetween A lens, or C lens.
The top left pixel in one case will be at 120° with A lens, while the same left pixel will be at 90° with C lens for example.
I would be agree with your analysis, if the Fov changed beetween lens, but not the resolution.
but the fact the resolution change too, means that the position of pixel change on the FOV.
So if you can't be sure, in game, wich pixel will be restitued at wich degree of the FOV in the final rendering, its problematic for perfect realism.
