I see. So in theory it would've been noticeable had, say, the PS4 Pro run NieR at higher resolutions?
From what I can tell from screenshots, the PS4 Pro version also seems to use the same 800x450 buffers for effects that the plain PS4 version uses. Despite rendering at 1080p. (It really is exactly the PC version at 1080p with MSAA off and low AF)
