Added data for the game, let's guess!

If they're adding 4k support in 3.2, there should also be HQ textures.. Not that much point doing 4k support with the current textures really.

Although.. That wouldn't really explain the increase for consoles, since those aren't likely to get higher resolution textures.

I'm pretty sure the "4k support" is simply for UI compatiblity. Currently, 3840 x 2160 makes text, icons, etc miniscule and difficult to read.

Otherwise, FFXIV already plays well in 4k.
