That's because the terrain.png texture can be huge but each individual texture is only 256x256 max.

Which means that the textures you see in-game are never larger than 256x256 which isn't HD by a long shot.

Oh yeah I know they're not actually real HD. I just meant HD in a 'better looking' sort of way.
