Tessellation and Parallax Occlusion depend on the resolution of the texture being "bumpified".

The textures in FFXIV must fit in a PS3's 256 MB of VRAM.

This is the result.

Until the PS3 is finally kicked to the curb and the game can be developed for PCs and PS4 with large memory pools, this what we have to live with. The other improvements in DX11 such as lighting/shading and reflections are very nice though.
