Turns out there is a new GUI, the positions are working the same, but the shading, texture and such are now all at the level of the new positions.

The person who told me about it seems to think they looked about the same, but I'm seeing the difference. The textures for all the positions are now looking the same to me, but there's the link. If you have a decent graphics card you can see for yourself. (A good indicator for me was that I could run the newer positions without trouble.)
What I would recommend is if you want a comparison do one of the earlier positions and one of the later (with one girl I compared normal ride with crazy, and she agreed) and you will see they are running at the same level with light and shading and such.
You can also notice the difference if you bring up pics from the gallery.
