Supposedly AH doesn't use anisotropic filtering.
Other than that... one thing I might suggest "just for the eye candy" -- if you have the power for it.
Transparency anti-aliasing will make some things look better. Like the tower windows and railings, for one. These are textures that have transparent parts. FSAA only works on the edges, not where transparent textures kick in, so it doesn't help with them.
It eats up more power, but when it's on it'll look nicer.
Other than that I don't see anything blatantly out of order. Was there something wrong, specifically?
