Couple things.
Both TerraPak and SeaVue need Vue6 Esprit or better to work.

If Crisp AA doesn't work better, then try ZERO AA for a specific material. It will render much faster, too. You can turn off AA on a material by material basis in the Material editor (top right).

Sometimes zero AA helps things, sometimes it doesn't. Generally if you texture looks too blurry, you can use it. Never use it on animations.
