[OT] To the programmers (OpenGL)

Maybe I'm wrong, but I think you as going to implement an OpenGL renderer for Exult, am I right? Said this:
in OpenGL, one of the most performance degrading tasks, is texture swapping. Assuming that each shape is actually a texture, the variety of Ultima 7 would require a huge amount of texture swappings per frame. Are you experiencing problems with this?
Also: of course all shapes have to be masked. This is typically accomplished with Alpha Test. Any serious slowdowns due to Alpha testing? Everyone says it's almost non-costings in terms of rendering, but on the other hand, I am experiencing serious performance degradation because of that.
