I wrote some Managed Direct3D Mobile code, using fixed point arithmetic. It runs slow as a dog and its performance relative to the floating point version of the code shows little improvement.

This is on a Kaiser phone. I know that there are issues with graphics on that thing. I am only trying to use the software renderer, but the speed of my app is so slow that I wonder if it's in my implementation. It is a cube with textured faces, spinning as as fast as it can, and I can only achieve 7 seconds per frame (yes... seconds per frame. Obviously my goal is something in the FPS range!).

Would anyone with experience in writing D3DM code care to give me a hand by looking at my code? I'm at kramer (underscore inserted) ae (at) hotmail (dot) com.

Thanks,
Brian
