The only way to optimize it is using Toms r2t.dll and instead of rendering to the backbuffer render to textures which you place then on the sprites.
That way you only need 2 renderworld calls per frame.
But in the end: even if optimized, your code needs some very good optimiations in other places ... 20 FPS on a X800? that means no FPS on normal graphic cards anymore.
