Rotation and Scaling will not have an impact since BMAX calculates each vertex position everytime you draw an image. Having said that, scaling an image so it fills a large proportion of the screen will impact performance but only because of fill-rate issues.
Blendmodes are handled by the 3d Hardware not software, disabling these could give an FPS boost on older 3D GFX hardware.
So this all points to a GFX Hardware problem and not an issue with BMAX. I suppose you could re-write the drawing function to ignore scaling and rotation, not sure if you'd get much of a boost though.
