I think you may underestimate the processing power of modern machines :)

Transforming objects into world space and polygons to screen space already
requires more complex calculations than the above per vertex. Shaders,
shadows and lighting require more complex calculations per _pixel_. Granted,
most of that occurs in 3d accelerator cards nowdays, but you still have to
deal with things like collision detection, interpolation, networking, and
physics. I'm sure your CPU won't mind having to do one more add, mult, and
div per animated object!
