IMHO this composite could and should be done in hardware when possible a) to avoid dependency on closed source applications b) to avoid extra "render to L/R textures (not fb)" and "render L/R to Front/Back" passes (I guess this needs a fragment shader ?) c) to be faster The only settings you can change in the iz3D DirectX driver, I'm aware of, are 1) the stereo base 2) the virtual screen plane (separating objects into "in front of" or "behind the screen plane") and both only affect the creation of the Left/Right images.
