Most consumer-level hardware doesn't support the esoteric functions in the pixel path, but there's no hardware reason for the most common case (data format matches the window pixel format; no scale/bias, convolutions, scaling, etc.) to be slow. It's trickier than you might think to get the data formats to match the window exactly, and many driver writers for consumer-level cards *are* reluctant to optimize a function that they believe will never be used by their largest market (games). But my experience in the workstation world is that if the pixel path is optimized for the straightforward cases, people use it heavily.
