We've been battling performance with the realtime shaders for years. What we discovered is that the draw call runs as expected, but Softimage spends an awful amount of time figuring out if something needs to be drawn/updated. I think we measured it around 20% of the frame time - which is obscene when you compare it to a computer game which spends less than 2%. Then again, a game engine isn't an editing environment.
If these numbers are accurate, it might pay to just do a forced draw rather than spend time to figure it out.
