I am not sure if this helps, but there are two articles on Dr Dobbs translating runtime polymorphism, to compile time construction. The downside is that it does not work in every sitaution (probably you must already know the class structure at compile time) and I have not tested it myself. If a virtual call is a bottleneck, than you have a really performance intensive application.
