That's pretty much what games already use. The only difference is polygon count--doubling the polygons tends to halve the framerate.
That said, of the magic comes from a toolchain that lets artists work with curved surfaces (NURBS or similar) and that converts those surfaces to polygons at the last minute. We finally started getting hardware support for that sort of thing with DirectX 11 and OpenGL 4.
