In Version 1.59 of C4 is some new optimized multi-threaded skinning of animated meshes. Here is a showcase thread about a scene rendering 100 animated models with a lot of graphical features enabled.
Impressive power:

Voxel terrain is something that id Software will have in the next id-Tech engine. It is already reality in the C4 engine.
