If you have a single core you would expect 100% utilisation, but multi cores and multi threading are far more complex - you have to run seperate threads for different parts of the game, but they may have dependencies on other threads, so may stop while waiting for input from something else on another core that has not finished. There will be a limit to how many threads can be split out before you actually slow things down - kind of like how SLI/crossfire does not scale to 300% with 3 cards - there is a law of diminishing returns. The devs are working to improve things, but dont expect a quad core to be automaticaly using twice as much cpu power as a dual core. Also it depends on resolution - at high res the GPU may be maxed out - so the cpu is actually waiting for the gpu before it can crunch more data - while at low res the GPU is not maxed out and will therefore call for more from your cpu (assuming vsync is not enabled).
