Games that used up 6 or 8 cores 90%+load

Solution
None. Most work is done in two threads: The main game executable, and the main render thread. A few engines, such as CryEngine 3 and Frostbite 3 can use additional GPU render threads for slightly better scaling, but two threads still dominate because most of the workload is serial, not parallel.
