As are the 100%. If the application is bound by the graphics card's 
performance, the CPU cannot reach 100% utilization, since it would wait for 
the graphics card to finish drawing. 100% CPU load show, that the graphics 
card can execute drawing instructions faster than the CPU can generate them. 
Thus the application is CPU limited.
