The duty cycle in BurnInTest doesn't equate to a % loading as displayed in the task manager, at 100% the test runs as fast as it can and decreasing the duty cycle will increase sleeps into the tests so they spend more time sleeping and less time executing, see here for more details.

Most systems with CPU and 3D at 100% will see near full use of the CPU, maybe the integrated GPU is taking resources from the CPU and slowing it down.
Do you see 100% use if you just run the CPU test?

HI

BurnInTest only tests CPU 100%, which can be seen as 100%. Testing 50% is floating up and down, which will rush to 50%
