+In the chart above, is clearly shown that when using hardware acceleration, a reduction in CPU workload is achieved. The average difference between CPU_1_accel and CPU_1_unaccel is 9.27% less load for CPU_0_accel. In both cases the CPU_0 has a very similar average workload percentage, so there is no significant difference between them.
-In the chart above, is clearly shown that when using hardware acceleration, a substantial reduction in CPU workload is achieved. The average difference between CPU_0_accel and CPU_0_unaccel is 49.2% less load for CPU_0_accel. The average difference between CPU_1_accel and CPU_1_unaccel is 39% less load for CPU_1_accel.
