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_1_unaccel is 20.2 % less load for CPU_0_accel. In both cases the another corresponding core is practically off, and there is no difference between them. | In the chart above, is clearly shown that when using hardware acceleration, a substantial reduction in CPU workload is achieved.

In the chart above, it can be seen in a general way that in both cases, the frame-rate reaches the expected value of 30 fps and then remains stable. | |||
