[QUOTE="RonD, post: 1101017, member: 117536"] Bottom line for my test system Laptop: CPU = IvyBridge, i3-3237U 1.90 GHz, 2 core 4 thread, Intel HD4000 GFx Win8.1. DXVA(copyback) is worse than no HW acceleration. Copyback is about CPU = 75-80%, AVCODEC is about CPU = 45-50%. Test video is 1080i 1920x1080 about 17 Mbps, My USA ATSC channels are between 17-7.4 Mbps 1080i or 720p. depending on network and number of ATSC subchannels. Discovered that Msft Process Explorer (google for download) can show a little more detail on GFx engine and shows 2 GFx engines on my HD4000 system. With Msft Process Explorer, View > System Information brings up performance charts. Select GPU then Engines to see per GFX Engine chart. Hover mouse over chart to see numbers. Attached png shows output for MePo1 LAV/DXVA(native) active. Not sure what GFx5 GFx6 really do. Looks like GFx5 handles MePo1/2 GUI activity and video. GFx6 is active when HW acceleration running. Just windows plus 3 perfmon tools, CPU = 5-10%, GPUz = 0%, ProcExpGFx Eng5 = 2-5%, Eng6 = 0%. Each perfmon tools uses 2-3% of CPU. TaskManager, ResourceMonitor, ProcessExplorer, GPUz. Start MePo1/2, fullscreen, idle GUI in videos window, LAV = not active, CPU = 10%, GPUz = 60-70%, ProcExpGFx Eng5 = 60-70%, Eng6 = 0% MePo1, CPU = 45-50%, GPUz = 64%, ProcExpGFx Eng5 = 65%, Eng6 = 0%, LAV = none/AVCODEC MePo1, CPU = 15-20%, GPUz = 60%, ProcExpGFx Eng5 = 60%, Eng6 = 20% LAV = DXVA2(native) MePo1, CPU = 50-55%, CPUz = 65%, ProcExpGFx Eng5 = 65%, Eng6 = 10%, LAV = DXVA2(copyback) MePo1, CPU = 45-50%, CPUz = 70%, ProcExpGFx Eng5 = 68%, Eng6 = 12%, LAV = DXVA2(quicksync) quicksync has Audio/Video sync problem MePo2, CPU = 55-60%, GPUz = 90%, ProcExpGFx Eng5 = 90%, Eng6 = 0%, LAV = none/AVCODEC, MePo2, CPU = 55-60%, GPUz = 90%, ProcExpGFx Eng5 = 90%, Eng6 = 0%, LAV = DXVA2(native), LAV shows AVCODEC MePo2, CPU = 75-80%, GPUz = 97%, ProcExpGFx Eng5 = 97%, Eng6 = 12%, LAV = DXVA2(copyback) MePo2, CPU = 55-60%, CPUz = 96%, ProcExpGFx Eng5 = 96%, Eng6 = 12%, LAV = DXVA2(quicksync) quicksync has Audio/Video sync problem [/QUOTE]
