Blu-Ray High Definition content demands a lot of PC processing
resources during playback, if CPU load becomes too high that can lead to
jittery video quality or other artifacts. Many integrated graphics
processors now feature Blu-Ray and High Definition H.264, VC1 and M-PEG2
content acceleration decoders to offload this processing from the CPU,
freeing up system resources for other tasks.
The PCSTATS Blu-Ray HD content playback test scenario monitors average
CPU utilization. It's simple and to the point. The motherboard's
integrated graphics processor is taxed in the same way it would be in your
home theatre environment, and average percent CPU utilization monitored
with Windows task manager. Lower CPU utilization values are best, provided
video playback remains smooth and stutter free.
How PCSTATS Tests:
Each integrated graphics motherboard is connected to an ASUS
MK241 wide screen 1920x1200 (1080P) resolution LCD display
with an HDMI cable. The Blu-Ray movie "10,000 BC" (VC1 encrypted)
is then played back from Chapter 22 on an ASUS BC-1205PT Blu-ray combo drive,
using WinDVD Platinum software and the
average fluctuation of CPU load recorded.
(The ASUS MK241 supports HDMI-audio, so sound quality is monitored on
the speakers, if motherboard is able to output HDMI-audio.)
