http://download.microsoft.com/downlo...global-enu.exeI just got word that Microsoft has finally put out a patch to WMP10 to properly enable WMV-HD acceleration for graphics cards that support it.
This update enables Microsoft DirectX Video Acceleration (DXVA) of Microsoft Windows Media Video (WMV) content in Microsoft Windows Media Player 10 for video cards when the drivers of those video cards are designed to take advantage of this featureI ran some tests on my demo system with the “Step_Into_Liquid_720.wmv” WMVHD clip that can be downloaded from the Microsoft website and have observed the following improvements with a 6600 Passive:
Without WMV patch: 64% CPU Utilization
With WMV Patch: 40% CPU Utilization
I also ran the same tests with the 1080p version of the same demo clip and have observed even better improvements:
Without WMV patch: 98% CPU Utilization (and dropping frames)
With WMV Patch: 57% CPU Utilization (no dropped frames)
