A Preview of the Future - Fully Hardware Accelerated HD Decode
NVIDIA sent us elements of a forthcoming update to Windows Media Player 10 that will further take advantage of PureVideo's hardware acceleration. At the same time, ATI sent us information on how to enable hardware acceleration of WMV9 on their cards before the forthcoming WMP10 update.
To enable WMV9 Hardware Acceleration on ATI X series cards see the following note from ATI:
Note: WMV9 acceleration has been disabled until Microsoft issues a new patch for WMV9. To enable this with other versions of Catalyst (with some rendering errors), RUN regedit -> HKEY_LOCAL_MACHINE -> SYSTEM -> CurrentControlSet -> Control ->Video and find your ATI reg value. The key to update is DXVA_WMV = 1
The improvements are nothing short of impressive, full hardware decode acceleration cuts CPU utilization almost in half for both vendors.
| WMV9 HW Accelerated CPU Utilization (Lower is Better) - VMR9 Window - 720p Terminator Trailer | |||
| Minimum | Average | Maximum | |
| ATI | 10.9 | 17.8 | 24.2 |
| NVIDIA | 7.7 | 16.6 | 24.2 |
| WMV9 HW Accelerated CPU Utilization (Lower is Better) - VMR9 Full - 720p Terminator Trailer | |||
| Minimum | Average | Maximum | |
| ATI | 3.9 | 17.9 | 24.2 |
| NVIDIA | 5.5 | 17.3 | 24.2 |
Full screen decode performance is much more manageable at under 18% for both GPUs.

This is pretty interesting and since I already bought the Nvidia DVD Decoder I can upgrade to this new version if the link on Nvidia's site ever starts working lol.jonny13 - Monday, December 20, 2004 - link
"Considering that PureVideo came as a free feature on GeForce 6 cards"How is paying $20 for the damn codec free?
