NVIDIA Enables PureVideo on GeForce 6 GPUs

Not so Ultra: No Decode Acceleration on NV40 and NV45
As we mentioned before, PureVideo is only partially functional on NV40 and NV45 (GeForce 6800 Ultra and 6800GT, AGP and PCIe), all of the de-interlacing and image quality functionality is there, however those GPUs do not have any WMV9 decode acceleration which is made evident by the performance comparison below:
| NV40/45 vs. NV43 - WMV9 HW Accelerated CPU Utilization (Lower is Better) - VMR9 Window | |||
| Minimum | Average | Maximum | |
| NVIDIA GeForce 6600GT | 7.7 | 16.6 | 24.2 |
| NVIDIA GeForce 6800GT | 18 | 31.6 | 43 |
| NV40/45 vs. NV43 - WMV9 HW Accelerated CPU Utilization (Lower is Better) - VMR9 Full | |||
| Minimum | Average | Maximum | |
| NVIDIA GeForce 6600GT | 5.5 | 17.3 | 24.2 |
| NVIDIA GeForce 6800GT | 18.8 | 34.2 | 49.2 |
Remember that this only applies to the NV40 (GeForce 6800GT/Ultra AGP) and NV45 (GeForce 6800GT/Ultra PCIe), NV41 (GeForce 6800) has fully function WMV9 decode acceleration.

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?
