Amidst losing its management staff as many times over as I lose my car key, AMD wants to point its finger at everyone. First it was at Intel over monopoly profits and now it's at Nvidia over HQV benchmarks.

Hollywood Quality Video (HQV) features true 10-bit processing, automatic multi cadence detection, and four-field per-pixel de-interlacing, and is included in nearly all HD DVD and Blu-ray players for converting standard definition video into high definition video.

AMD is saying that Nvidia cheated Silicon Optix's HD HQV benchmarks by using a driver with an aggressive noise reduction algorithm to help gain a perfect score in the benchmark's noise reduction section. This aggressive algorithm allegedally causes visible ghosting in the videos.

Both companies scored a perfect 100 in the benchmarks with their Avivo HD and PureVideo HD equipped products.

Nvidia has responded to the accusation by saying that the driver used in the testing procedure was the old ForceWare 163.11 beta version that used the suspect algorithm by default. Newer Forceware 163.44 beta drivers use a less aggressive default setting and offer could force AMD to offer adjustable settings in its own driver package.
a 0-100 percent noise reduction slider that can be adjusted by users.

As we openly told reviewers, using aggressive noise reduction settings may cause ghosting depending on the content played so we recommend using moderate settings. We also recommend the improved 163.44 driver, released a few weeks ago, which reduces this effect,” Rick Allen, Nvidia Notebook and Multimedia PR manager, told DailyTech.

The interesting point is that Nvidia does offer an adjustable noise reduction feature while AMD uses an adaptive, non-adjustable setting. This could force AMD to offer adjustable noise reduction in the future.

If you're running a video card with PureVideo HD, load up those drivers, start a HD or upscale a SD film and see if you can spot any ghosting. Tell us your results over in the forums or in the comments section below.
