    Anyone knows any benchmark or review about image quality when using DXVA acceleration on both ATI and NVIDIA cards? :eek:

    I'm asking this because i recently brought an E-350 APU based notebook (Radeon HD 6310). I found that 720p H264 vids play very smooth but image quality is worst compared to GT 240M featuring VP4 on my old laptop :confused:. This was clearly visible.

    Unfortunately the laptop was not for me and i have't so much time to take screenshots in order to compare. Maybe UVD3 use some trick/performance algorithm to achieve smooth playback? :eek:

    Sorry for my not-so-elegant english :eek:

    Video quality between the two is supposed to be the same. What program are you using to play the video?

    Same and updated version of MPCHC. You think that should be the same because DXVA involves directx?

    All H.264 decoders are required to output the exact image, so it's supposed produce identical video to meet the standard.

    Have you tried disabling image enhancements like noise reduction and dynamic contrast in ATi/AMD Catalyst Control Center?

    When i disabled the image enhancements Catalyst uses by default it made a huge difference.
