Just upgraded from Vista Ultimate x64 to Win7 Ultimate x64 and something I noticed afterwards is now I can enable DXVA under "Enable GPU acceleration" in common settings but haven't tested with it yet, might help the Vista users if Fengtao or ting wants to compare notes on the 2 systems. (just thought I'd mention it) my card is a NVidia GeForce 9500GT as posted in the GPU chipset results thread.
