Bitstreaming HD audio seems to work flawlessly for me as long as I use the MPC Video Decoder with DXVA and EVR. However, I much prefer the video quality with DXVA turned off, and I have to use MadVR with 3dLUT or VMR9 with pixel shaders to correct my JVC projector's wide gamut.
Whenever I use the FFDshow Video Decoder w/o DXVA the frame rate seems to hover slightly above 24fps and the audio cuts in and out and the video lags. This happens no matter if i set video card refresh to 23hz , 24hz or 60hz. The looks laggy even if I plug my DVI monitor in and leave the Onkyo off (source>ffdshow video decoder>madVR renderer and nothing else)
I have a 5770 and Onkyo 606.
Here's what I've tried so far to get it working with DXVA off:
1. catalyst 10.1, catalyst 10.2 RC2 > no difference
2. Realtek HDMI driver > no difference
3. ESVP on > seems to keep it under 24fps better, but it still goes up to 23.99 and 24.08fps and still get audio dropouts and video is still is not butter smooth like with my old 4830.
4. Tulli's Onkyo 906 override > no difference. And instead of my projector reporting 10 Bit Deep Color it only said 8-bit, so i uninstalled it, went back to my auto-created 606 and the 10-bit Deep Color color is back.
5. ReClock audio renderer > if only it worked with bitstream! This seems to play smoothly without DXVA, but obviously i dont want to listen to PCM audio, since i bought the 5xxx solely for its bitstreaming capabilities!
Is there another filter combination i should be looking at? tried different audio renderes and its all the same. audio cuts in and out and video doesnt look smooth.
My gut feeling is that I'm missing something to keep the frame rate under control with DXVA off. Any suggestions?
