I don't have a high cpu load problem with DXVA2(copy-back).I have jerky ''skippy'' slow down playback problem with DXVA2(copy-back).Only with HEVC,other sources play smoothly with DXVA2(copy-back).

Guys sorry but I didn't know that it wasn't Madvrs fault.For dxva(copyback) I'm going to Lav thread but DXVA2(native)HEVC black screen points Madvr and AMD users.EVR plays 10bit HEVC with DXVA2(native) as intended,no black screen.Two more AMD users here reported it.
Madshis priority is NGU pixart,not that.All I said is to keep it in mind.Have a nice day Last edited by Damien147; 23rd February 2017 at 11:09. |

I just tested two HEVC 2160p 60 fps samples on my RX 480 out of curiosity. Results:
1. HEVC 2160p 60fps 8-bit (link in the description): madVR, DXVA native - All good madVR, DXVA copyback - Slideshow EVR CP, DXVA native - All good EVR CP, DXVA copyback - Slideshow 2. HEVC 10-bit 59.940fps (Korean ATSC 3.0 satellite TV capture sample): madVR, DXVA native - Black screen EVR CP, DXVA native - All good Conclusion: The slowdown is not madVR related. The black screen probably is, OSD reports P010 plus a lot of dropped frames and presentation glitches. Last edited by MS-DOS; 23rd February 2017 at 20:01. |

Unsurprisingly, I don't have 50hz among the allowed one for 2160p in my TV/video card/driver. |

Tested and yes, it seems like the third variation does a pretty good job at eliminating the aberrations from the old pixart module. I would personally prefer maybe even more anti aliasing if that were possible as I like my images very anti aliased for anime, but I think that it is going in the right direction. Too much sharpness can easily result in jagged edges with anime, especially when we're talking about old shows, bad encodings and such.

Too bad because I found source to reproduce your problem (25fps movie with 30hz) and If I added p50 solved it{(particular 25fps sources playing in 50hz)(other 25 fps sources played in 25hz)} |

That the "slideshow" is worse with madVR compared to EVR is expected, madVR uses more memory bandwidth than EVR. If copyback is noticeably slower than native your GPU is starved for memory bandwidth.
