I've replaced LAV vider decoder with potplayer video in-built D3D11 decoder.Now i decrease screen resolution to 3835*2160p.When the playback of 4k HDR movies no frame drops.
I see madvr OSD.OSD displays chroma>bicubic60 A,image<bicubic150 LA
However, when i don't decrease screen resolution anymore,Restore the resolution to orginal 3840*2160p.Frames begin to drop.At this time i see once again madvr OSD.it displays chroma>bicubic60.No image column is displayed on madvr OSD.
The both difference is just 5 pixels in horizontal resolution.
I don't understand the reason why frames drop just 5 pixels distinction between 2135*2160p and 2140*2160p
