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 |

Theoretically the situation should not have happened just 5 pixels distinction in horizontal resolution.Only explanation is that the image downscaling algorithm can bring down CPU load(usages). What do you think of my explanation? |

As I said, upload them to an image host
https://imgbb.com/ is a good one, select 'bbcode full linked' and paste the code shown below in the forum. |

I will have it on Monday and would like to be prepared ) PC : CPU: I7-7700K OC 5.1GHz ; GPU: Gigabyte GeForceŽ GTX 1080 WINDFORCE OC 8GB ; MB: Asus ROG STRIX Z270H ; Cooling: Arctic Liquid Freezer 240 ; Memory: Corsair Vengeance RGB (2X8GB) DDR4 3100MHz, ;SSD: Corsair MP500 240GB NVMe (PCIe)+Samsung Evo 850 Pro 256GB ; Case: NZXT H440 ____ THANKS!

It is really a matter of preference. Delay playback until the render queue is full and D3D11 for presentation are the only obvious settings. You would have to try the others.

I would avoid Error Diffusion dithering for your 4K profile, especially if you are outputting at 10-bits. This eats up a lot of processing for very little.
