i go install 87.21 do some screens (found the video i did these chroma doubling/quadrupling test month ago) and than test your new 88 build. nedi totally fails for pixel art by the way. |

Jinc3 AR does cost a lot more performance than Catmull-Rom AR. The difference should be noticeable even on a fast GPU. It might not be a night-and-day difference, but even saving 2-3ms can help if you want to use other algorithms, as well. |

NEDI works ok for pixel art, when combined with SuperRes. Without SuperRes it totally fails, that's true. |

- Rendering times are about 20-22ms when I set Chroma Upscaling to NNEDI3 32 neurons, and Image (BOTH LUMA AND CHROMA) Doubling + Quadrupling to NNEDI3 32 neurons. No frames are dropped. - Rendering times are about 18-20ms when I set Chroma Upscaling to NNEDI3 32 neurons, and Image (ONLY LUMA) Doubling + Quadrupling to NNEDI3 32 neurons. No frames are dropped. - I do not get the same results with build 88.5. Please see below. Quote:
Original Settings - Rendering times are about 20-22ms when I set Chroma Upscaling to NNEDI3 32 neurons, and Image (BOTH LUMA AND CHROMA) Doubling + Quadrupling to NNEDI3 32 neurons. No frames are dropped. B) With build 87.21 (new 88.5 features not available in this build, Image Upscaling is set to Lanczos 3 tap, and FSE to disabled): Chroma Doubling + Quadrupling disabled - Rendering times are about 18-20ms when I set Chroma Upscaling to NNEDI3 32 neurons, and Image (ONLY LUMA) Doubling + Quadrupling to NNEDI3 32 neurons. No frames are dropped. C) With build 88.5 (ALL new features turned off, Image Upscaling is set to Lanczos 3 tap, and FSE to disabled): - Rendering times are about 18-20ms when I set Chroma Upscaling to NNEDI3 32 neurons, and Image Doubling + Quadrupling to NNEDI3 32 neurons. No frame drop this time! I even went back and set Image Upscaling to Jinc 3 tapm, enabled the Shiandow's Deband Algorithm, and enabled SuperRes filter for Chroma Upscaling and it produced no frame drops! Quadrupling issue is SOLVED with 88.5! . Using SuperRes fot Image Refinment in addition to settings above resulted in frame drops, but as you said - those settings are only for testing.

Will you be adding 60 frames to render ahead for Windowed and Fullscreen now that D3D11 can sync to the VSYNC rate? Or am I misunderstanding the whole D3D11 mode that was recently added?
I've found setting Windowed and Fullscreen to 16 and GPU que to 16 with CPU que at 20 provides very low ms (10-20 ms) playback. |

Anyway, I created 2 clips, one with Bandicam and one with my compact digicam. P.S. That half a second black screen is because I restarted playback with Ctrl + E. I also noticed that Render Queue is not full in D3D11 mode although rendering times are low but I can't remember if I saw that under Windows 8.1. No big deal. I just wanted to try D3D11 for better performance. I don't need 10-bit output or so. Madshi

http://www.monitortests.com/forum/Th...on-Utility-CRU It lets you set what resolutions your display is allowed to use. Once setup correctly, you can make your display only be allowed use 60hz for example by removing the other ones you don't want to allow. This worked for me with a bit of fiddling. |

No. As i said earlier, I already had this problem with 0.87.21 (no D3D11 if I understood correctly).
I noticed the problem with x64 build since the 64 build switches to 59Hz. I never noticed the problem with x86 builds before because in fact the x86 build auto switches to 60Hz and I was already in 60Hz. I don't know if I'm clear but: With x86 build ; desktop to 59Hz; No D3D11; launching file; goes into FullScreen Exclusive --> Switches to 60Hz With x86 build ; desktop to 60Hz; No D3D11; launching file; goes into FullScreen Exclusive --> No Switches With x64 build ; desktop to 60Hz; No D3D11; launching file; goes into FullScreen Exclusive --> Switches to 59Hz With x64 build ; desktop to 59Hz; No D3D11; launching file; goes into FullScreen Exclusive --> No Switches. But during my extensive tests today, I've most of all noticed Fullscreen Exclusive causes dropped frames and other nasty things. For now, the windows renderer is way better for me. But I don't think it is linked with 0.88 since it is the same if I don't use D3D11. Last edited by pirlouy; 13th May 2015 at 00:39. |

If I only have 1080p24 (or 1080p23 for that matter) in the setting box, every video that goes to fullscreen will turn the TV to 1080p24 mode regardless of source fps. You say this shouldn't happen right? I use madVR v0.87.21, and a bit older MPC-HC (for a reason) v1.6.9.7418 Lite, not sure this is the culprit.

After some tests, here is what I've noticed with 2-3 minutes from the same movie.
From best config to worst madVR x86, No Fullscreen exclusive (windowed), No D3D11 (D3D9): 0 frames dropped/glitches madVR x64, No Fullscreen exclusive (windowed), No D3D11 (D3D9): 2 frames dropped/glitches madVR x86, Fullscreen exclusive, No D3D11 (D3D9): 5 frames dropped/glitches After, all configs have problems, did not really count, but D3D11 adds dropped frames/glitches, not as much as FullScreen Exclusive+64 bits though. And so the worst config is: madVR 64 bits, Fullscreen exclusive, D3D11: 50 frames dropped/glitches Some comparison with madVR 0.87.21: madVR x86, No Fullscreen exclusive (windowed): 0 frames dropped/glitches madVR x64, No Fullscreen exclusive (windowed): 0 frames dropped/glitches madVR x86, Fullscreen exclusive: 1 frame dropped/glitche madVR x64, Fullscreen exclusive: 10 frames dropped/glitches Sorry I read you wanted feedback on debanding for now, but I had some time to do tests, and I'm not interested at all by upscaling/debanding/dithering, I'm not strong enough to notice image quality.

I take this phrasing to mean that chroma is doubled to match luma, the video is converted back to RGB, and then downscaled with image downscaling (assuming a <2 scaling factor)? Sorry if I am reading too much into your choice of words.

A trade quality for performance checkbox that forces Catmull-Rom chroma scaling would make sense. NNEDI3 is meant to be the best of the best scaling algorithm. If the opposite logic was used, place a checkbox next to Image Doubling that allows for Jinc3 chroma scaling. Either way, it is only one checkbox. Last edited by Warner306; 13th May 2015 at 04:25. |
