madshi, thank you for a prompt response regarding my inquiries. madVR 0.88.4 is not faster for me in regards to Image Doubling and Quadrupling than madVR 0.88.2. I changed Image Upscaling from Jinc 3 tap + AR to Lanczos 3 tap + AR per your advice, but that did not help at all. Doubling + Quadrupling, both @ NNEDI3 16 neurons + NNEDI3 16 neurons for Chroma Upscaling result in SEVERE frame drops... That is WITH and WITHOUT SuperRes Chroma Upscaling filter and SuperRes Image Refinement... Using D3D11 or not using it also made no difference. Could it be just nVidia drivers? I use the latest 350.12 nVidia drivers, LAV Filters 0.65 (LAV Video uses CUVID), MPC-HC 1.7.8, ReClock
I still want to figure these out in addition to figuring out how to resolve Image Quadrupling issue: 1. What about Direct3D 11? Does it improve quality or performance? When I enable it with or without the "present a frame for every Vsync" I get presentation glitches, but no delayed or dropped frames. What are the presentation glitches? Should presentation glitches be ignored if no frames are delayed and dropped? 2. Is there any comparison or reports from people regarding the difference between SuperRes for Chroma Upscaling filter VS. SuperRes for Image Refinement. 3. Does 10bit selection for "the native display bitdepth is" work for nVidia Maxwell owners who use 8bit+FRC monitors via DisplayPort? My Eizo Foris FG2421 is an 8bit+FRC panel, but nVidia lacks an option to enable 10bit depth in its settings. Should I select 10bit anyway? To everyone else - I saw true 10bit IPS monitor gradients and my Eizo Foris FG2421 8bit+FRC panel gradients do not look as good, but my panel has 4700:1 contrast ratio after calibration. In the end, I DO think true 10bit panels show better gradation than 8bit+FRC monitors. Its like saying that 6bit+FRC TN panels are as good as true 8bit IPS panels in regards to gradation (not everything else though). On my FG2421, there is some "banding" visible in darker grayscale levels when I use ArgyllCMS 1D LUT for desktop/games, but its not so much banding as the actual dithering pattern that changes. I don't really like it to be honest. It makes it impossible to get a real accurate 1DLUT calibration, especially for darker gray levels. The dithering itself only works if the pixels turn a different color, one that is not accurate for that grayscale level, again, making it impossible to truly calibrate. 3DLUT is probably less affected since its being processed at higher bitdepth, but that dithering is ALWAYS there. I use dispcalGUI 3.0.0 with ArgyllCMS 1.7.0 x86 and i1Display Pro colorimeter. Last edited by XMonarchY; 12th May 2015 at 00:38. |

even with a artificial ramp that looks like this in 8bit w.o dither http://i.imgur.com/zzSpKR7.jpg dither on vs 10bit FSE, at a glance, I have no way to tell difference. Last edited by baii; 12th May 2015 at 00:50. |

Sorry, I did not test 0.88 yet, since i did not have time to read bug reports, etc.
I just wanted to know if it's a 0.87.21 known bug. With x64 build of 0.87.21 (and not x86), even if I disable "switch to matching display mode", madVR automatically changes refresh rate. Instead of 60Hz (define in Windows before launching movie), it automatically switches to 59Hz when I enter Fullscreen. I saw it because my TV becomes black and TV OSD shows resolution/refresh rate (even if it writes 60Hz instead of 59). With madVR stats, it's easily confirmed. I think I'll test 0.88 tomorrow, but if someone would confirm it was a known bug, it would be nice. PS: I've installed latest Beta Catalyst driver to be sure it was not drivers related, but it's the same problem. Last edited by pirlouy; 12th May 2015 at 00:56. |

v0.88.4 is running very well for me and I like the new D3D11 support a lot - it allows a faster transition into and out of FSE.
edit: no performance hit with SLI on when using D3D11! FineSharp is also quite nice for some content. Thanks for these major updates! Of course, at some point in the future, it would be great to have profile support for "image enhancements" and "upscaling refinement".

I seem to be getting 10-bits only when my display is at 60Hz. When at 23Hz, I don't seem to be getting the 10-bit output.
I am using the following pattern in mpc-hc x64: http://forum.doom9.org/showpost.php?...8&postcount=11 win7x64, gtx970 connected to 10-bit TV via HDMI 2.0. At 60Hz dithering disabled, I see a smooth pattern. At 23Hz dithering disabled, I see the same banding 8-bits and up. I am not sure who is at fault, madvr, nvidia or TV? Any ideas? Does anyone successfully produce 10-bit output in 23Hz? |

oops! you are right, they are profileable now.
Thanks.

rendering vs present finesharp vs superres
Experimenting with the image enhancement and upscaling refinement settings it seems FineSharp and SuperRes provide similar image quality improvements to each other. The two together provide too many artifacts, so it seems (at least on my system) that its best to choose one or the other. SuperRes seems to provide slightly higher render times and faster present times while FineSharp has faster render times with higher present times. Given the 480 video upscaled to 1080 resolution I was testing there was only a small swing either way (SuperRes 15ms render 9ms present, FineSharp 8ms render, 12ms present). What are opinions on which is the better to keep low(er), or allow to drift high(er).
Edit: Tested 720p video upscaled to 1080p also. Finesharp was ~11ms on both render and present while SuperRes was 20ms render and 8ms present. Based on that I'll probably go with Finesharp for the moment.

something isn't working as it should i guess. you should usually have avg present times below 1 ms... i usually have avg present times below 0.2 no matter what settings are used. how are your present times with other presentation modes like old path or overlay? |

I'm having a small problem using D11. My refresh rate changes from 59.99 in windowed to 59.93 in FSE, which makes the transition somehow slow.
This happens on my TV, and not on my monitor. I tried with the TV as main screen and it happens the exact same way. With D9 no problem. |
