Thank You !!!
v0.87.5 is a big step up in madVR's image quality. Considering we only had random dithering which is clearly visible even in 8bit, compared to any of the new options which are barely visible to invisible. P.S Bug #167 "dithering produced dithering noise on pure black areas" still exists. This bug was only apparent when 3DLUT or yCMS where active, unlike the dithered Whites (even without 3DLUT) with ATI card which is a different (real) bug altogether. @6233638 Might I add that its not actually a bug, its a side effect of the calibration (0.000015746 instead or pure 0.0000000000 for black). It can be solved by moving the blacks to -1 in madVR.

Wow, looks like a lot of bug fixes in this build.
Does this build sync dithering to the video framerate now to prevent flickering? I didn't see it mentioned in the release notes. I know that you're not taking feature requests, but would it be possible to have a keyboard shortcut toggle "disable GPU gamma ramps" ? Now that I can use the feature to bypass the display LUT (or not) in overlay mode, it would be quite useful to have. |

When running on older cards, it just silently falls back to ordered dither, afaik.

Madshi, can i know why do you prefer 7xxx series over the new series?
THX-UltraII can i know how much NNedi32 chroma upscaling neurons can you set, without dropped frames, with your r8? And with image doubling? Naturally i am talking about bluray 1080 24p material. Thank you |

Personally I see the r9 270 as the sweet spot for HTPC usage, but opinions might differ. The r9 270 can easily run Jinc3 AR for scaling, Error Diffusion and Debanding with maximum quality settings. If you want NNEDI32 doubling combined with those, you might need a more powerful GPU (unless madshi/AMD manages to reduce OpenCL interop costs ). Last edited by Gagorian; 5th March 2014 at 20:25. |

I just succeeded in recreating the 'blinking' effect by just replacing the video with noise. As far as I can tell it is a limitation of the screen. In my case I suspect my screen takes too long to get to full brightness so the frame that is shown longer gets brighter. In theory this shouldn't happen with screens with particularly low latency, like projectors or CRTs. Smooth motion should also help, but that doesn't seem to be the case.

would i still get a 7xxx or should i get a 280x/290/290x? most source material is 1080p24 so i honest don't know what i should buy.. i will spend alot of time testing everything out later on but my knowledge around it all is very limited so i will be back i will get it ISF calibrated and i will probably use some filters and pre/post processing...

w00t new build,

One thing you could do is input those figures in this script and if you're lucky the gamut coordinates wouldn't be too far off. Two things come into play IMHO: 1) It's often better to be one generation late with computer parts, much higher bang/bucks most of the time and due to Moore's law improvements aren't quite giant steps anymore. 2) the new line-up is mostly rebranded chips, I believe they only bring Mantle to the table and AMD is well aware that they kill nvidia in raw OpenCL performance so street prices are pretty high now. I see 2GB 7870's sold for 99€ shipped around here and 3GB 7950's for 125€, these boards will make your day in mVR at 1080p. No idea about 2160p but if you wanna crank 64x NNEDI, you will need something faster than a 7950 IMHO. Last edited by leeperry; 6th March 2014 at 00:55. |

Hello,
A long time lurker, since the first post. I try and follow the thread best I can but am not very technical. I've just updated to v0.87.5 and tried image doubling default values and get a mostly black screen when on full screen, with some reds and blues showing. I read the line in the changelog: * error diffusion now uses DirectCompute (DX11 GPU needed) instead of OpenCL Does this mean NNEDI3 image doubling now works with Nvidia gpus. Mine is a GTX 670 Win7 x64 Zoom Player 8.7 b33 Lav filters 0.61 (DXVA2 - native) NV GTX 670 (drivers 331.82) Plasma 50 inch via HDMI Playing 99.9% MKV 1080p and 720p TV shows/movies but was just trying the image doubling out for the first time on a 720x476 mkv (Star Trek Voyager) Usually use: Chroma Jinc 4 (AR) Image upscaling Jinc 4 (AR + SLL) Image downscaling Catmull-Rom I did change image upscaling to Lanczos AR as Madshi suggested some pages back when NNEDI3 was introduced. Do I have to wait until Nvidia fix something in the drivers, or do I need to change some MadVR settings in this new release to get image doubling to work. Seems what ever I do, once I go full screen its just black with some reds and blues showing. Then crashes zoom player. Could I ask for guidance here please.

In general it won't need to dither anything when madVR is used, as long as you didn't disable any output formats in LAV.
