Found a bug. In the scaling algorithms profiles, I have this defined.
if (targetWidth <= 1366) && (srcHeight <= 300) "Laptop 288p" else if (targetWidth <= 1366) && (srcHeight <= 480) "Laptop 480p" else if (targetWidth <= 1366) && (srcHeight <= 768) "Laptop 720p" else if (targetWidth <= 1366) "Laptop 1080p" Playing 1080p videos select "Laptop 720p"! If, however, I replace srcHeight <= 768 by srcHeight < 769, then it selects "Laptop 1080p". There seems to be something wrong with the <= operator or something around there. I'm using the .11 version that was just released. Edit: There's still something random to it. With that edit, it still sometimes select "Laptop 720p" but much less often. To know which one is selected, I open madVR settings and look which one is in bold. I seem to be getting a more consistent 1080p selection by putting condition srcHeight < 760 Edit2: I'm seeing that SVP has an option that decreases the image to the screen size, which means madVR doesn't see it as a 1080p video but rather as a 768p video. If any additional cropping is applied, then the resolution ends up being even smaller. This might be related to the issue.

I've heard many times how NNIDE3 is so GPU-intensive. Am I missing something or is it LESS demanding than Jinc?
While playing a 1080p video on 768p screen, I'm getting these rendering times with chroma upscaling Jinc 3-taps AR: 7.7ms Jinc 4-taps AR: 18ms NNEDI3 32 neurons: 7.6ms NNEDI3 256 neurons: 7.7ms I have a Radeon HD 7660M on Windows 7 x64 So basically the highest settings I can have to play 1080p on 768p display with SVP + madVR still leaves half of my video card unused (as I can go up to 16ms rendering time)

There are two places where NNEDI3 can be selected. In Chroma Upscaling, or as you're saying, in Image Doubling. I'm not seeing a significant cost for Image Doubling either. It only affects smaller videos that are lighter to process anyway.

MadVR reads the resolution from upstream filter, not the file. Just check the OSD (CTRL+J) to see what madVR gets your video as. |

you are not even using jinc in this case because jincs in madVR can't downscale too. the only way to use nnedi3 with a 1080p source on a 786p is through chroma scaling same with jincs. and to make things clear 1080p on a 1080p screen is very simple while 480p - 720p source on a 1080p screen takes a lot more processing power. of cause i'm only talking about the work madVR has to do we are in the madVR thread. |

The reason may be that NNEDI3 dont use extra AR feature, thats whats slowing your machine in Jinc 4 AR i suppose |

That's not what his results show though. vivan is correct that NNEDI3 is not being used on MysteryX's system. Since his results are identical, it means OpenCL is broken and madVR is silently falling back to a different upscaling setting. NNEDI3 chroma upscaling is relatively expensive on 1080p video, so there is no way he could have render times less than 8ms on a AMD 7660M even with NNEDI3-32.

Hello! i really love MadVR it just gets better and better! but one thing is missing! a seekbar inside the picture area like in a 2.35:1 movie. Why i wonder is because i'm about to order a 2.40:1 screen!

For chroma upscaling, it is probably silently falling back to Jinc 3-taps AR since rendering times are the same. Still... I'm pretty such there is a slight quality increase, unless it's a psychological effect.

there has to be a reason why openCL doesn't work on your system. a 7660m can use openCL that why I miss judge the situation and guess you where trying to use image double because the rendertimes didn't changed. there is simply no reason madVR wouldn't use it for chroma. if you haven't tried it yet install new driver. and what OS are you using right now? |

I'm using Windows 7 64-bits. Radeon HD 7660M. As for drivers, I'm using LeeKM's modded driver v14.200. It's more stable and faster than any other driver I've tried. Unfortunately, as far as I know, none of LeeKM's more recent drivers support this graphic card. The latest Samsung-approved dual-graphics driver is very old with much lower performance, and although installing the latest driver directly from AMD works for my system, it doesn't work better than this version so I always end up reverting back to this one.

I just updated to the latest AMD drivers: 14.11.2 Beta (I'm surprised those are working out of the box on a dual-graphics system, but somehow it does)
NNEDI3 still doesn't work.

With this latest driver, I still get tons of dropped frames on a 1080p TV with a rendering time of 7ms. However... only 1080p videos on 1080p display. 720p videos play fine with 15ms rendering time.
