I just experienced my first random white pixels veil due to overheating on my 7850 huh(the 20% fan speed cap apparently has its limits), all was well until I tried NNEDI 32x for chroma and things went bananas...2:30AM is way too late for me to compare it against J3AR anyway
All this said, your Asus 660 has become a benchmark when it comes to silence...can it do the following on 1280x720@24 please? Chroma: J3AR(possible NNEDI 32x) Image Up: J3AR Image Down: CR+AR+LL NNEDI 64x luma doubling low debanding A4 mono-static LL dithering PS script on top of it I realize that the 660 scores poorly in pure OCL benchmarks but the AMD interop lag divides the results in outrageous proportions and your 660's silence blew me away while I briefly owned it |

Just reporting in to say the OpenCL registry tweak does the trick for my HD 4000 / GT 650M.
Now I have the option for 480p23 -> 1080p to go Jinc3+AR or NNEDI3 16 neurons doubling+Lanczos3+AR. More intensive, and rendering times are too high. Hrms. Choices, choices. Both are good ones, fortunately. |

I think I found a pretty serious bug.
Setup: Windows 8.1 madVR 0.87.9 MPC-HC 1.7.3.185 Nvidia 335.23 ReClock 1.8.8.3 Xy-SubFilter 3.1.0.687 MadVR Settings: Debanding low, NNEDI3 32 chroma, NNEDI3 32 luma doubling, Jinc 3 upscaling, CR AA LL downscaling FSE, Seperate device for presentation, queues 24/20/16, SM FRC 'only if judder' ED option 2, colored noise, change every frame No trade for quality options checked. Issue: Playing back content not in native aspect ratio of monitor plays content outside monitor resolution. In other words, rendering / upscaling larger than monitor supports, cutting subtitles and picture detail. Not fully fitting the image inside the resolution. I have a 2560x1440 (16:9 aspect ratio) monitor. Examples playing SD content. (4:3 and other, not natively 16:9) Had to disable FSE mode to take screenshots. Native 16:9 content upscales fine and doesn't have this issue. Here are two examples with 720p and 1080p images to 1440p. I apologize, I do not know when this bug began to occur, as I only recently began watching older SD content. I do know I never use to have this issue about 8 months back. Is there a way to force target rectangle to monitor's resolution so content can maintain aspect ratio inside display's aspect ratio to avoid stretching and displaying 'out of bounds', losing detail? |

Are you sure you didn't mess with your player settings to cause this?
For example, MPC-HC should be set to Video Frame -> "Touch from inside" and "Keep Aspect Ratio", as well as Pan&Scan should be off (use "Reset" to clear any settings). Sounds to me like you have it set to "Touch from outside" instead.

for people like me with crap gpu's and not much (or any) expendable income (i.e.: me). fse provides much more stable performance with far less frame drops/presentation glitches (at least on my rig) - currently running an ancient geforce 8400gs on windows 7 64bit and can play back even high bitrate blu ray encodes beautifully (albeit with mostly the lowest settings). thanks a trillion times over to madshi!

Only DXVA2 is supported by madVR, which generally requires Windows Vista or newer.

I still can't get my head around how 4 GB/s is limiting the performance of the video card when using NNEDI. It must be a very poor/slow implementation on AMD's part for the OpenCL/Direct3D interop, an issue they apparently don't have when it is DirectCompute/Direct3D. At least I can still watch DVD/480p content using luma doubling/quadrupling, where it makes a bigger difference. Since my computer is relatively modern and high spec, I never thought I would run into an issue like this I just don't see AMD fixing this any time soon, if ever.

If that is what is actually happening then it sounds like it goes through some emulation layer or something. A very bad idea/implementation for their part.

So how do 660's score with NNEDI then? Anyone's with a 660 around please? Last edited by leeperry; 4th April 2014 at 14:37. |

has the OpenCL rendering dialog moved to general settings? (use OpenCL to process DXVY NV12 surfaces)

This option is only used if you're using DXVA Native decoding. It speeds up rendering in some cases. |

63 nerons and 720p, or 32 neurons and 1080p?
NNEDI3 behaves strangely depending on the neuron and scaling combinations IMO. For example I have two of the same video I was testing it with - one a 480p version, and the second a 720p version. If I set NNEDI3 chroma upscaling to 63 neurons and expand the video to full screen (1920x1080) it runs fine with no dropped frames, but if keep the settings the same and play the 720p version at full screen (again 1920x1080) it drops frames like crazy. I would think it would be more work for it to upscale the 480, but that doesn't seem to be the case. I don't suppose its a bug, is it? Anyone care to explain why upscaling from 480 to 1080p is easier for it to do than upscaling from 720p to 1080p?
I've come across two options to prevent dropped frames given the situation (since going in and changing the neurons every time I want to watch a 720p video is impractical). One is to add 720p60 and 720p59 to devices (its the built in notebook screen, so 60hz and 59hz are the only settings it accepts) -> name of screen -> display modes -> list of all display modes madVR may switch to: area in madVR settings (in which case no up-scaling is done, but video playback quality isn't as good (more blurry looking) since its not the screens native resolution. The second is to turn neurons down to 32 from the 64 (and leave the 720p options off the switchable display mode settings) which also causes a drop in visual quality. Which do you think is the better way to run? Leave NNEDI3 neurons at 64, and allow screen sizing of 720p, or drop to 32 neurons and keep everything upscaling to 1080p?

More input pixels takes more time - similar, more output pixels would take more time (ie. higher target resolution), but if the target resolution is the same, smaller source video is just faster, because it has less input to process. Quote:
Instead, setup profiles! Setup one profile with 64 neurons for SD content, and a second profile for 32 neurons for 720p content. Problem solved!

I right clicked on scaling algorithms, and clicked the create profile group button (and checked the box for chroma upscaling). (A new folder appeared which I named "upscaling per content") In that new folder there were two folders (named Profile 1 and Profile 2), I renamed the top to "480p" and inside that I set chromas upscaling to NNEDI3 and 64 neurons. I clicked on the button that says edit shortcut and pressed "4". I renamed the bottom Profile to "720p" and inside that I set chromas upscaling to NNEDI3 and 32 neurons. I clicked on the button that says edit shortcut and pressed "7". Now I need to remember to press 4 when viewing 480p content and 7 when viewing 720p content...

Use a good quality dithering and NNEDI3 chroma upscaling and doubling. The higher neuron counts may give you benefits in still pictures, but if you don't zoom or your source isn't of very low resolution, just be sure to use NNEDI3 for both and don't focus that much on just the neurons. I personally would trade neurons for more features active at any time. |
