What are the minimum specs for a PC to smoothly run 720pp-1080p films with madVR and the following settings without frame drops:
1 - Jinc3tap chroma upscaling + Jin3tap (A) image upscaling (no doubling/quadrupling) + Catmull-Rom (AA) image downscaling + ordered dithering + mild to moderate artifact removal + (possibly) smooth motion??? 2. NNEDI3 32neuron chroma upscaling, NNEDI3 32neuron luma doubling, Jin3Tap (A) image upscaling + Catmull-Rom image downscaling (AA) + OpenCL Error Diffusion + mild to moderate artifact removal + (possibly) smooth motion??? I work at a PC repair shop and some people are interested in HT computers that can provide a good picture quality at a relatively low cost. The 2 sets of settings are for high quality and very high quality image, but I have no clue what kind of minimum specs are needed for either #1 or #2. I have 3770K @ 4.8Ghz and GTX 780 Ti, but that is FAR from minimal AFAIK. Anyone have an approximation? |

Several people have reported compatibility problems with Nvidia Optimus systems and the latest version of madVR. It is most likely some driver issue.
Does anyone here have an Optimus system that does work? If so, which Nvidia GPU and which driver do you use? A Nvidia GT 610 is a very weak card. I isn't powerful enough to run madVR with settings high enough to make it worthwhile.

For the record I have a GTX 680M (as listed in my signature), and don't have the problem. I don't believe its right to blame optimus for the problem when there is no proof that "optimus" is the cause of the problem as opposed to something with VMR/DirectX. The Nvidia drivers likely aren't the problem as us 600 series users are running the same model drivers as the 800 series people.

So it's been a while since I used madVR and I've been experimenting with the newer settings and changes over the past couple of days.
I've been having an issue where MPC-BE is more often than not freezing when leaving FSE and the only way I can seem to fix it is disabling 'present several frames in advance' which also disables DXVA acceleration. In doing this, I've noticed that my PC draws about 80w less power using the same madVR settings which I'm naturally quite happy with as it easily tops 200w when using NNEDI3 at 32/64 neurons in combination with Jinc. It probably shouldn't be surprising as my GPU is a power hungry Radeon 290 and CPU is a still pretty efficient and beefy i7 3770k. But I just wanted to make sure there's no actual quality difference between using DXVA2 and software for rendering? Nor any quality impact by disabling 'present several frames in advance' in madVR? Thanks. |

software has can better deal with error in the stream but there is no difference in BD playback. i think you got so high power consumption thx to dxva. dxva forces your gpu in at least mid powerstate and if you are not using nnedi for chroma this is not needed for 1080p on 1080p. so software takes a lot less power then dxva with high performance cards. |

I don't use AR for downscaling because there is a bug with madVR that causes aliased text with NNEDI3. http://forum.doom9.org/showthread.php?t=170769 Last edited by StinDaWg; 30th August 2014 at 15:53. |

If you're getting decent render times with those disabled, and you aren't seeing any dropped frames or presentation glitches then you might as well leave them both disabled.

That is an issue caused by using NNEDI3 doubling for luma but not for chroma which causes chroma misalignment artifacts which are then exaggerated by AR and/or LL downscaling with the sharper downscaling options. Use chroma doubling too and they go away completely. Catmul-Rom+AR+LL is good because it has the lest artifacts and you get the benefits of LL downscaling. Edit: Chroma misalignment probably isn't the right way to describe it, if the luma is sharper than the chroma that means the chroma has been blurred more so it bleeds further into the surrounding pixels but it is still perfectly aligned with the luma.

Well, I figured out why I was getting the large power usage discrepancy between using DXVA and software - NNEDI3 wasn't working without DXVA. I did think that using 64 neurons for chroma upscaling and luma doubling was coming a bit too cheaply, actually Render times and power draw were the same with any NNEDI3 settings enabled or disabled.
So went back to DXVA2 and the image quality increase was immediately apparent using NNEDI3, as was the power draw and render time differences. Using the latest dev build of MPC-BE seems to have fixed the leaving FSE mode freezing from my brief testing last night too so fingers crossed. On another note, I updated to the latest catalyst 14.8 WHQL drivers yesterday and power draw, heat and noise went up considerably on my R9 290. PC was pulling 250w using the same settings that only required about 180w on the 14.4 drivers! Think I'm gonna revert right back to 13.12 though as I've read further back through this thread that most folk still recommend 13.12 as the most efficient for madVR. |

Well, I have tried every driver since 13.12 and each time there has been a performance hit and I rolled back. I push my 270x to the max, so it's very easy to see this hit in performance, since I will immediately get dropped frames. I know every system is different, therefore it's always best to test for yourself, I'm just sharing my experience

I've discovered that my TV (Sony 55W905) can only display 4:4:4 chroma in Game or Graphics modes but only properly displays 24fps input without judder in Cinema mode. So I need to make a choice between the two unfortunately.
Am I correct in thinking that if I sacrifice 4:4:4 chroma there's no point in using NNEDI3 for chroma upscaling with madVR as it'll just be blurred by the TV anyway? |
