I've had a problem with MadVR for quite some time now (not sure when it started, maybe with upgrade to Win8) where most files have trouble playing. Most files just play the sound with a black screen, somtimes after quite a while (up to a minute) the picture appears but most of the time the audio hangs too after a while. If I try to go full screen or fast forward MPC-HC hangs.
I'm not sure it's the exact problem though because my system is much more modest and based on AMD graphics (6650M). It sounds similar enough though.... Quote:

Would recommend jumping on the bug tracker and creating a reporting an issue.
Having madshi look at a log would probably be the quickest way of resolving this.. Does changing the refresh rate do anything? Have you tried uninstalling and deleting the drivers in devicemanager and then reinstalling? make sure use separate device is unchecked. Last edited by ryrynz; 11th July 2014 at 10:29. |

FWIW, the bug tracker is for suspected bugs in madVR. dansrfe's problem sounds more like an OS/driver problem or misconfiguration to me, to be honest. These NVidia Optimus systems seem to be a bitch to get to work sometimes, it seems. Although most users seem to have it running fine. It's ridiculous that you have to rename the MPC-HC exe file to have any chance to use the NVidia GPU in the first place. None of this is madVR's fault, from what I can see. That said, I can of course look at a log. Maybe I can see something...

Likewise try changing MPC to EVR custom preset from madVR to see if that can rule out both madVR and/or LAV as being related to the issue. There is a driver bug that has existed for a long time, and you may be seeing past reports related to that as opposed to this specific issue being discussed now. I used to have that NNEDI3 driver related issue, but madshi found a work around for the driver bug. I have an Optimus system, and don't currently have any of the types of problems discussed so its not necessarily an Optimus system issue since its not occurring on all systems at this point.

I uninstalled the device driver from Device Manager and re-installed the latest beta Nvidia driver with clean installation selected. I also tried setting Auto-Zoom to 100% to prevent any Image scaling and the same black screen with audio persists.
Here is an attached log: https://www.sendspace.com/file/dij2vd. For some reason I'm still having to manually kill both MPC-HC and madVR again when I need to exit. Also, madVR is reporting that Overlay is not supported on this GPU in the OSD when Overlay mode is selected. Because of that the above log is in Windowed mode. If I attempt to FSE then madVR's OSD freezes, becomes blurred and extra large. This seems like an MPC-HC or OS/Driver level problem to me. I can manually select High-performance NVIDIA processor for any other application (including Chrome) and the selected app works as expected including any Flash/HTML5 players. However the fact that madVR detected the GPU and stored the key under OpenCL when I had temporarily selected NNEDI3 under image doubling (any scale) makes me believe that MPC-HC is probably the culprit.

Two strange things in that log: (1) VSync position information doesn't seem to be coming from the GPU driver. (2) For some reason the decoder doesn't seem to send more than 1 frame.
Don't know, maybe (2) is a consequence of (1) somehow, although I don't know why it would. In any case, (1) seems to be a GPU driver problem. |

FWIW, when I manually switch to Integrated Graphics in Nvidia's Control Panel for the renamed mpc-hc, madVR and MPC-HC work as expected.
However if I set it to Auto (Integrated graphics) or High-performance NVIDIA processor, MPC-HC/madVR/all other renderers freeze. The decoder only gives one frame as madshi mentioned as well. Another interesting observation, when I run madLevelsTweaker, it only lists the GPU as Intel HD Graphics 4600. I'm not even sure how to force 0-255 on the Nvidia output.

Also re-install the Intel drivers.
Have you tried any games or other Direct3D applications?

Thanks. I will play with it during the weekend. Another question - Looking back at this thread I saw debates over PCI-E version for AMD cards, but what about NVidia? Would an old PCI-E 1.1 impact performance? Or even 1.1 is fine for NVidia based cards? Last edited by dbezerra; 11th July 2014 at 17:44. |

I haven't tried any games or Direct3D applications yet. Is there a test application I can run that would determine if the everything is working as expected on the driver side? Last edited by dansrfe; 11th July 2014 at 18:22. |

this issue has something to do how AMD handle d3d <-> opencl (for nnedi/error diffusion) data transfer |

Do you have all the available Windows critical updates (detected by Windows Update) installed? Are you using 64-bit Windows, or 32-bit Windows? Since madshi pointed out v-sync issues based on the log it may be worth experimenting with those settings in Nvidia control panel. The default should be "Use global settings (Use the 3D application to settings)". First try it with that configured to off for the mpc file under program settings. If that doesn't work try forcing it as on (even though mpc/madVR usually doesn't listen to Nvidia's instructions for v-sync). Also check your Intel V-sync setting(s). On my system its listed under Intel HD Control Panel -> 3d, and Vertical Sync is set to driver settings (but you can try with application settings selected and see if that makes a difference).

I think discussion about dansrfe's problem should be moved to another thread - unless there are indications that it's really a madVR specific problem, which currently doesn't seem to be the case, as far as I can see.
This thread should not be used for general PC support problems. |

AMD Driver update:
With Windows 8.1 and an R9 270X, Catalyst 13.12 is still the best driver to use to get the most out of your GPU. I again had to roll-back from the latest RC driver since it couldn't handle the profiles I use to maximize performance. Just an FYI for those interested in trying the latest RC drivers from AMD QB

Just to clarify,
Blu-Ray is encoded and stored on the disc as Ycbcr 4:2:0, then madVR converts YCbCr to RGB and does all the processing and output in RGB, correct? I have read on AVSForums that most TVs convert incoming RGB signal back to YCbCr for processing unless we choose a special option to tell the TV to skip the conversion and output pure RGB. On a Panasonic this option called "1080 Pixel Direct". An easy indicator would be if the Color/Saturation slider is still working if we feed RGB signal into the TV, then the TV converts incoming RGB to YCbCr for processing and back again to RGB for the panel. So basically we get another conversion step which may (or may not) degrade the signal. What I want to say is: People who use HDMI to connect madVR to your TV, make sure you use the "PC/RGB/Pixel Direct" mode on the TV for one less conversion step.

In my Optimus enabled laptop with GT650m graphics, I can use NNEDI3 upscaling (with no frame drops for SD videos) by adding a registry key to force NVIDIA gpu for OpenCL processing; but I am not able to use any of the error diffusion algorithms due to frames getting dropped when they are enabled. I was wondering if this was due to intel igpu being used for directcompute processing. If this is a possibility, can a registry key be added similarly to force the NVIDIA gpu for directcompute processing?
