Does your AMD card have on-board RAM for video? Or does it use a part of your system RAM? How much RAM does it have? Maybe it's running out of RAM, similar to problem karamancho seems to have? Yeah, that makes sense! @karamancho, try to decrease the GPU queue and present queue to lower values. E.g. try using 4 for both. Then check how much RAM is used. |

Usually that happens a few seconds after loading the video, then video runs smooth, then another frame drop occurs after few seconds. the odd thing is that it happens on particular video parts, usually in the part where bitrate peeks. Even if I start the video exactly from where the drop occured, it happens again. When I set the slider to a part with lower bitrate, video plays smoothly. Even with these options enabled or disabled, same thing happens again. |

madshi i am trying to respond to you on the bug tracker but its not working, i type a response, click the "add note" button and nothing happens
edit: i wonder if this is a google chrome bug, will try firefox, see if it works Last edited by truexfan81; 1st June 2013 at 07:34. |

oh madshi i have been having a weird issue lately, but i think maybe its an nvidia bug. every couple of days madvr reports "gpu/driver does not support overlays." only way to fix it is to reinstall the nvidia driver and then reinstall madvr (a reboot does not even make the error go away) this has happened with nvidia 320.14 and 320.18. so i'm tempted to revert back to 320.00 to see if the problem goes away.

HD8730M is 384 cores @ 650 MHz 128 Bit @ 1000 MHz DDR3 It should be more than enough for Lanczos3 scaling if deinterlacing job is not required. As I know, some NB vendors choose the cost-down solution to wire some particular output port(s) like LVDS / TMDS to only 1 GPU, not both via the switching IC. The usual design is always to use Intel GPU to send out all video signals while AMD/nVidia GPU is the active one. So extra framebuffer copy back from dGPU to iGPU is always required and it creates extra latency. Maybe it would work if all FLUSH settings are turned OFF? |

Do you think Jin3 would be too much for the card? As with Intel I can do Jinc3 image and Softcubic no AR 100 on chroma. Thanks Last edited by nekromantik; 1st June 2013 at 10:32. |

Hope you can look into it and lemme know if I should add it to the bug tracker or something, I've got a remuxed BD with high bitrate that would exhibit the problem you're describing but I can force software decoding with ffdshow(libavcodec) instead of LAV/CUVID and presto! all is well.....the GPU doesn't take care of the video decoding anymore so its bitrate doesn't matter, doesn't that fix the issue for you as well Last edited by leeperry; 1st June 2013 at 13:19. |

I have a HD7970 which is 950 Mhz 2048 GCN core + 384-bit DDR5-5500. Its performance should be at least 7 times as fast as HD8730M's. The estimated maximum performance for 1440x1080i content to 1920x1080p with Luma/Chroma Jinc3+AR scaling is about 120~150 fps and 60 interlaced frames' vector-adaptive deinterlacing job per second. In reality, there is no such content. Unless madshi designs some other useful features (any in-progress? ) which require more computation power than Jinc3+AR mode, the GPU with near 1000 GCN / Kepler CUDA cores, or 384 Fermi CUDA cores should be enough for real-world contents up to 4K 60 fps.

For those having problems with newer Intel GPU drivers...
It seems that Intel drivers 9.18.10.3071 (and .3111) have a bug which occurs when using the madVR option "use a separate device for presentation". You have 2 choices: Either go back to older drivers. Or disable that madVR option. FWIW, I've notified my Intel contact about this, but I've no idea how fast they'll fix this. Quote:
You could also try whether replacing "float4 c0 = tex2D(s0, tex);" with "float4 c0 = tex2D(s0, tex); saturate(c0);" makes any difference. Probably not, but maybe worth a try... |

Most web pages relating to drivers for "3rd Generation Intel Core Processors with Intel HD 4000/2500 Graphics" are error pages anyway, for me at least. Their automatic updater never does anything either.
I'm sure I managed to find the download page for the 9.18.10.3071 drivers last week via Google but I didn't save it lol.

BTW, problem is identical whether it's used before or after scaling. Last edited by leeperry; 1st June 2013 at 19:42. |
