Just an FYI regarding the older low-end pre-GCN AMD cards (HD6570) performance. I have my primary display set at 6bit and my secondary as 8bit. Playback on the 8bit monitor with error diffusion enabled drops frames and the render queue can't keep up with all material. If I set it to 7bit, back to perfect playback with error diffusion enabled. If I turn off error diffusion and set to 8bit, same perfect playback. Not sure I can see a difference in the image with playback. Is one option more "optimal" than the other?

Performance in general is improved certainly. I can now watch that 1080i/25 video in a full screen window when using DXVA2 Native as long as I don't open any other windows on top, but not when using software decoding, so maybe CPU usage is the problem? Seems strange since this CPU is pretty beefy (mobile Ivy Bridge Core i5). If I even open GPU-Z or Task Manager it stops working and I see GPU usage at 99-100%, so I guess it's sailing close to the wind.
When the render queue dips the frame order still goes all wrong (requires pausing and resuming to fix), but this bug has existed for as long as I can remember on all of my machines.

render times are good now same or better than 86.9.
all version still freeze when fullscreen exclusive is used and active when a new/next file is loaded. tested with all 3 g versions and 87.1. this is a very typical usages and easy to reproduce but no one else reported this issue. a problem at my end? |

I'm getting framedrops with smooth motion + debanding during fade ins/outs if I disable rerendering frames for this.
Is this expected behavior? GPU is a GTX 670 at 1.2Ghz and queues seem to be fine. With smooth motion off I'm getting "just" presentation glitches in such situations. Dunno if wanted/needed, but I guess it doesn't hurt to link to a debug log: https://www.mediafire.com/?igbz9sayzry2rw7 |

madshi,

While playing content UHD (4k) began to appear such messages OSD: 1, 2. Sometimes played with artifacts in windowed mode and black screen in full screen. One time playback of many attempts was normal. Maybe to you can help debug information: madVR - log |

Antony, is this problem new with v0.87.x, or did this also occur with v0.86.11? Can you play with all the various settings a bit to check if any setting changes anything? How about default settings, does it occur with those, too? Ideally, I'd need to be able to reproduce it somehow... Quote:

Is it possible that you're running out of GPU RAM? Try lowering the GPU queues and/or the number of pre-rendered frames. Does that help? |

Thanks for the new release, just tested v0.87.1. Everything works as expected.
If you're still interested, "use OpenCL to process DXVA NV12 surfaces" works here correctly (Intel HD 4000). I'm not noticing any performance penalty from this. I really like the profiling's flexibility. I'm only missing an ability to use comments inside the script. Something like: Code:
/* comment */ I might have overdone it, but with 5 or more rules (SD/HD/FullHD + fps checks) it takes a while to sort out what is what (or what it was supposed to be). Perhaps something to consider in the future |

I found out what happens. I was installing new drivers and forgot to disable video "enchantments".
It's quite strange actually because it doesn't work if I select "dynamic contrast" and any of the "De-Blocking", "Edge-enchantment", "De-noise", "Mosquito noise reduction". At least one, no matter which... "dynamic contrast" alone works fine, same as others without "dynamic contrast". So in fact it's not a problem for me, because I always disable those options, but still maybe there is a way to fix it on madVR side. |

For what it's worth, I am really happy with how the profile switching works in the new version of madVR - I just haven't said anything as I didn't want to interrupt the Nvidia OpenCL discussion.

The oldest Windows 8.1 certified drivers are 327.23 from September. I tried installing 310.90 anyway, and it was successful - I was able to use the new error diffusion dithering. However, enabling any of the nnedi scaling options still resulted in a black screen. I understand that HTPC users don't have much reason to keep their drivers up to date, but the opposite is true for gamers - you need to stay on the latest drivers if you're playing the latest releases. It's often recommended to use the beta drivers rather than waiting for new WHQL drivers to be released. I typically avoid those however, as they often cause problems for madVR. |

When I toggle deinterlacing (Ctrl-Shift-D) while playing, the image shows / disappears. Also (maybe this information could help?): After the initial green screen, when I resize the window I get a completely white screen. Smooth motion seems to be completely unrelated. |

Off-Topic, but in C++ I use "#if 0" to disable large code blocks to avoid such problems..

@madshi the issue was introduced for me in 0.87.G I tried with the optimised file and the latest build v0.87.1. Each time I've reset the setting to default using the bat file to reset madvr settings I will play about with it again some more and try get you a log

I could interpret your post as saying that the problem did not occur in v0.86.11, but I don't want to interpret, I want to know for sure, without any doubt. So please say it clearly: Did this issue occur in v0.86.11 or not? Please double check if you're not sure. Thanks. You mean with OpenCL? Does NNEDI work for you with that driver? Or just error diffusion? Quote:
Ok, I'll look into it. |

It is not a regression actually. I've tested few madVR version back and the same results. So either I never noticed this (not likely) or AMD break something in drivers. Anyway sorry for interrupting regression hunt
