Anyone know a solution to make the 12bit stick for a custom 23p res using the latest 390.65 Nvidia drivers? |

Still has the same bug as described above by austinminton and invader, so for the moment I'm sticking with 382.53, which one of the later insiderbuilds shipped with.

...and if the support of Intel GPUs would be as intensive as with NVidia or AMD (which are by the way also buggy as hell, when I see the driver-numbers exchanged for working with this but not with that...) then it would be heaven... at least for machines which are meant mainly for media playback... |

I just experimented a bit with post-processing options ... and had to realize that activating the filter for compression artifacts (deblocking) is just too much for 1080p AVC on a Phenom-II X6 and 450 GT. But I saw only one core utilized. So I wonder if madVR is not even multithreaded, at least in a way that several modules would run in separate threads. Or is deblocking really such a heavy task? I believe ffdshow's implementation could handle that, even with additional random noise, but I don't have it installed anymore.

OK, you are right, I was too quick posting my question.
ProcessExplorer revealed that normal playback already takes my GPU to the limit, adding debanding doesn't matter much ... but deblocking goes beyond its capabilities, the playback stalls because the GPU gets saturated. Already using shaders for resampling is heavy, relying on DXVA2 mostly takes the GPU utilization back to just 55% (but deblocking is still utopical).

On one laptop which is showing its age all I need to do is chroma upsampling. Mainly 720p. The highest this laptop can handle is spline64 (4 tap) w/ no AR. Is this what you guys would do or would you be concerned about aliasing and ringing. I see some people use lanczos but to me spline looks better on test patterns as it’s basically just as sharp but with less ringing. Even default bicubic60 I see more aliasing/stair-stepping than in spline but obviously spline has more ringing. I’m not sure there is a consensus on chroma, or is there?

Part of it is a matter of taste; I am not a great fan of "too sharp" upscaling, and the spline kernel is more moderate than Lanczos, especially with (less/fewer?) taps.
A pity the kernel visualization page of the ResampleHQ project disappeared. I was so bold to upload a copy for the preservation of useful information. Last edited by LigH; 31st January 2018 at 01:25. |

Very cool LigH. Thanks for that. I think spline 3-tap is the sweet spot for me. I like a sharper picture but obviously want to keep the artefacts down to a minimum. Strange because you don’t hear many people talk about spline when it’s a great algorithm in a lot of ways.
Ryrynz you have to use the second link. LigH was saying the first one is dead. |

Spline 3-tap is an old favorite of many, it is simply too old to have been the sexy new thing for most so it doesn't get much publicity.
Edit: Thanks for hosting that page again LigH, I was also sad when it went offline.

so utopical is not really the case. but i was one of the old spline 3 AR user and i would still use it for "correction" scaling if it would be available not that it matters there. and scaler like jinc, NGU AA and super XBR are not much sharper or sharper at all compared to spline they have a lot less scaling artifacts and have better AA abilities. even NGU sharp is not an over sharpening scaler this can be proven by downscaling an image and upscaling it with NGU sharp and compare it to the source. |

Its your conscious chocie to use insider builds and forever suffer from it. No use needs insider builds.

Of that I am aware. I wasn't asking anyone to fix it, just making others who may be going down the same path aware of the issues. It's still broken for me in the latest builds, as well. LOL But I am fully aware this is pain I brought upon myself by putting that machine in the insider program.

@madshi - any chance you could revisit at refresh rate switching and 3D, the issue i'm always moaning about gets fixed if you disable refresh rate switching in MADVR and use KODI DS RFS instead, dont know if this is a bug or something you are aware off or whether its connected to the NVIDIA issues with 3D, worth a look though.
I much prefer MADVR switching as I also use MPC which has issues with RFS |
