MPDN won't start properly
Hi, I've searched around for the cause of this issue but so far I haven't seen a fix.
MPDN crashes when not using DX9 rendering mode: Quote:
Also, currently DX9 crashes upon playback. Last edited by trandoanhung1991; 18th February 2019 at 10:46. |

Personally I would say that sharpness is good as long as it doesn't come at the expense of visible/distracting artifacts - which is often a problem with previously compressed source material, as source-based artifacts result in post-scaling artifacts as well.

There's no clear consensus among users. Many like it sharp, others like it a bit softer. It can also depend on the scaling factor. E.g. at 4x going very sharp can result in cartoon like images (very sharp edges but no texture detail), while at 2x that's less of a problem. And it can depend on the content, as well. If the content is extremely soft, using an algorithm which rings a bit may not hurt at all.
Among those users who like it sharp, there are some who don't like ringing, and there are some that are ok with some ringing if it results in much sharper results. |

I compared it to the result of waifu2x, the difference is visible, and indeed your result is bit softer. I know waifu2x was intended for artwork, however for this particular image (castle), it gives surprisingly pleasant result (Noise Reduction: none, Style: photo, Upscaling: 2x).

It's definitely much better in terms of ringing now. Of course it got a bit softer, as a result, but that's the trade you probably have to make when trying to avoid ringing. On the positive side: A clean image can be post-sharpened.

Part of the problem of the original post was the downscaled image. It had a fair bit of ringing to it so in way it was preserving all the details including the ringing noise. I had to take a high res image and downscaled it myself to produce a cleaner one. The original implementation did have a bit more ringing but the perceived sharpness was largely due to ringing in the downscaled image.

did you think about using FP16 which may be accurate enough and is natively supported on new nvidia GPUs and AMD vega?
i know you wanted to test it on a 970 but if this FP16 works as advertised you should get quite a performance boost. |

Hi. I'm a new member and have been using MPDN for a while with LAV filters. Unfortunately, I can't seem to get it to work when I use the DirectX 11 presentation API. It just crashes and won't start again.
Specs: Dell Inspiron 7559 Win 10 x64 Home Edition Nvidia GTX 960M MPDN ver 2.49.0.3606 Would updating to a newer version solve said issue, or is there another workaround? Either way, where could I get the latest updated builds? I can't seem to find where the newly united team are posting builds, unless I missed something. Sorry for the rambling post and thanks everyone for your help. |

no they just made a lot of wind with FP16 for tensor and general compute for CUDA.
so much potential wasted by simply not caring for openCL. this type of code will run terrible on none turing/volta cards anyway. 27 Tflops hidden behind missing openCL support what a waste. |
