if want to see some light at the end of the tunnel.
the NGU very high x4 scaler performed very well on my RX 480. i still don't know how people can accept such a huge regression compare to the R9 390 but not my problem. |

HD to 4k(4096x2160)
Quote:
Same scenario as mine you mean? The best I can do is NGU high for HD to 4k but for some occasions I get dropped frames with high(only a few). I am like HD to 4K--->NGU med(chroma and luma)-->Jinc AR.You? Tried NNEDI3 128(chroma and luma) to check your saying and I get dropped frames. Last edited by Damien147; 6th February 2017 at 19:45. |

there are numbers in this thread.
it was something like 3-5 times slower. my 960 out performances the rx 480 of cause only in NGU. i have a r9 270 amd and only the 960 at the time so no R9 390 or something like that but the R9 270 is fine in term of NGU performance. |

Dont use such excessive amount of neurons for chroma when youre upscaling something. Luma is the most important. Last edited by pose; 6th February 2017 at 20:34. |

"heavy" image enhancements responds quite well with NGU, it wasn't much useful with Lanczos or NNEDI3 before.
current settings: sharpen edges = 1.0 LumaSharpen = 0.75 AdaptiveSharpen = 1.0 anti-bloating filter = 75% anti-ringing filter = yes chroma upscaling = NGU (low) image upscaling = NGU (high+high) on a side note, whats "algorithm to use after doubling" for? if i don't check the 200% supersampling does it mean it remains unused? also, theres a second "Chroma NGU(low)" on the OSD, is this normal?

@madshi
I continued testing and results are mixed. On some or most sources, NGU is better than NNEDI. To be honest, the new NGU looks really good and this is the sweet spot. NGU at those settings will distort the image, but less than the other algorithms. The sharpening has one of the least ringing and added aliasing / noise so this makes most sense to be kept. I still wouldn't dismiss NNEDI entirely, someone might need it, and NGU will still add some of that GPU high pitched noise. If there is any way to make it even faster, that would be helpful, after some point it's not efficient enough and will introduce dropped frames.

edit: i think i got it, it automatically triggers depending on the source's scaling requirement. e.g. if source requires more than double it triggers the "upscaling" input, where as if the source requires less than double it triggers the "downscaling" input. then does this mean the image upscaling does 2x scaling by default? if this is the case then shouldn't "image upscaling" be renamed into "image doubling" to make an accurate description? edit2: i just noticed these doubling requirements only applies to Super-XBR, NNEDI3 and NGU.

I have no doubt it works fine for anime, although I have no anime to test with. I hope other testers will be trying it out with SD live-action movies to confirm or refute what I'm seeing. BTW, I'm using a GTX1060 with the latest drivers. EDIT: NGU still looks great for higher resolution sources, as it has since you introduced it. However, I watch a lot of SD.

Try NGU with edge blurring on 1 or 2 and ~0.5 edge sharpening and IMO it looks a bit better.. But then your performance benefit goes out the window.. Last edited by ryrynz; 7th February 2017 at 01:47. |

I don't watch anime so I'm not sure if my testing would help but why do you wanna ditch sxbr and/or NNEDI3? So far I like the latter for very low-res SD and the former in combination with SR for stuff that's too noisy to get the NGU treatment, I don't think there will ever be a one-size-fits-all doubler that will work in any given situation. I rest my case that in combination with FRC I love what SR does to motion-blur and NGU turned this combo into bloatland last time I checked =/

Maybe. Quote:
Because NNEDI3 is very slow (and relies on unstable OpenCL). If I can make an algorithm which is both faster *and* better looking than NNEDI3 with the same sources NNEDI3 shines with, then that should be a benefit for everybody. |

NGU is very good, but to me it's a pointless function atm purely because of the noise it generates on the GPU. It's EXTREMELY annoying, sounds like the PC is frying.
