--- Quote from: tkolsto on October 23, 2022, 02:52:03 pm ---P.S, chroma scaling should be set to NGU if you can afford the processing

What is so good by choosing ngu? what are the benefits and er are several ngus. I have read about it on doom9 but dont fully understands this. Is there some short answer. I get that one shouldnt use this simontaniously with super res.

from doom9: NGU Family: {variable super slow} [medium] madshi's own Next Generation Upscaling. A sharp doubling algorithm with minimal artifacts. NGU Soft, Standard, and Sharp can also quadruple the luma in one step. The Anti-Alias version is softer but reduces aliasing and is more tolerant of source artifacts. Works in Windows XP.


what is doubling? or just is there simple way of explaining what is good about this ngu setting and what is most like the best setting between standard soft and sharp or anti alias.

when I have chose pixel shader in madvr hdr setting and also set chroma upscaling to ngu default setting which is anti aliasing low, I get a rendeing time between 15 and 21 milliseconds. Is that good enough or recommended or should milliseconds be desireable to a lower value like let say approx 10 milliseconds.

NGU is for me, the best scaling algorithm I've seen implemented in real-time, well.... It's the most consistent with a wide variety of content and produces superior results to the other scalers in MadVR and frankly, still bests the stuff I've been messing around with in MPV (occasionally, I can get better results but its content dependent). There are better scaling algorithms out there but performance / consistency isn't there yet. Now that GPU prices aren't ridiculous, I will definitely be playing with things more. I've had some success messing around with massively threading 'offline' scaling algorithms, that might prove interesting in the future.

Doubling is another 'step' where the image is upscaled larger than it should be and then downscaled again (using whatever downscale filter you use, I use ssim) . This can lead to a better final image.

I've done some testing. It's strange. I used latest nvidia drivers 522.25 - it's only software change since installing RTX 3080 (for test I also switch back to 471.11 - from June 2021 - same thing). When I play in madvr with D3D11 or exclusive mode then I get jerky playback (but info Ctrl+J says everything is fine, no drops or repeated frames). When I switch to madvr overlay everything is back to normal - smooth playback. With JRVR it's fine too. In my opinion quality of madvr overlay is similar to JRVR. But I think D3D11 have slight advantage - better colors and "3d like". Or maybe it's only autosuggestion :)

So problem is with madvr (with my RTX 3080 LHR card) not MC. I want to switch to JRVR but I can't properly set HDR to SDR conversion - I put 50, 200, or 500 in target nit but always get that same dark picture (changing value not change output brightness, shadows are crushed). With madvr everything is fine with 200.

So for now I'll stay with madvr overlay.
