Depending on the model ?  so, setting the stream to only 2 or in your case 4 using the model Realesr-general for example improves the speed for you ?

Did a quick test with 'realsr-general' and a sd source: no
But, Yes, it did help with other models. (using VSGAN, VSMLRT)
I rarely use RealESRGAN or other machine learning upscalers, since doing ml based denoising and restoration and then upscaling with nnedi3 usually gives me better results.
=> test it for yourself. Dependent on the source, the model used the other settings you might get different results.
Might be that it doesn't help with RealESRGAN at all, or even hurt.

I've guessed as much..  uhuh.. same here..

Ofcourse, i only apply upscaling to SD content.. It's doesn't make sense to me to upscale already FHD content.. even further.. in the latter case using simple sharpening techniques, and denoisers does a nice job.. imo..

Vsgan, vsmlrt..all other upscalers are bad compared to ESRgan imo.. !

But it's interesting you yield better results than ESRgan using denoising & restore followed by upscaling.. 
and by using NNEDI3 ?  ← ThAt doesn't do a thing for me...  Using the resizer at the resizer base section of hybrid yields pretty much the same results... and NNEDI3 or any other resizer (except for ESRgan).. doesn't improves that a bit ... not even a litle   !

Can you give me an example of wich filters you use in what order / queue ?
Anyway, is the filter order by default set right in hybrid ? when using denoisers, sharpening etc .. ? Anyway, i've played with that a bit, and i don't see any noticeable difference though..


I'm eager to know what the results would be using your combo on my dvd collection ..
