I "definatley" prefer using SuperRes..i was just trying to understand WHY you are not supposed to use it with NGU .
I think there may be some benefits from superres with chroma. It's unclear.
In graphics card talk, superres is the process of rendering the image at a resolution higher than the display resolution then downscaling it back down to the display res. If the chain goes NGU --> Superres, I guess it wouldn't really hurt much. If the chain is superres-->NGU (which I think it is not) that would destroy NGU's ability to do anything.
But if the original res is a perfect multiple of the display res (1080p to 2160p for example), then NGU does the job entirely with its doubling. If the original res is something like 720p, then a doubling puts you to 1440p, 1440p is not half of 2160p so depending on your setting, another option is used. I use double and double again so I think it goes 720p-->1440p-->2880p-->2160p but I could be wrong. In any event, once NGU gets you to 2160p, I don't think there's any benefit of superres to 2x or 4x then downscaling the video. There *might* be some benefit if your chain is NGU 720-->1440 SOMETHING ELSE 1440->2160.
If you prefer the look with superres, by all means go for it. For me, I did not like the look better.
I think madshi has indicated that superres with NGU is a waste of GPU cycles. I didn't see anything about superres hurting just not doing anything. This is a quote from madshi on superres with NGU:
As far as I can see, NGU produces results which are so good that SuperRes doesn't know how to further improve them. So using SuperRes with NGU simply doesn't bring any benefit. It may even harm image quality. It's better (for image quality and speed!) to use NGU on its own, without SuperRes.
I've said it many times now: NGU does not benefit from SuperRes, results can actually get somewhat worse when switching SuperRes on with NGU. So use NGU alone, without SuperRes.
If you want to compare NGU to NNEDI3, turn off SuperRes for both. Then, with a reasonably sharp source, NGU produces much sharper results. If you enable SuperRes that changes the whole situation.
Here is one discussing using superres on the on the last non doubling step:
Since NGU doesn't benefit from SuperRes, is possible/useful to apply SuperRes only to the last upscale step (Jinc/C-R etc.), after NGU?
Answer from madshi:
Might make sense right now, but probably won't make sense in the future, because in the future NGU will probably be able to directly upscale by 3x or even 4x. So there might not be a "last upscale step", anymore, but when using NGU, the last step might always be a downscaling step instead.
NGU can do 4x now (I dont remember if 3x ever got implemented). Double and double again or direct quadruple followed by a downscale should be better than superres I'd think.
