Hope it's not only for latest Win10 release and/or D3D12.
These functions require Windows 10, however it does not require D3D12 to be used.

How can I improve seek times? With EVR seeking is completely instant - when I press Left / Right Arrow it seeks instantly and plays instantly, almost as if there was no seek, but with madVR it takes up to a few seconds to start playing after seek - audio plays but video is frozen on a frame before seek.

Reducing queue sizes (especially "frames to present in advance") should have a positive effect on seek responsiveness. Don't set them too low though, otherwise you might increase the likelihood of frame drops.

Hi!

You could check whether the "delay playback start after seeking too" or it's parent is unchecked in the general settings section. Otherwise you'll certainly get slower seek times.

Tried setting CPU, GPU, and Present queues to minimum but it had only minimal effect.

It's not turned on, but turning it on when queues are set to minimal actually makes it work better than without delay.
To be honest, it's better even with maxed out queues.


Edit:
I just tried madVR 0.90 and it doesn't have this issue with same settings. Actually, it's nearly as fast as EVR.

I just had this issue, took me a couple days to resolve, the problem was related to windows creator update. It left the install files and recovery files on my hdd. Limiting my remaining hdd space down to 20gb. I ran disk cleanup and removed all the recovery files/ install files and junk. Once done madvr went back to normal performance. The strange part was no other programs seemed to be affected.

Make your queue sizes 8 for gpu and 12 for cpu and leave them there. I normally set my my 'frames to present in advance' at 8.

Have you tried resetting to defaults via the batch file? Might want to back up first..

Just tried this. All issues have disappeared so I did some poking. This problem seems to arise only when I'm using NGU. Even when I set NNEDI3 to 256 neurons (100 ms frame time) it still seeks faster than NGU (30 ms).
Also, this seems to occur only when video is playing. If I pause and start seeking it's instant.

Maybe itīs a better strategy to spend more time watching videos than seeking something within them I donīt quite understand why here and there often comes up the topic of perfect performant seeking. What the heck is permanently to be sought in videos? Start a movie, lean back and enjoy

If I have Chroma Upscaling set to NGU - AA Very High Q + SuperRes, then should I also enable Anti-Ringing for Upscaling Refinement for the best quality with SuperRes? Linear Light too?

I noticed Chroma Upscaling with NGU AA Very High Q + SuperRes does not allow Anti-Ringing, so it got me confused...

I thought that the consensus was SuperRes and NGU was less than ideal

Nvidia's private API for HDR will no longer work with the Creator's Update and has been abandoned according to Nvidia Rep in their forums. The Fall Creator's Update will better support HDR.

Good for you for understanding every mumbled sentence, and never being disturbed while watching a movie, and for always having the time to watch all arbitrarily long videos for the bit of stuff you're interested in partway through it.

Why don't we just use a single keyframe and then only encode reference frames?

I keep telling you to decide these things for yourself.

I watch movies in my home cinema and like the name of this institution suggests I use it like a cinema: The movie is started and then the audience watches the movie till the end. Maybe the movie will get paused when going to the restroom or when getting some beer etc (most of the time not by me, I donīt like interruptions). But seeking is indeed never really needed in my case.
Of course I understand that needs are different. But I think that seek performance is a) not highest priority in a playback chain (video quality e.g. is way more important in my opinion) and b) the given seek performance should be sufficient for everybody. When not having the time to wait 1 sec maybe itīs time to think about stress syndromes

It's really annoying if you seek a lot. eg: when you skim a movie that you already watched.

I myself seek a lot because I often loose focus, or just don't understand what they say in english.

So I have 1080p blu-ray rips and a 1080 Ti, I'm settled on NGU, but unsure which NGU to use, very high "sharp" feels way to aliased.

I'm also unsure if I should activate "debanding" since it kinda just seems to add a filter.

Sounds to me like you should turn your screen sharpness down.

What I don't understand is people who waste time criticizing the viewing priorities of others, even going so far as to suggest psychological issues, instead of spending their free time watching films in their pretense-laden 'home cinemas'.
