Topic: NVIDIA Optical Flow

I have a 3070 Ti. I run the initial hardware test and this options stayed off. Should I turn on NVIDIA Optical Flow?

Re: NVIDIA Optical Flow

Well, using NVIDIA Optical Flow I'm having much more artefacts, so, I will let it turned off

Re: NVIDIA Optical Flow

I'm not understanding what really is NVIDIA Optical Flow or what benefits it would bring. I googled it but was not clear for SVP use.

NVIDIA's own GPU-only motion estimation algorithm producing motion vectors field for a given two images

move the most CPU-consuming part of me/mc algorithm to GPU

I'm having much more artefacts using Optical Flow. Is this normal?

Example of the artefacts that I have only with optical flow on

Yep. High res and integer multiplier will reduce them

This was on a 4k movie. I don't think I will find a movie with a higher resolution. And I'm showing here about a possible bug on NVIDIA Optical Flow, or maybe a possible improvement on the future.
