Tried 2.1.1 version.
Artemis model (HQ & MQ & LQ) has a bug.
When scene change occures then first frame of the next scene is not denoised. And only first one. Second frame and else are denoised. And this is for every scene.
Theia model does not have this bug.
p.s. And JPEG compression ratio is still not fixed. 53% instead of 97%!
