The 3090 is not faster/sometimes a bit slower than my previous Radeon VII. I had a similar problem when trying to speed up NeatVideo with two Radeon VII - seeing no gain (even when using a special NeatVideo beta version specifically made for multi GPU use - big thanks to ABsoft).

The support team at ABsoft/NeatVideo are really friendly and did a fantastic job in pinning down the problem: The data is sent from the CPU to the GPU with about 13 GB/s, but the return path is only about 7 GB/s on my system - which is way to slow!

I'm using a Threadripper 2920X CPU on a Gigabyte Designare EX mainboard and as the PCIE-controller is inside the Threadripper, the problem is most likely the CPU. But is it only my CPU, is it only the 2920X or is it every Threadripper?

I need your HELP:

Everybody who has a Threadripper (1000- and 2000-series) and is willing to run a small benchmark tool (all in all takes less than 5 min.), please send me a PM. Any graphicscard (even old ones with DDR5 VRAM) will do, as long as its in the PCIE 16x slot.

So, lets see if I just got unlucky with my Threadripper, or if AMD has intensionally crippled there flagship CPUs.

Conservative amount of denoise to avoid plastic look and keep image texture after denoise.

Camera settings:

Standard
Sharpness +1 (also works for sharpness 0)
Noise reduction -5

Two versions:

Without shadow/highlight curves
With shadow/highlight curves, S+3/H-3 (the maximum amount before image gets ugly) (can be used also for S+2/H-2)

Download in posts below:

Two options for 4k denoise:

1 - use noise reduction "-5" in camera and use neatvideo in post production for a better quality denoise.

2 - use noise reduction "0" in camera and avoid neatvideo in post-production for a faster workflow.

Which one to choose?

GH3 profiles - http://www.personal-view.com/talks/discussion/1003/gh2-neat-video-noise-profiles

Does anyone have a preset or know of an ideal setting to deal with footage screwed by the GH2 ISO noise-bug?

I just finished editing a project I filmed before I knew of the extent of the bug and have a lot of affected scenes shot at ISO 640.

I am not partial to NeatVideo so any other software/techniques ( @shian perhaps in CG? ) would be appreciated. Let me be clear that I already have my footage and reshooting is NOT an option.
