Canon Raw Light Real Time Playback - System Requirements?

I can't playback Canon Raw files from a C200 even at 1/16th resolution in Premiere.

Playback is just fine in the Canon Raw Development tool.

I have tried the following builds

Build 1:

CPU: Threadripper 1950X

GPU: 1080ti

RAM: 128Gb

Storage and Cache: m.2 drives

Build 2:

CPU: i7 7700K

GPU: 2080ti

Ram: 64gb

Storage and Cache: m.2 drives

It does, however, playback just fine on my late 2013 iMac in FCPX... Premiere still won't play it back.

It doesn't appear to be using the GPU either... is the Canon Raw Light only a CPU Debayer?

Does anyone have a system that can play it back? What are your specs?

I'd love to see a thread of working systems.

Update (12/11/18):

With the new CC 13.0.2, 1/4 res playback possible (a couple of occasional hiccups) on:

Build 2

CPU: i7 7700K

GPU: 2080ti

Ram: 64gb

Storage and Cache: m.2 drives

The Thread ripper build is in production, and I will test when I am able to update.

Still no GPU usage.

Update (1/17/19):

CC 13.0.2, Choppy Playback in all resolutions.... except after repeatedly playing a clip, 7 or 8x, it will playback in full resolution. This only functions for one clip at a time. 9% GPU usage. 100% CPU usage, 40GB of RAM usage!!! The test project is 3 clips totaling 1 minute of footage.

Moved the 2080ti into the Threadripper build just to ensure it was as good as I could get it with available components...

Build 1a

CPU: Threadripper 1950x

GPU: 2080ti

Ram: 128gb

Storage and Cache: m.2 drives

Premiere uses more and more RAM every time I import and try to play a new clip. It feels like an after effects RAM preview...that then isn't cached to a drive... Anybody out there that could help me?
