GPU Preview cache option grayed out

[hctitoto]

On the "New Project" Screen, on the "Video Rendering and Playback" section there is a new option right under the Renderer: Mercury Playback Engine GPU Acceleration (CUDA). It says "Preview Cache" And it is set to "None" and it is grayed out and can't be changed. If you hove over it, it says: "Uses persistent Caching on the GPU memory for increased performance". Does anybody know how that works and why it would be grayed out if I have CUDA? is it a future feature for the new nvidia gpus only? or for AMD cards only?

Here is my system specs:

x2 GTX 1070 (Latest Driver 391.35)

i7 8700k

32GB RAM

Premiere Pro CC 2018 April release (Version 12.1.0 Build 186)

I think this option is for the new AMD Radeon Pro SSG Graphics: AMD Fuels Pro Video Powerhouse: Accelerated REDCODE RAW 8K Workflows for Adobe Premiere Pro CC with ...

I came at this post since I got horrible results with realtime. Was looking for a sollution but I do not hope this means nvidea people (got titan xp) have to accept slow results. It feels adobe software utilizing the gpu needs some attention.

Though I have a  Radeon Pro 580 8 GB and it's still greyed out!?

How to switch off this very super new AMD Radeon caching and decrease my work? I want to use disk caching for playback preview.
