d3d12: using slow scratch memory!

Hello there!

As I was trying the latest build of a project of mine I stumbled upon nearly 8000 lines in the output log informing me that d3d12 is using slow scratch memory! I do not know in what effect this influence my project but I sure would like to know.

Here is a small sample of the output log:
d3d12: using slow scratch memory! Allocation size: 8388608.

And so on for 8000 more lines.

If any of you knows if this is a problem that would be great! It would be even better if one of you could explain to me the meaning of this.

Thanks!

It is something the Xbox team is working on apparently.
DirectX 12 on Xbox One now available with Unity 2018.3

But an explanation of what it is and how it affects performance I haven’t seen
