D3D12: using slow scratch memory!? Anyone knows what it is??
Hello there! I was testing a build of my not-so-soon-to-come game and while checking the output log I was flooded with pages and pages of "d3d12: using slow scratch memory! Allocation size: xxxxx." which if I remember correclty, was not included in logs of previous build.
Anyone knows what is the meaning of this? Do I have to worry or is it completely natural to have 12 pages of this while running the build for a few minutes?
Here is a sample of the output log: UnloadTime: 1.352414 ms
d3d12: upload buffer was too small for the requested resource! Size: 4194304. Requested: 8388608. d3d12: using slow scratch memory! Allocation size: 8388608.

I'm getting this with a shader that has 3 UAVs under D3D12 and UWP/Xbox One.
