Description
So I'm not entirely sure why this warning exists:
15:04:03 [WARN] There is a memory type that is host visible, but not host coherent. It's time to upgrade our memory allocator to take advantage of this type of memory :)
but just FYI, this is generally how memory is set up in MoltenVK, atleast in version 1.1.6.
Here are some reports: https://vulkan.gpuinfo.org/displayreport.php?id=13266#memory https://vulkan.gpuinfo.org/displayreport.php?id=13265#memory
