Otherwise on unmap you can get the validation layer error: "ID3D12Resource3::ID3D12Resource::Unmap: pWrittenRange does not point to an empty D3D12_RANGE and the heap type is D3D12_HEAP_TYPE_READBACK. Readback resources can be written by the CPU but there's not much utility. The rationale is that readback heaps are stuck in COPY_DEST state such that the GPU can never use what the CPU is writing. The range [0, 524288) should be empty (Begin >= End)." Check also https://learn.microsoft.com/en-us/windows/win32/api/d3d12/nf-d3d12-id3d12resource-unmap "This indicates the region the CPU might have modified" -> tracy essentially declares the entire range as written, but it's not even a cpu->gpu write buffer -> bug.
