DEVICE_LOCAL 仅GPU可见 比如framebuffer 或者上传一次之后一直是gpu用的 srv vertexbuffer indexbuffer
HOST_VISIBLE CPU可见
DEVICE_LOCAL+ HOST_VISIBLE CPU可见 比如constant buffer 需要每帧cpu写 gpu使用 uncached slow read write
HOST_VISIBLE+HOST_CACHED system memory, cached,GPU access through PCI,good resource to write by GPU ,read by CPU
