DEVICE_LOCAL 仅GPU可见 好比framebuffer 或者上传一次以后一直是gpu用的 srv vertexbuffer indexbuffer

 HOST_VISIBLE CPU可见

DEVICE_LOCAL+ HOST_VISIBLE CPU可见 好比constant buffer 须要每帧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
