DEVICE_LOCAL 僅GPU可見 好比framebuffer 或者上傳一次以後一直是gpu用的 srv vertexbuffer indexbufferant

 HOST_VISIBLE CPU可見co

DEVICE_LOCAL+ HOST_VISIBLE CPU可見 好比constant buffer 須要每幀cpu寫 gpu使用 uncached slow read writememory

HOST_VISIBLE+HOST_CACHED system memory, cached,GPU access through PCI,good resource to write by GPU ,read by CPUwatch
