Setting it to false reverts to a DXVA 1.0 or DirectX 9 path, which is older and less efficient. The Microsoft documentation recommends using Direct3D 11 for modern Windows Store apps because it offers better integration and performance than its predecessor.

For game developers, the Windows Media Foundation (WMF) media framework is also used for handling video playback within game environments. In the , there is a WMF Media section that includes settings like "Hardware Accelerated Video Decoding (Experimental)".
