// If we have a WDDM 2.0 or later display driver, prefer the D3D11VA renderer.
//
// D3D11VA is better in this case because it can enable tearing in non-FSE
// modes when the user has V-Sync disabled. In non-FSE V-Sync cases, D3D11VA
// provides lower display latency on systems that support Independent Flip
// in windowed mode. When using D3D9, DWM will not promote us to IFlip unless
// we're full-screen (exclusive or not).
//
// We want D3D11VA in FSE multi-GPU cases due to a plethora of issues with
// D3D9Ex PresentEx()/D3DPRESENT_DONOTWAIT on hybrid graphics systems (See
// issues #235, #240, #386, and #951 on GitHub). Clearly this codepath is not
// well tested by Microsoft or GPU vendors, so stick to the more common
// D3D11-based renderer which is much more likely to behave.
//
// DXVA2 video processing is also quite buggy on AMD, Intel, and Qualcomm
// hardware with various issues documented in initializeQuirksForAdapter().
// We can avoid all this by using our own shaders in the D3D11VA renderer.
//
// NB: The reason we only do this for WDDM 2.0 and later is because older
// AMD drivers (such as those for the HD 5570) render garbage when using
// the D3D11VA renderer.
