Image doubling cannot be used at the same time as DXVA2 scaling. Does chroma upscaling as well so this option overrides chroma upscaling. May require a restart of madVR to take effect.
Just to say that my laptop with Intel HD4000 graphics can use madVR default scaling settings even with smooth motion enabled. DXVA2 scaling also enables Intel's video enhancements (enabled by default, at least on my laptop) which include aggressive sharpening and dynamic contrast which produces terrible banding in some situations.
