Windows does let you disable high dpi scaling on an app by app basis (if you right click an app icon, pull up properties and go to the Compatibility tab). In Windows versions prior to 8.1 the UI wouldn't let you do this for 64-bit executables, only 32-bit ones. For 64-bit apps the checkbox to disable dpi scaling was greyed out, even though if you set the key in the registry (using the same key that the UI would set for 32-bit apps) it would work just fine for 64-bit apps too. In 8.1 they fixed this stupidity and the compatibility tab UI will work for any app regardless of being 32 ot 64 bit.
