joker97: Some versions support hi dpi some versions scale it 200% and some don't support
It seems with Windows 10 Microsoft is going through a Carbon -> Cocoa transition of its own in the form of win32 -> WinRT. Hopefully we'll see more developers embrace WinRT so end users get all the benefits that come with it such as being Hi-DPI aware, hardware accelerated GUI, more efficient both memory and CPU (which should translate into longer battery life).
