[Read me] The GPU load when using the SDR console is too high!?

So,

For anyone who's interested the article below compares GDI (old) with DirectX / Direct2d (latest and greatest). After reading this you'll understand why new code generally uses Direct2D or OpenGL.

So did you basically rewrite MFC to do this or just the owner draw features of the GUI?

I write my own windows controls and implement the drawing in Direct2D, examples are the waterfall, spectrum, Mode & Filter buttons, Audio display etc.

You have far better tessellation and effects in Direct2D than with GDI/GDI+.
