Does WinRT provides an option to fall back to software ClearType font rendering (as Direct2D do via "Direct2D and GDI Interoperability") or we will be stuck with somewhat blurry hardware font anti-aliasing only?
回答1:
No. Windows on ARM will not support ClearType. This is by design.
Instead, Windows on ARM tablets will be required to have a high DPI.
