TuneBrowser is supporting Direct2D 1.1 for a long time now.
However, I have not enabled Direct2D 1.1 because there is no advantage to the TuneBrowser in terms of functionality and performance, and conversely, Windows 10 users who use older drivers may experience problems (I do not intend to support both Direct 2D 1.0 and 1.1 or higher).
If you have any specific information on Direct2D 1.3 performance, could you please share it with me for future reference?
