You draw to a DirectX surface rather than the raw frame buffer but it is by no means translated to D2D. D2D has a "GDI" emulation mode, but it's more than worthless if you care about rendering fidelity with the real thing - and you probably do if your still on GDI these days.

Ah good to know - I was under the incorrect impression that the D2D "GDI" emulation mode was the only codepath remaining. Btw any pointers on how to keep track of the graphics stack in Windows? In the past there used to be a treasure trove of blogs and content in MSDN but over time that community has frittered away. Any pointers on how to keep track of what Microsofts graphics roadmap is going forward?

The simple answer is use D2D/Dwrite for low level render code in new projects. If you use C# there’s probably higher level wrappers over these. Some of the older C# APIs wrap GDI+ which is pretty slow and renders text really poorly so go with whatever new stuff they have now.

I don’t know of any specific blogs/resources. I used to work on Excel’s render code so had a bit of an inside view.

I worked on some inhouse tools similar to Excel (rendering highly customizable grids) so efficient 2D rendering is of high interest to me. This is from C++.
