I believe a Windows 8.1 Update destroyed Direct2D performance.
As I have an ATI card, it's clear it's not related to specific display drivers or even to the brand of graphics card.
I do Passmark benchmarking regularly - I have for years - in order to spot problems or trends, so I can pinpoint exactly when this slowdown happened. Note the screen grab below.
The only place it gets a little odd for me: After a Windows Update in Mid February, performance of the Direct 2D benchmark seem to mostly return, but then it went back to dismal levels after the very next update.
