In the classic theme Windows 7, 2D acceleration there are no problems:
- with any discrete Nvidia graphics card
- with any integrated Intel graphics
- with old AMD cards, for example HD4670 + Catalyst v 13.9
Low 2D performance is available on new AMD video cards only!!!
For example, the old HD4670 (2008 release) in the 2D mode has 10 times higher performance than the R7 360 (2016 release).
Ha-ha-ha!!!
