As graphics hardware evolved, GDI gained the ability to be hardware-accelerated through a set of DDIs ( Device Driver Interface).

Many video cards came to implement these DDIs, and it became commonplace to buy a video card to improve your Windows performance.

很多视频卡实现了这些DDI，而通过购买一块视频卡来改善你的Windows性能亦成为平常之事。
