It's related to display driver. Not DirectX specific.
Many things are hardware accelerated. e.g.:
- Bitmap (GDI) operations: copy, stretch, shape drawing, etc.
- Video overlay
- 3D graphics
Disabling hardware acceleration at specific level will disable a
specific group of accelecations and forces the operations be done by the
CPU. On 3D graphics acceleration, it depend on the display driver
whether it implements CPU-only version of a function or not. If not,
that function will not be available.
