Hardware-Accelerated Graphics (Compact 2013)
Hardware acceleration for XAML for Windows Embedded caches rendered UI elements in graphics memory, consuming more memory but resulting in better graphics performance.
In XAML for Windows Embedded, you can support hardware-accelerated graphics so that UI elements are displayed more efficiently, and improve a user’s experience with the UI. Hardware-accelerated UI elements require more memory to render on the display screen.
You can decide to support hardware-accelerated graphics either with DirectDraw or with OpenGL.
If you implement hardware acceleration based on OpenGL, the XAML UI that is rendered on the screen has a maximum size limitation of 2048 × 2048 pixels.
The default implementation of hardware acceleration uses GDI.
To support hardware-accelerated graphics in XAML for Windows Embedded, you must support specific hardware and drivers on your hardware board.
