Description

Default Value

DefaultFPS

REG_DWORD

Configures the animation clock for storyboard animations in XAML for Windows Embedded.

This registry key is read when an IXRVisualHost object is created.

The value is set to 50 frames per second (fps) by default and can be reset to anywhere between 1 and 200 fps.

FPSThrottle

REG_DWORD

This value limits how often the UI can refresh during an animation in XAML for Windows Embedded.

Managing the refresh rate is useful in the following scenarios:

  • The display hardware does not support a rapid refresh rate. For example, digital ink displays can refresh only at 5 fps.
  • The battery life is considered more important than producing a smooth animation.

This registry key is read when an IXRVisualHost object is created.

The value is set to 28 fps by default and can be reset to anywhere between 5 and 100 fps.
