Gets or sets a value that indicates whether to display the current frame rate.
Assembly: System.Windows (in System.Windows.dll)
The property is useful as a diagnostic while you are optimizing your application code by showing the frames-per-second (fps) of the current UI. You can use the frame rate information to identify performance bottlenecks in your application.
You can set this property only at run time. Only set the property while debugging, and remove it from production code.
The format of the frame rate counter is as follows:
currentFramerate is the optimal frame rate that would apply in absence of an upper frame rate limit, based on conditions of device. You can specify the maxFramerate value by setting the MaxFrameRate property. The default value is 60.
The currentFramerate and maxFramerate values are interpreted to mean that whichever number is lower is the actual displayed frame rate. You can illustrate this relationship between currentFramerate and maxFramerate by setting a deliberately low frame rate, such as 2 per second, and observing the results.
If EnableGPUAcceleration is true AND is true, an additional frame counter displays in the upper-left corner as an overlay within UI. The format of this frame rate counter is as follows:

videoMemoryUsed is in KB. intermediateSurfaces refers to surfaces implicitly created to represent the software-rendered parts of the application on the GPU.
