Trying to determine FPS in a C# WPF program

Question

I'm writing an application for a touch table using WPF and C#. (And, I'm not terribly familiar with WPF. At all.) We suspect we're not getting the framerate we're "requesting" from the API so I'm trying to write my own FPS calculator. I'm aware of the math to calculate it based on the internal clock, I just don't know how to access a timer within the Windows/WPF API.

What library/commands do I need to get access to a timer?

Answer 1

I think you're looking for the StopWatch. Just initialize it and reset it with each start of your iteration. At the end of an iteration, do your calculation.
