			# Objective Fixes #17487 - Adds a new field `refresh_interval` to `FpsOverlayConfig` to allow the user setting a minimum time before each refresh of the FPS display ## Solution - Add `refresh_interval` to `FpsOverlayConfig` - When updating the on screen text, check a duration of `refresh_interval` has passed, if not, don't update the FPS counter ## Testing - Created a new bevy project - Included the `FpsOverlayPlugin` with the default `refresh_interval` (100 ms) - Included the `FpsOverlayPlugin` with an obnoxious `refresh_interval` (2 seconds) --- --------- Co-authored-by: Benjamin Brienen <benjamin.brienen@outlook.com> Co-authored-by: Alice Cecile <alice.i.cecile@gmail.com>
