Debugging option to display fps and properties during game

there’s a debugging option to display fps and properties during game ?

For the editor, there is an easily accessible option in the View Widget.

For a built game, you can build this rather easily yourself using Time.DrawFPS. For more info about the performance, check out the profiler tools

Also, there is a simple Debug UI actor in Flax Samples that uses a simple script to show the GPU/CPU draw and update time together with FPS counter. Feel free to use it.
