Three scripts for working with FPS (Frame Rate/Second):
limiter - a script that allows you to set your own FPS limit value (30 in the game by default), which allows you to stabilize performance and avoid image twitching. The value is taken from the settings.ini file
show - a script that displays the current FPS value in the game on the screen.
monitor - script that monitors FPS deviation and beeps. For example: when FPS drops due to poor computer performance, or increases above the stabilization level (dangerous because on powerful hardware FPS can exceed 200 and leads to malfunctions and some other unpleasant consequences.)
