How to unlock this one?

Why are all the scripts I make so laggy?

How do I extract them?

help i'm new and really stupid

I can run battlefield 1 at a constant 60 fps, but this game stutters worse than any other I have ever seen. I get stutter every 3 or 4 seconds which causes a complete freezing of the game and cursor (both mouse and controller) for about half a second. This is a horrendous defect for what looks like a good game....
