I was learning about RunService. But when I read about RunService.RenderStepped, Stepped, Heartbeat's description, it says they all fire every approximately 1/60th of a second. If they all fire at that time and rate, what's the difference between them all?
The RenderStepped event fires right before a new frame is drawn, and can only be used on the client. It's usefull for things like UI or Camera movement.
Heartbeat fires before every physics update and Stepped fires after the physics update.
All these events usualy fire around 60 times per second, but it could get decreased if your server is heavily loaded. (Or if your pc is a potato, for RenderStepped, that is.)
