Block Event Separator

Minecraft runs all block events of a game tick at once, so pistons that start together appear to animate in sync. The mod separates those events by their index and runs them in a fixed order, one after another, so the order in which pistons extend and retract becomes visible within a single tick. Separation happens on the server side and, on the client, block events are separated too, while the server-side behavior stays unchanged.

The mod has three modes, set with the blockeventseparator mode command, and a pace setting controlled by blockeventseparator interval, which takes a value in ticks greater than 0. Its interval slows the game down so each step through the block events can be followed. Moving blocks are also separated by index, which makes piston animations more consistent with each other. Fabric and Quilt are the two loaders that run the mod, and from Minecraft 1.16 onward it can hook into G4mespeed, where the separation mode is chosen under Server Settings and persists in G4mespeed's options across restarts.
