Quick Accel

Skips the vanilla acceleration ramp so you reach normal top speed immediately instead of building up to it.

The Quick Accel module removes the wind-up from your movement. Vanilla makes you build up to your top speed over several ticks; Quick Accel skips that ramp so you're at full pace the moment you start moving. Your top speed stays vanilla — only how fast you get there changes, which makes strafing and direction changes far sharper.

Any anti-cheat that simulates movement — Intave, Grim, Matrix — will flag this at every setting above 0, because the acceleration ramp is verifiable on the server. Treat it in the same risk class as BHop: weak or unconfigured anti-cheats only. Your top speed does stay vanilla, so checks that only look at maximum speed aren't affected.

Power

How much of the remaining acceleration ramp to skip each tick, from 0.00 to 1.00 (default 0.50). 0.00 is vanilla and does nothing; 1.00 reaches full speed on the very first tick.

Lower values shrink how far off the server's prediction you land, but they never remove the gap entirely.

Disable On Sneak

Stops applying the instant acceleration while you're sneaking, so careful movement stays vanilla. On by default.

Only On Ground

Only applies the instant acceleration while you're standing on a block, never mid-air. On by default, and worth leaving on — airborne acceleration is the easiest version of this to spot.

Recommended: keep Power low and leave both Disable On Sneak and Only On Ground enabled. You get most of the responsiveness while staying off the two states anti-cheats watch hardest.
