Matter.Events.on(runner, 'beforeUpdate', (e) => {
          Matter.Body.setVelocity(body, {
            x: -2,
            y: body.velocity.y,
          })
  })

Im setting the velocity like this. my problem is depending where i run this code it object moves in diffrent speed.

if i run it with node 16.4.0 on my local machine it moves the object super slow.

event log from my machine

{
  timestamp: 949.9999999999992,
  name: 'beforeUpdate',
  source: {
    fps: 38.873999999999995,
    correction: 1,
    deltaSampleSize: 60,

    deltaMax: 33.333333333333336,
    events: { beforeTick: [Array], beforeUpdate: [Array] }
  }
}

if i run this code as example on a heroku machine wiht node 16.4.0 it has the speed which was intended.

event log on heroku

     deltaMax: 33.333333333333336,
     events: { beforeTick: [Array], beforeUpdate: [Array] }
   }
}

is also tried with or without fixed update

  const runner = Matter.Runner.create({
    isFixed: true,
  })

what do i need to set that the move always at the same speed?
