I've been searching for weeks now what Pump I0 in the statistics bar means??? Although I have a lot of spare time for scripts, physics, etc, my sim FPS is always between 38 and 42. The only difference I see with other sims is the number behind "PUMP I0" (or Pump IO ?). This is always around 10 ms. On all the sims I've checked this is always less than 1. I have no clue what it means and cannot find it on any help page. A big thanks for a short explanation!!!
