Dishonored Forum  /  Pison Skip Elevator

Hello guys! I watched a couple of speedruns and got amazed by those Elevators and tried to reproduce. After a few tries I did it in the first mission Well u know, the empress thing. But when I came to the prison I simply couldn't, I always got stuck halfway. I know it's a fps fact and I only have 130 fps. Any suggestions if it is possible to do it even without having around 250 fps or at least a decent .ini?
