Lord of the Rings ROTK - King of the Dead - Falling Rocks

Hi all - not sure who needs to hear this, but for those playing ROTK and stuck on the mission where the rocks fall on the bridge, try setting the EE underclock to Mild or Moderate and that should eliminate your character randomly slowing down. I died 50 times before realizing it wasn't me so hopefully this saves someone some time. Surprisingly no guidance on this at all lol
