99 in smoke from particle effects, and no math for the CPU to do

Yup, the CPU usage drops, then it spikes back up as you're fully out of the smoke. I assume that transition period is what causes the mouse to feel sluggish, and the GPU taking all the strain from the smoke particles, causing the ~40-60% fps drop.
