Describe the bug

The game drops to 20fps at times, only when the vortex tubes keep going from 99C to 100C and back rapidly due to low bar in the system, it generates lag due to the refinery being connected I believe

How to reproduce the bug

Place hot side of vortex tube on refinery, make a starter pressure system and as you barely reach refinery process temp, lag will occur

Expected behavior

FPS drops from 75+ to 20 Fps

Sounds like you haven't insulated your refinery.
