Once your first setup works, the next gains usually come from cleanup. Fewer leaks. Better routing. Smarter containment. More respect for what the environment is already doing. This is where the game starts rewarding judgment instead of panic.
A stronger factory rarely comes from a single trick. It shows up as tighter loops, shorter support paths, and layouts that let the environment work with you instead of against you.
Steam that leaves the working area can reduce what reaches your Dryer or Condenser. Contain the steam you rely on, instead of letting the loop lose that input early.
Checkpoint: the Dryer and Condenser keep getting the steam input your layout is designed around.
Overly long routes add travel time and jam points. Redraw each line to the shortest path that still feeds its machine, and group related systems close together.
Checkpoint: material reaches every machine over a shorter line with nothing backing up.
Terrain like lava can route or contain a flow you would otherwise build machines to move. Read what the environment already does before adding more gear to fight it.
Checkpoint: terrain holds a boundary the machines no longer need to contain.

Dryer, Condenser, and how to keep the gas in the loop instead of the air.
Evaporation, corner leaks, and building reservoirs that hold their level.
Footprints that keep support paths short and the loop contained.
The habits that stop these leaks from creeping back as the factory grows.
Most midgame gains come from stopping waste first: shorten routes, reduce leaks, and let terrain or containment solve problems before adding more machines.
Exact efficiency gains and final layouts still depend on your terrain, unlocks, and whether the line is already stable enough to optimize instead of troubleshoot.
Start by reducing leaks, shortening routes, separating mixed streams, and checking whether terrain can do part of the containment or routing work for you.
A line can work while still wasting water, steam, travel time, or tile space. Optimization begins when stability exists but hidden losses remain.
No. If the line is still unstable, treat it as a troubleshooting problem first. Optimization becomes useful after the core loop already behaves predictably.
