I would use air grates to maximize the efficiency of the heat sinks, but there are this green lines everywhere, which creates tonnes of lag. How can I fix this ?

By the way: you do a great job.

The green lines indicate the range of the air grate, and shouldn't be causing any lag (it's just a few OpenGL line draw calls, which is very cheap). However, they can be quite annoying (they appear whenever the pressure of the tube changes), so I think I will probably change it so they're only shown when the air grate is right-clicked (or sneak-right-clicked when upgraded; right-click will show the entity filter GUI in that case).

ok thanks !

Leaving open until 0.11.4 release (will be in next day or two)
