this was my first steam reactor so it will be a bit basic
The reason why its laggy is because there are so many particles in the terrain. If the reacor took up more of that space, or some of it was removed, T.P.T. would have an easier time rendering the particles and resulting in less lag. Nice power plant @nippy, you should check out mine, +1
Please add bigger buttons with wifi above the reactor because its hard to see where they are and it will make it better.
