Coal Clamps - Performance Issues

[Yourgrandmother]

So recently I have converted my beautiful town into a filthy dirty Coaltopia. Hundreds of coal clamps built, some areas densely concentrated with 50+ within viewing range. I have noticed that the smoke has greatly impacted the game performance. I am approaching slide-show levels and before people comment on 'get a better computer' even my friends with high-end machines are getting FPS drops of 80 to 20 in these areas. When they mature performance goes to normal but this is yet another problem like the falling maple leaf wall that will make town virtually un-raidable unless you are on a super computer.

Thanks.
