Hi!
First of all, thanks for the mod!
And secondly, I built a little over 1,000 wind turbines, all small ones, and the game started lagging—not drastically, but noticeably. Also, the game speed stopped increasing, meaning the simulation simply isn't running properly. :)
But if you stop all the turbines, performance drops noticeably, even though I thought it should be the other way around. Like, when a turbine is running, something is calculated based on wind strength and so on, but if you turn it off, there shouldn't be any calculations.
That's just saying. The mod is great, but there might be a performance issue.
