This is topic I wanted to raise already a lot of time ago. 

I have a very decent system, more than recommended specs. But as soon as you launch the game my fans go crazy, and don't stop for the whole time I'm playing the game. I'm playing on high settings.

After so many patches, maybe we could start talking about the optimization? Would you need some data like what's being put under strain? It's about GPU. Which makes not much sense at the starting menu screen or on the freshly created map with no structures yet.

The game also fills almost 90% of my 32gb ram.

Not sure if it's my personal situation or a globar trend
