Single player paused CPU usage

[bjthinks]

This one is a big problem for me, since I like to pause the game and do other things while I think about my factory. When I pause with either Shift-Space or ESC, the CPU usage is about 20%. This heats up my laptop and drains the battery, so I end up saving and quitting whenever I want to take even a short break from the game.

Any chance we could get the CPU usage to go to zero when a single player game is paused? Please?

Thanks for the report however that's not a bug. You're running a graphics and CPU intensive game - it's going to use your computers resources.

Minimize the game instead of letting it run behind other windows; that will stop rendering.

Similar issue here: Game is paused, top shows CPU usage varying between 74% and 80%. After minimizing the game, CPU usage goes down into the range of 18% to 24%. Now, I have 4 virtual desktops (VD), Factorio is running on VD1, and I've the forum open in Firefox on VD2. After switching to VD2 and back to VD1, top shows again CPU loads between 74% and 80% although the game still is paused and minimized. It will remain in this range until I unminimize (or switch to) the game and minimize it again. Would that still be expected behavior?

By the way: I use Debian/sid with the MATE desktop environment. For information on my hardware, here is the start of factorio-current.log:
