I got the Factorio demo expecting it to run perfectly fine on my PC
(16GB DDR3, i7 4770k, 2x GTX970) but the game hovers around 52 fps. Turning on Vsync actually improved performance for some reason however I'm pretty convinced that the problem is my CPU. I know the game only runs with one core but the CPU usage in task manager shows 1,4%, which is far lower than other games that only use one core. Does anyone else have/did have this issue?
