Looking at the forums, the game runs perfectly fine but if you watch your temps whilst playing they will run the cpu and gpu at 100%
This doesn't happen for everyone though, just going off what I've noticed myself on my system and what others have said from the steam forums. VSync and locking the FPS to 60fps has sorted my issues. The issue seems to be that its not very taxing on newer cards so the cards will run the game at the max it can so the cards hit 100% and high temps as nothing stops it from rendering what you don't essentially need.
