Howdy!
The game will try to run with the highest performance it can based off system power settings and game settings. I do recommend enabling Vsync under Graphic Options as a first step to limit FPS which will limit the workload. Double check Graphic Settings are lowered and resolution Scale is not set beyond 100. You may also try switching to Windowed mode and playing in a lower resolution. We provide more steps to help avoid overheating Here.
If you notice any odd behavior while at the Menu/Lobby make sure to Bug Report this to our QA and Developers. If you would like to see features added to the game’s settings you can provide this feedback in the survey and on our General forums.
