What climate crisis? I have never noticed one it´s hot in summer and cold and snowy in winter just like the previous 39 years.
And every game just pauses the scene when it get´s paused while the computer is still rendering that scene.
To stop overheating the graphics card by the sim there is a trick: You must set it to windowed mode with ALT + Enter, and minimize it afterwards to have it down in the taskbar.
I always use this trick when making new textures in Photoshop but have Flight Sim 20 running at the same time to have more CPU performance in Photoshop and check the textures after every change in the hangar
