In one of Scott Manley's videos (Interstellar Quest I think), I heard him say that he was running the physics of Kerbal Space Program at half-speed so his computer could handle it. He then doubled the speed in post-production.
How can I halve the simulation speed of Kerbal Space Program, or any other game for that matter?

What Scott Manley did was lower the delta time slider in the settings menu. This essentially slows down time in-game so that the game doesn't have to make the physics calculations as quickly, and can devote a little more time to rendering them. It will cause everything to happen more slowly, but will improve your framerate.
