Framerate capped at 16 FPS
Haven't played in a while, so not sure if this popped up because of a recent update or something, but Space Engineers keep randomly capping my framerate at 16 FPS. Just today, I launched Space Engineers, and it was automatically capped. After restarting the game, it went back to my normal 120 FPS. I launched a creative world to design a ship, and it ran fine for ~30 minutes. Then it lagged, and my frames dropped and I was suddenly capped at 16 FPS again. Restarted once more, and back to normal. Went back to playing, and again, after ~30 minutes, I got a random lag spike and was capped at 16 FPS once more. Never had a problem like this before. Messing with settings doesn't seem to do anything, and it's a little annoying to have to restart constantly. The frame cap persists even into the main menu as seen in one of the screenshots. The framerate returns to 120 FPS if I move the mouse to a different program, but the instant I mouse back over to Space Engineers, it immediately returns to 16 frames.
