Why does a game run faster on a faster PC? Game loop and delta time explained

Frame-locked: x += 5 every frame

Delta time: x += 300 * dt

Frame rate: 60 frames per second

Frame-locked speed300 px/s

Delta-time speed300 px/s

Both squares loop across the lane. The game simulates the frame rate you choose, so the speeds you see are what a player at that frame rate would see.
