Community-made tools are often better at managing resources than the base sim.

Go ahead. Load up that heavy scenery. Turn on the live weather. Push back from the gate. And watch your frame rate soar.

It was a cold, rainy evening at Heathrow (EGLL). The Zibo 737 was parked, ready for a long-haul flight. The pilot, David, loved the realism of X-Plane 11, but today it was unbearable. His frame rate was hovering around 12-15 FPS. The cockpit was barely usable, the terminal was a blur of stutters, and VATSIM was out of the question—he couldn't handle the load. David was about to quit, feeling that his GTX 1070 and i5-8400 were too old for modern flight simulation. Chapter 2: The Whispers of the Community David turned to the X-Plane.Org Forums
