How to boost FPS on Mac

Before touching in-game settings, three things apply to every game on macOS:

• Play in full screen: macOS turns on Game Mode automatically, which gives the game priority on CPU and GPU and lowers controller and AirPods latency.
• Use MetalFX when the game offers it: it renders at a lower resolution and upscales with little visible loss.
• Close browsers and heavy apps: memory is shared with the GPU, and every free GB counts as video memory.
