Apps are often capped at 60fps on ProMotion displays due to render loop configuration errors with MTKView or CADisplayLink, or system-level constraints like Low Power Mode restricting frame rates.

To configure CADisplayLink for optimal frame rates, ensure your render loop correctly targets the maximum refresh rate and account for system caps that may throttle performance under thermal pressure or Low Power Mode.

Frame pacing issues and hitches are caused by render loop delays and configuration errors in MTKView or CAMetalDisplayLink, preventing frames from syncing correctly with the display refresh cadence.

Yes, system settings like Low Power Mode, thermal throttling, and accessibility configurations impose strict frame rate caps, limiting your app's maximum achievable fps regardless of ProMotion support.

The best way to diagnose 60fps bottlenecks is to inspect your render loop configuration in MTKView or CAMetalDisplayLink and verify whether system constraints or performance budget issues are limiting the display.

Yes, CAMetalDisplayLink works with ProMotion displays to achieve high refresh rates, provided it is configured correctly to avoid frame pacing problems and not limited by thermal throttling or Low Power Mode.
