Unity 2019.2 Optimized Frame Pacing Notes

Optimized Frame Pacing, added in Unity 2019.2.0a6, is a feature that more precisely synchronizes CPU-computed frames with actual display output timing to reduce frame queuing delay.

Conceptually similar to VSync, it's more of a mobile-specific optimization jointly developed by Google Android and Unity.

There are platform-specific behavioral differences — it may not apply identically on iOS, and legacy devices may continue using the traditional approach.
