2.9.1. About VSYNC

VSYNC synchronizes the frame rate of your application with the screen display rate.

VSYNC is a useful technique because it improves image quality by removing tearing. It also prevents the application producing frames faster than the screen can display them. You can use this to save power.


Ensure you deactivate VSYNC before doing any other optimizations. If VSYNC is enabled frame rate measurements are likely to be incorrect and can lead you to applying incorrect optimizations.
