1. A method comprising:
identifying a first change in a frame generation rate at a graphics processing unit;
in response to identifying the first change in the frame generation rate, generating a first synchronization adjustment specifying an amount of adjustment to synchronize the frame generation rate with a refresh rate of a display;
in response to identifying that the first synchronization adjustment exceeds a first boundary, limiting the first synchronization adjustment to a first level; and
adjusting the refresh rate of the display based on the first synchronization adjustment.
