Examples described herein generally relate to rendering graphics using a graphics processing unit (GPU) in a computing device. A synchronization object associated with a wait event can be created, wherein the wait event indicates a time offset before a timed event associated with a display device of the computing device. A plurality of rendering instructions for the GPU can be stored in a buffer, wherein the plurality of rendering instructions can be received from an application before a release of the synchronization object. Release of the synchronization object can be detected based on occurrence of the wait event, and the plurality of rendering instructions can be sent from the buffer to at least a portion of the GPU based on detecting the release of the synchronization object.
