Frame Synchronization

Using the OpenGL

Extensions

Swap sync refers to the synchronization of buffer swaps of multiple application windows. By means of swap sync, applications running on multiple systems can synchronize the application buffer swaps between all the systems.

Swap sync requires

Proper connection and synchronization of the timing signals

A mechanism for binding several windows together so that buffer swaps can be synchronized across all windows

About Buffer Swaps

Key Points and Deﬁnitions

Buffer swaps are performed on windows.

Swap Groups

If buffer swaps must be synchronized across several windows on a single Quadro, you can deﬁne a “group” that consists of the speciﬁed windows.

Swap Barriers

If buffer swaps must be synchronized across several Quadros, you can deﬁne a “barrier” that consists of the speciﬁed Quadros.
