All games use mailbox/triple buffering. Except when you enable sync to host refresh, in which case FIFO/double buffering is used. This means vsync enabled will ever tear, but at the same time, never drop to 30fps on a missed frame due to frame rate differences. To have the "best of both worlds", you should enable vsync and sync to host refresh. Previously, this resulted in additional input lag, since the host vsync would drive the EE frame timing. Now, this behaviour is disabled by default, unless you enable "Use Host VSync Timing".
