Description

This extension is based on VK_EXT_present_mode_fifo_latest_ready and provides equivalent functionality.

This extension adds a new present mode, VK_PRESENT_MODE_FIFO_LATEST_READY_KHR.

This tear-free present mode behaves much like VK_PRESENT_MODE_FIFO_KHR, except that each vertical blanking period dequeues consecutive present requests until the latest ready is found to update the current image.

While this seems similar in concept to VK_PRESENT_MODE_MAILBOX_KHR, the fundamental difference is that the processing of the present requests is done during vblank. From the application perspective, this means for example, that in a flip-based model, a single vblank may cause multiple swapchain images to be released at once, while VK_PRESENT_MODE_MAILBOX_KHR may continuously be releasing images as new requests become ready.

This additional present mode is useful when using a time-based present API.
