SpletSwapChains are how Direct3D sequences rendered images for display output. You may have heard of double- or triple-buffering, V-Sync, and refresh rate. Those are all properties … SpletYes, you need to wait on that semaphore before your swap chain image will be used as a transfer destination. Also you need to wait on it because it's a binary semaphore and you need to unsignal it (wait) before you can signal it again. You don't need fences if you perform no CPU read/write operations with resources (and you have none here). memphis to austin flights allegiant
