08 Presentation

After you have submitted viable work on the GPU, you can present any number of swapchains. Please note that you need to make sure if you are presenting a swapchain, you must have submitted work on the queue that you have used when creating the swapchain.

// This does the actual *recording* of every single command stream alive.
m_lgx->CloseCommandStreams(&currentFrame.graphicsStream, 1);

// Submit work on gpu.
m_lgx->SubmitCommandStreams({.targetQueue = m_lgx->GetPrimaryQueue(CommandType::Graphics), .streams = &currentFrame.graphicsStream, .streamCount = 1, .useWait = true, .waitCount = 1, .waitSemaphores = &currentFrame.transferSemaphore, .waitValues = &currentFrame.transferSemaphoreValue});

// Present main swapchain.
m_lgx->Present({.swapchains = &m_swapchain, .swapchainCount = 1});

// Let LinaGX know we are finalizing this frame.
m_lgx->EndFrame();

Make sure you present before ending the frame, and you are good to go.
