This Unity sample project shows how to use the [asynchronous GPU readback API]

to capture render outputs without blocking the main thread.

[asynchronous GPU readback API]:

    https://docs.unity3d.com/ScriptReference/Rendering.AsyncGPUReadback.html

Note that there is a trade-off between performance and latency. It's only

applicable when a small amount of latency is acceptable. Screen capture is one

of the best-fit cases for the feature.

Unity 2023 Update

-----------------

I updated this project to use the [Awaitable] class introduced in Unity 2023.1.

Now you can use the GPU readback API with the C# asynchronous programming

features (async/await).
