The original Asteroids game is now available for D3D12 enabled graphics cards. An updated version of the D3D11 Asteroids game is also available. The new versions require Microsoft Visual C++ 2017 Redistributable (x64) to be installed (it is linked on the downloads page).

For those interested in learning about D3D12 programming, I would recommend checking out:

The braynzarsoft tutorial link really helped me understand the purpose of all the D3D12 pieces as well as understand step-by-step how to put everything together. I also found Alex Tardiff's blog posts about transitioning from D3D11 to D3D12 very informative and they motivated me to make the transition as well (by the way, Alex has some really good resources at the bottom of his posts too).
