D and C++ renderer side by side demonstration

Here is a youtube

I was watching Timur Gafarov’s videos on Dagon Engine and 
stumbled upon a video that demonstrated a C++ Renderer Engine 
using the same Sponza scene. I thought it would be a great idea 
to show them side by side.

This is not a “X vs Y” video! It just demonstrates the 
capabilities of D and C++ side by side.
