So, I wanted to learn D3D11, but learning C++ at the same time would make that harder for me, and I have a time window of only 6 months to achieve that. I chose D3D11 because I mainly develop on Windows and DirectX works well with Proton on Linux as well.
Silk.NET is a very good C# wrapper of DirectX11 interfaces/methods so I can watch C++ tutorials and replicate everything in C# easily.
Quick comparison table of why I chose C#:
| C# | C++ |
|---|---|
| Easy | Hard |
| Slower | Performant |
| I already know it | Need to learn it |
| Uncommon in engine dev | Industry standard |
