So, what profiling support is available to find the critical parts of your GDscript or C# code. Before needlessly jumping into c++ hassle for performance reasons? Tfa addresses functional reasons, which is ok.

I don't follow it that much, but I think there are no plans to improve GDscript performance other than maybe the interpreter itself, nothing with JIT or AOT in mind.

Also .NET integration has the issue it doesn't work in all target platforms, that is why Capcom and Unity have their own compilers to native code. Even when Unity finally adopts modern .NET, Native AOT naturally doesn't cover game consoles.

For C# there’s basically nothing in engine, so you’d use Rider or Superluminal. Which is fine, Godot can have a bit too much nih imo
