@nprofile1q... You're right, GDScript is incapable of handling a lot of decently intense workloads either. And I believe in both Unreal and Godot, it holds some games back because some devs can't help themselves otherwise.
As for Unreal, Epic proves those right who make their own engines. Godot may be FOSS, but if its devs decide to become stupid, you need a group of other competent devs to make a fork. It's not a one man project.
