You're a Bedenkenträger, a "carrier of concern" :-) That's ok !
Aw, but if your PC can't run Unity you're likely to run into problems with Godot 4, too. It needs graphics that support Vulkan, so something post 2014 or so. Maybe you're lucky with a software stack on Linux, but that's not really an option for a modern day (at the time of writing :-)) game engine.
Apropos slow progression, if I am not mistaken - and somebody correct me if I am - Unity has an edge of 10 years over Godot.
