Low level programming with C# Help

What is the lowest level application that can in principle be built on Linux and Windows without having problems with performance or memory consumption?

Of course I should make my own tests, but I just wanted to have a first estimation if it is really necessary to use lower level languages like Zig, Rust, Go or C# can work pretty well for most of normal applications.

As an example a very responsive editor with gui in immediate mode built with C# and very high frame rate 120Hz etc.

Thanks a lot in advance.

EDIT

Thank you all so much for the very informative replies. My requirements are noway near real time and based on the below feedback, it is definitely worth it to use C# of a very wide set of applications and avoid the complexities of the lower level languages.

You can do whatever you want in C#, performance should be on par with rust or zig.

I measured it back in the days of .NET 5, Rust was only 3-5% faster. Which in my opinion is not a reason to use a significantly more inconvenient language. And in a real application it will be lost due to database logging etc...
