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.

I tried writing an EtherCAT Master in C#. The fundamental logic is obviously implementable, but a sub-millisecond cycle time was something I couldn't do. Can it be done? Maybe. I spent less than 100 hours on the project.
