Is it possible to run Rust without steam.


I’m asking this question as there are a few game that do run better without running though steam.
An example of this is STO for which I was a alpha and beta tester, But found running the game
though steam lagged the game somewhat.
There for I went for the downloadable client to run it. Which removed the lag.
So is it possible to do this, or will it be available in the future.

I’m not saying remove it from steam, just an option to run it without steam running in the background.
