Problems starting Rust.

Well balls. I saw a thread on how to increase your frames by putting in codes into the launch parameters and well, it fucked up my Rust. Can anyone help me with this (Ahem Garry)?
Btw here’s the link to the supposed “FPS Increaser” forum thread:

Just open the Set Launch Options in Properties and remove everything, right…?
