I recently stumbled upon a fix to an issue that I have had for a long time while playing Rust.
Every time I would refresh the server list I would experience huge lag and my internet browser would become unusable.
I’m sure that this effects quite a few of you, so here are the steps to fix it.
Open Steam, go to Settings.
Click the “In-Game” tab.
At the bottom it will say “In-Game server browser: Max pings / minute”
Set this value to 1500 or lower and your lag should be greatly reduced!
