Console commands
Here is a list of console commands that you can enter in-game using the f1 button. Note that if entered correctly a print will appear below the command saying "True" changed to "Boolean" (false), this means it worked!

Each console command has a rating from 1 to 10.
1 being minimal, and 10 being maximum effect!

Order: ascending
Type in the line between each quotation mark. DO NOT INCLUDE THE QUOTATIONS.
-----------------------------------------------------
"global.fpslog 5".....(this command simply shows you your FPS every 5 seconds. You can change the "5" to any positive number you wish.)
-----------------------------------------------------
Rating 1 "gfx.damage false" ......(enable/disable damage indicators - no FPS boost).
Rating 1 "gfx.grain false" ......(disable radiation grain effect - no FPS boost).
Rating 1 "gfx.tonemap false" ......(removes tone mapping).

Launch Parameters
To use launch parameters right click Rust in steam, go to properties -> set launch options, and type in any of the following below.







Huge FPS improvements:

-force-feature-level-9-1

-force-feature-level-9-2

-force-feature-level-9-3

Minimal performance improvements:

-force-feature-level-10-0

-force-feature-level-10-1

-force-feature-level-11-0

Please note that these parameters may cause instability, crashes, or create graphical glitches. If you experience any issues just remove the launch parameters. I also don't recommend using multiple parameters at the same time.
Other Options
If you want to try and utilize all your PC's power try using these tips:

-------------------------------------------------------------------
Sometimes, a laptop will switch into a power management setting meant to conserve power and doesn’t switch back when it should have. Or you may simply have changed the power management settings yourself and then neglected to change them back later. In any case, it’s important to make sure that your laptop (or desktop) is using its high performance power profile when you are playing games.

-------------------------------------------------------------------

Shut down backround applications. You can do this manually, or you can save time and use gameboosters.

-------------------------------------------------------------------

Lastly, please make sure your PC or MAC meets the system requirements. If it doesn't then unfortunately you may need to upgrade your parts. If you're unsure what specs you have simply click on: Start (on the bottom left corner of your desktop), right click computer, and click on properties. Your computers information is listed there (instructions for PC only).

To save these commands I think you need to change the values in the CFG file.

@Buk Lau; open task manager >>> processes >>> right click Rust >>> set priority >>> set to high.

This should grant you a significant FPS boost. Report back and tell me how it runs, please.
