Frequently Asked Questions
What are the best Rust launch options for FPS?expand_more
The most effective are -high, -USEALLAVAILABLECORES, -gc.buffer 2048, and the effect-disabling flags like -effects.maxgibs -1 and -sss.enable 0. Use the generator above to build your string.
Where do I paste launch options?expand_more
In Steam, right-click Rust → Properties → General → Launch Options, and paste the generated string. Restart Rust for it to take effect.
Do launch options actually increase FPS?expand_more
Yes — flags like -high and -USEALLAVAILABLECORES improve CPU usage, and the effect-disabling flags cut GPU load. Combined with low graphics settings they can add 20–40% FPS on many systems.
Are these FPS commands bannable?expand_more
No. Launch options and the console commands listed here are all legitimate performance settings built into Rust — they don't modify the game and are safe to use.
What in-game settings boost FPS the most?expand_more
Shadow quality, water quality and grass are the biggest hitters. Drop shadows to 0, water quality to 0, and disable grass displacement for the largest gains.
