v1.6 is out · free for Windows 10 and 11
optmzer gives Rust screen looks that light up dark corners, a zoom on one key, and a one-click FPS boost. Free, every change can be undone, and it never touches game files.
FPS in Rust with the Clean look, on our test PC
colour, plus NVIDIA Digital Vibrance
while you hold one key, up to 4x
looking at a 30,000-entity base, Max FPS look
Night lifts the dark parts of your screen, so walls, grass and anyone standing in the shadows show up. Drag the line to compare.
Night: the most detail in dark areas, while black stays black and white stays white.
Screenshots can't capture screen looks, so these pictures use optmzer's own colour maths on a real night shot.
Hold Mouse 5 (or any key you pick) and the middle of your screen zooms in 2x. Let go and it's back. Set it anywhere from 1.5x to 4x.
Fair play: Zoom and Dark Boost only change your screen, not the game. Some servers don't allow them, so check the rules where you play.
A minicopter flight over one of the biggest bases you'll see, on the Max FPS look with OBS recording at the same time. The counter in the corner is real.
Our test PC: Ryzen 7 7800X3D, RTX 5070, with Debloat and Trim background RAM done before starting Rust.
Drag the line. Left is Rust as it comes, right is the look you pick. Same spot, same PC (Ryzen 7 7800X3D, RTX 5070). Your numbers depend on your PC.
Clean keeps Rust sharp: low grass, legs off, and things load in from far away without popping.
No account needed, and nothing runs in the background unless you turn it on.
Checks your PC first and tells you what's holding it back, like RAM running below its rated speed or a 240 Hz screen set to 120. Then it tunes Windows for games and gives Rust three graphics looks.
Shows what's taking space before you delete anything: temp files, old driver installers, crash dumps, update leftovers. Your own files, games and passwords are never touched.
Screen looks that help you see in the dark, saturation up to 300% and NVIDIA Digital Vibrance. Set a different look for each game and it switches by itself.
Turns on the replay buffer, sets your clip key and quality, and splits game, mic and Discord into their own tracks. A small preview shows what OBS will look like before you apply.
Stop apps you don't need from starting with Windows. Anti-cheat, drivers and audio stay locked.
A light bass lift for your headset, with an "explain it simply" mode that shows what it does.
Turns off Windows extras you don't use. Undo brings every one of them back.
optmzer changes Windows settings and settings files, the same ones you can change by hand. It never touches the game itself.
The SHA-256 fingerprint of the current setup. Look it up on VirusTotal to see what every antivirus says.
Windows may say "Windows protected your PC" because the app isn't signed yet. Click More info, then Run anyway.
The basics are free forever. Pro adds the screen looks, zoom, bass and Windows tweaks, with 4 days free to try. No card needed for the trial.

Every Pro plan has everything: Colour looks, Zoom and Dark Boost, Bass Boost and the Windows tweaks, on top of the free parts. Plans add days on top of what you have left. Try it free for 4 days in the app, no card needed. Payments by Lemon Squeezy.
optmzer never touches, reads into or injects into game files, so anti-cheat has nothing to see. It changes Windows settings and Rust's own settings file, the same ones you can change by hand. Zoom and Dark Boost only change your screen, but some servers don't allow them, so check the rules where you play.
Every change is backed up before it happens, and Restore everything puts it all back with one button. optmzer can also make a Windows restore point before boosting. It never deletes apps or your own files.
Clean Up, Startup, the Rust graphics looks, the OBS setup and the FPS check are free for good. Pro adds Colour looks, Zoom and Dark Boost, Bass Boost and the Windows tweaks, with 4 free days to try it.
Big PCs still lose frames to background apps, power settings and heavy graphics options. On our Ryzen 7 7800X3D and RTX 5070 test PC, the Clean look went from 127 to 150 FPS in the same spot. The FPS check measures your own numbers before and after.
optmzer only runs while it's open. The Colour and Bass Boost helpers are tiny and only run when you turn them on.
No. You only need one for the Hub (friends, chat, sharing presets) and for Pro.
optmzer isn't signed with a paid certificate yet, so Windows doesn't know it. Click More info, then Run anyway. You can check the file on VirusTotal with the fingerprint above.
Press Restore everything first if you want all changes undone, then remove optmzer in Windows Settings, Apps. Your backups stay in case you come back.
