Lethal Company has a small options menu, but a few settings decide whether a run feels smooth or frustrating. This is the short list that matters.
Graphics — where the FPS actually is
The game renders a lot of physics-driven objects (scrap, enemies, weather). The settings that return the most frames:
- Shadow Quality → Low. Shadows are the single biggest cost when the base is full of items.
- Shader Quality → Low.
- Volumetrics → Off. Fog and light shafts are pretty but expensive in enclosed, item-heavy rooms.
- VSync → off unless you see tearing; it caps you to the monitor refresh and adds input lag.
- Resolution scale down a notch only if nothing else helps.
Leave Anti-aliasing on — turning it off makes thin wires and ledges harder to read, which gets you killed more than a dropped frame does.
Keybinds worth changing immediately
The default two-hand grab is awkward. The bind players change first is mapping grab/use to a mouse side button so you can hold a weapon and still interact. Other common remaps:
- Jump and crouch to mouse side buttons for mantis-style movement.
- Ping/scan somewhere you can hit without dropping your item.
- Voice chat off the default if you keep accidentally keying it.
Voice chat and the boombox
Voice is push-to-talk by default. There is a mute toggle and a full disable in audio settings. The boombox plays music for the whole team and is the usual alternative to voice when someone does not want to talk.
Sensitivity and movement feel
There is no aim-down-sights, so mouse sensitivity is purely camera speed. Most players run it a touch lower than a shooter default because the game rewards precise ledge reading over fast flicks. Change it in the controls menu, not a config file.
Launch options
The game itself takes no special launch flags for normal play. Mods such as r2modman handle their own launch through the mod loader, so you do not need to hand-edit Steam launch options unless a specific mod tells you to.
