Lethal Company: Best config.json for Scan Distance and FPS

The goal here is twofold: increasing your Scan Distance to spot scrap through walls from further away, and stripping away unoptimized post-processing effects to maintain high FPS during intense “Company Desk” sprints or flooded moon runs. In Lethal Company, FPS isn’t just for smoothness—it directly affects your ability to react to a Bracken or Jester.

File Path

Lethal Company does not have a native config.json. Instead, settings are stored in .cfg files generated by BepInEx. You must run the game once with mods installed for these to appear.

[SteamLibrary]\steamapps\common\Lethal Company\BepInEx\config\

• Graphics: HDLethalCompany.cfg
• Scanning: ScanTweaks.cfg (or CentralConfig.cfg for node extensions)

Technical Configuration (The 2026 “Lethal” Setup)

Open these files in a text editor (or via the Thunderstore Mod Manager “Edit Config” tab).

HDLethalCompany.cfg (FPS Boost)

[Graphics]
## Set to 0 to significantly boost FPS on integrated graphics.
EnableRes = true
## 1.000 is vanilla. Set to 0.923 for performance or 2.233 for 1080p.
ResScale = 1.000
## Set to 0 (VERY LOW) to disable shadows.
ShadowQuality = 0
## Set to false to remove the heavy volumetric fog.
EnableFOG = false
## Set to 0 to decrease poly count distance.
LOD = 0
## Set to 0 for lower texture resolution.
TextureQuality = 1

ScanTweaks.cfg (Scan Distance & Utility)

[Scanning]
## Increase the distance at which items are picked up (Vanilla is ~20).
MaxScanDistance = 60.0
## Increase how many items can be scanned at once (Vanilla is 13).
MaxNodesAtOnce = 50
## Set to true to scan through walls/floors more consistently.
IgnoreLineOfSight = true
## Show battery charge percentage on scanned items.
ShowBattery = true

Strategy for 2026 Performance Mastery

• The “Fog” Bottleneck: In 2026, volumetric fog is still the #1 FPS killer in Lethal Company. Disabling it in HDLethalCompany.cfg can result in a 40-60% FPS increase on laptops.
• Scan Node Limit: If you scan in a room full of loot and your game “hitches,” it’s because the UI is trying to draw too many icons at once. Keep MaxNodesAtOnce under 50 to prevent CPU spikes.
• Resolution Scaling: If you are on a 4K monitor, Lethal Company’s lo-fi art style doesn’t benefit much from native resolution. Set your ResScale to 1.488 (720p) for a massive performance gain without ruining the “VHS” aesthetic.
• CullFactory Mod: To supplement these config tweaks, install the CullFactory mod. It stops the game from rendering rooms you aren’t currently inside, which is essential for maintaining 60+ FPS in the larger “Dine” or “Rend” mansions.

Conclusion and Expected Results

By disabling Volumetric Fog and adjusting LOD in the HDLethalCompany.cfg, you free up the resources needed to triple your Scan Distance in ScanTweaks.cfg. You can expect rock-solid frame rates during high-action escapes and the ability to clear a floor of scrap significantly faster than a vanilla player.
