LethalOptimizer v1.4.1

Performance optimization mod for Lethal Company on low-end PCs.

⚠️ Warning: On powerful hardware the effect may be minimal or unnoticeable. This mod is designed for weak devices. ⚠️ Warning: I don't have the opportunity to test the modification in detail, so there may be errors.

What's New in v1.4.1

Fixed:

• Configuration System — removed master switches that were blocking individual optimizations
  • Previously only EnableAllOptimizations worked, other settings were ignored
  • Now each optimization can be toggled independently

Improved:

• Logging System — better visibility of active optimizations
  • Shows count of active optimizations per category (AI: 15/18, Items: 4/4, etc.)
  • Displays which core features are enabled (Distance Optimization, NavMesh Cache, etc.)
  • Clear indication of total active optimizations

Changes:

• Removed non-functional master switches: EnableAllOptimizations, EnableAIOptimizations, EnableTrapOptimizations, EnableShipItemOptimizations, EnableInteriorOptimizations, EnableNetworkOptimizations, EnablePlayerOptimizations, EnableObjectOptimizations, EnableUIOptimizations
• Simplified configuration structure — only functional toggles remain
