  • Boosts FPS, which is a huge win for performance on any rig.

⚠️ Cons

  • Requires a clean install and careful load order—messing up can cause crashes.
  • May conflict with other mods that alter precombines, so compatibility is a concern.
  • Last updated July 2026—if you're on an older game version, you might need to check compatibility.
