Subnautica 2 FPS and Performance Boost (Disable Lumen and Post-Processing)

Features

• Disables Motion Blur, Depth of Field, Bloom, and Color Fringing.[/*]

• Potato PC Version (Max FPS): Completely disables dynamic lighting and reflections. This provides a massive framerate boost for older hardware, though interiors and water will lose realistic lighting bounces.[/*]

• Balanced Version: Disables Lumen but retains Screen Space Global Illumination (SSGI) and Screen Space Reflections (SSR). This keeps the game looking great while still providing a solid FPS increase.[/*]

Installation Instructions

• Download the version you want (Potato or Balanced) under the Files tab.[/*]

• Extract the downloaded zip file.[/*]

• Press Win + R on your keyboard to open the Run command.[/*]

• Paste your respective directory path below and hit Enter:
