AstraLex Shaders — Configuration

Configuration and Performance

AstraLex is highly demanding but offers several profiles to balance quality and performance. These are accessed via Options > Video Settings > Shaders > Shader Options.

Performance Profiles

  1. Low: Disables shadows and volumetric lighting; suitable for integrated graphics.
  2. Medium: Enables basic shadows and water reflections.
  3. High: Enables volumetric lighting, bloom, and high-quality shadows.
  4. Ultra/Extreme: Enables all cinematic effects, high-resolution reflections, and maximum shadow distance.

Performance Tips

  • Render Quality: Keep at 1x. Increasing this significantly impacts FPS.
  • Shadow Quality: 1x is recommended for most users.
  • Fast Render: Should generally be turned OFF as it can cause flickering or broken effects in AstraLex.
