Module fxaa 

FXAA 3.11 — Fast Approximate Anti-Aliasing.

Single post-processing pass after all other effects. Detects high-contrast edges and applies directional blur along the edge, smoothing glyph edges without blurring interiors.

Quality levels

• Low: 5 edge search steps — fast, adequate for most cases
• Medium: 8 edge search steps — good balance (default)
• High: 12 edge search steps — best quality, slight cost

When to disable

• CRT scanline mode (scanlines + FXAA conflict)
• Player preference for crisp pixels
