FXAA (Fast Approximate AA) ​

FXAA is a post-processing antialiasing technique that analyzes the final rendered image to smooth jagged edges.

1. Pros & Cons ​

  • Pros:
    • Extremely low computational cost and requires no extra multi-sample buffers, making it ideal for mobile and low-end devices.
  • Cons:
    • Because it smooths pixel contrast in screen space, textures and fine details across the image may appear slightly soft (blurred).

2. Usage ​

Enabled via antialiasingManager.useFXAA. Enabling this automatically disables MSAA or TAA.

javascript
// Enable FXAA (Other AAs are disabled)
redGPUContext.antialiasingManager.useFXAA = true;
