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.
