Fxaa3

After reading this thread, I thought I'd have a go at converting the latest version to Unity, FXAA3. It seems to work, but is a fair bit slower. Here is an example of the results:


And attached is the shader/script for the effect (needs Pro, of course, and is based on code Copyright 2010/2011 NVidia Corporation - full disclaimer in shader source).

Edit: removed a redundant texture read that was annoying me.

*** Newer version in post #6 ***

 

Are the results better than the included AA image effect?

 

What the difference from the previous FXAA (from Slin)?

 

Here you go (I only wrote it as an exercise anyway):
(all times are recorded on a PC with a Radeon HD5750 in deferred rendering)

NoAA (3.4ms/frame)

Edge Blur - built-in and most adjustable (3.9ms/frame)

FXAA2 from Slin (3.7ms/frame)

FXAA3 (3.6ms/frame)

 

So the third version is sharper? hmm interesting. Thanks for sharing this, i'll check out.

Here is the Unity port of the console version of FXAA3.11. It is approximately the same speed and quality as the last version ( based on 3.8 ), but is tweakable, unlike the last version.
