Default TFS 5.0 Anti Aliasing Announcement

Team Fusion Simulations will be introducing two new AA options to the upcoming Battle of Britain flight simulator IL-2 Cliffs and Dover and the upcoming expansion into the North African theatre of war.

They are:

FXAA - Supporting 3 modes and quality settings (1 shader pass)

FXAA(Fast Aproximate AA) is a post AA mode that use blur filters. First, it detects contrasts ("edges") in the frame and then blurs it along the gradient.

This results in highly reduced visible "jaggies" that also covers alpha-textures, but it also blurs everything, including textures.

SMAA - 2 modes and 4 quality presets (3 shader passes)

SMAA is an AA mode based on the Post-AA blur filter of MLAA (and FXAA). The alisasing "detection" is upgraded and is closer to the detection used in MSAA then the detection used in MLAA and FXAA.

The result is that SMAA smoothes alpha-textures and greatly reduces the visible "jaggies", but doesn't blur the image as much.

Most experts say SMAA results in less blurring, cleaner edges and overall improved image. But it requires more processing power... so not for everyone.


Here are 1080p comparison images...

They make a definitive positive difference to the look of the sim.

Let us know what you think.
