Features »» SMAA

Sub-pixel Morphological Anti-Aliasing or SMAA is a shader-based anti-aliasing algorithm created at Universidad de Zaragoza by Jorge Jimenez, Jose I. Echevarria and Diego Gutierrez with collaboration of Crytek’s Tiago Sousa. SMAA combines techniques used by Morphological Anti-Aliasing (MLAA) with other common techniques like MSAA/SSAA to remove jaggies while preserving image sharpness.

SMAA allows multiple levels of quality when programmed directly into the game engine. Unfortunately RadeonPro can only use SMAA 1x quality, but don’t worry as even at 1x level (see the comparison above), SMAA works nicely and usually better than MLAA or FXAA. SMAA is on par with FXAA performance-wise, without the downside of blurry text caused by FXAA and MLAA techniques.

As other post-processing effects in RadeonPro, SMAA can be toggled on and off with the press of a key.
