Overview
A clean and stable image is very important for the perceived graphics quality. CRYENGINE offers a highly efficient post-processing based anti-aliasing (AA) solution that can be controlled with the CVar r_AntialiasingMode. Anti-Aliasing and its effectiveness can vary from user to user as some prefer a very sharp image, whilst others prefer a blurrier image, this is why we ship with several options to suit the users needs.

AA Mode | Value | Description |
|---|---|---|
No Anti-Aliasing | 0 | Disables post-processing based anti-aliasing. Mostly useful for debugging. |
SMAA_Low (1X) | 1 | Enables Subpixel Morphological Anti-Aliasing (SMAA) which removes jaggies (staircase artifacts) at polygon edges. |
SMAA_Med (1TX) | 2 | Enables SMAA with basic temporal re-projection to reduce pixel crawling. |
SMAA_High (2TX) | 3 | Enables SMAA with an enhanced temporal re-projection including matrix jittering. Usually this mode provides the best image quality but can suffer from some occasionally flickering edges. |
Supersampling
In addition to the post-processing based AA, CRYENGINE supports supersampling for very high quality rendering. Supersampling renders the scene at a higher resolution and downscales the image in the end to obtain smooth and stable edges. Due to the high internal rendering resolution, supersampling is very performance heavy and only suitable for high end PCs.
