CMAA2 (Anti-Aliasing)

Conservative Morphological Anti-Aliasing 2 (CMAA2) is an anti-aliasing solution focused on providing good results while retaining the sharpness of the image at minimal execution cost. Originally developed by Intel.

It is very important to understand that some anti-aliasing methods can look great on some projects and not so great on others. So please take a look at the following feature list.

Pros:

• Works at a current frame only (no pixel jittering, no ghosting)
• Sharp and “old school” look (similar to SMAA)
• Supports both Deferred and Forward renderers
• Supports DX 11 & DX 12
• Supports Split-screen & PC VR
• Small performance cost (comparable to native TAA)
• Extra sharpness mode
• Quality presets
• Lightweight

Cons:

• Does not smooth out undersampled effects (noise from GI, Reflections etc.)
• Small subpixel details can still create some shimmer (Nanite meshes, dense foliage etc.)
• Not designed to be upsampled from Screen Percentage lower than 100%
• Vulcan is currently unsupported (working on it)
