SMAA is a GPU-based subpixel morphological antialiasing implementation for DX9, DX10, DX11, and OpenGL, published as shader code (HLSL/GLSL) with precomputed lookup textures. It handles subpixel features and uses advanced pattern detection to avoid antialiasing non-edge texture details.

Use cases

• antialias edges in a real-time game renderer
• integrate post-process antialiasing into a DirectX 9/10/11 engine
• add SMAA to an OpenGL or GLSL rendering pipeline
• combine morphological antialiasing with multisampling or supersampling
• reduce jaggies without blurring texture details

When to choose

• you need efficient GPU post-processing antialiasing across DX9-DX11 and OpenGL
• you want MSAA-like quality at post-process cost
• you need subpixel edge handling and conservative pattern detection

When to avoid

• you need temporal upscaling or modern TAA-style reconstruction
• your engine already ships a newer antialiasing stack
• you need an actively developed solution with frequent updates
