Supersampling is a brute-force AA method that calculates a pixel's color by forcing the GPU to oversample the frame, or render it at dimensions equal to the resolution times the sampling rate (ex.: native resolution of 1680x1050 * 4 samples = 3360x2100) and obtaining color data from samples around a target pixel before downsampling (reducing) the frame to its original size. After the frame has been reduced a negative level of detail bias is applied to sharpen a sampled object's textures to counteract the blurring that downsampling and pixel merging produces. Supersampling is a type of full-scene anti-aliasing, meaning that every pixel in the frame is sampled and corrected rather than just those lying on the object's outer boundary, lending it to offer exceptional image quality but at an enormous cost to performance due to the GPU being required to compute so much additional information.

Supersampling produces the best AA results, at the highest performance cost. https://www.youtube.com/watch?v=8fYuKusjtY8#t=68

Amnesia has no AA, which may be the case with some titles. This method might be preferrable in those cases, in order to achieve AA (as long as your computer can run it). If the game has AA you're more often better off using the game's native alternative as that will be better for performance.. Unless that alternative is FXAA, in which case one may want to use SSAA instead.. Just personal preference as FXAA can blur textures (blur all the things!):

As you can see, FXAA 'loses' all of the specular highlights when it's shown in the gif. You can also see the right shoulderpad becoming blurry (as well as some textures on the back becoming blurry).
