MSAA is best suited for midrange gaming computers. Also, choose MSAA if you are looking for a perfect balance between performance and quality. Multisample Anti-aliasing (MSAA) produces one of the best image qualities and is much faster than SSAA. FXAA is perfect for low-end PCs because it is less demanding on your PC.

Which anti-aliasing method is best?

FXAA. Also known as Fast Approximate Anti-Aliasing, FXAA was crafted by Nvidia. When it comes to anti-aliasing on low-end devices/PCs, FXAA is the best technique. It's because, in terms of hardware or GPU, FXAA is not that demanding.

Is FXAA or MSAA 4x better?

Coverage Sampling (CSAA): Nvidia's more efficient version of MSAA. ... Fast Approximate (FXAA): Rather than analyzing the 3D models (i.e. MSAA, which looks at pixels on the edges of polygons), FXAA is a post-processing filter, meaning it applies to the whole scene after it has been rendered, and it's very efficient.
