FXAA is effectively the console alternative of MSAA (the x2, x4, x8 options) It uses less resources, but can have the effect of more blurring of the image. MSAA and FXAA both work in different ways, so both can be used together, but it is not really necessary as the average user will not notice the difference. If you are limited on resources, turn off MSAA totally and only use FXAA.

Sorry for the double post. In summary, it is anti-aliasing. Having it ticked will lower performance.

FXAA is the cheapest form of anti-aliasing that actually makes a difference. Check it if jagged edges bug you but MSAA hurts your frame rate too much, uncheck it for best performance or if you don't like the slight blurring (personally, I don't like FXAA that much, but I prefer it to no AA)

Can someone concisely explain anisotropic filtering to me?

Yeah performance wise, you would choose FXAA over AA, it works similarly, the difference is near negligible, and it might improve your fps. Test it out, turn it on without AA, check fps, turn it off and turn AA and check there.

basically it rounds out polygons.

No AA = a ring may look like a octagon

AA = a ring looks more circular

That is anti-aliasing.

 

Anisotropic Filtering can be summed up by this image: http://upload.wikimedia.org/wikipedia/en/c/c0/Anisotropic_compare.png

The left side is no AF the right side has AF.

it's the level of texture quality. Higher is better. For a detailed explanation, look it up on wikipedia.

Yeah, what Jason_Ryu_3 explained is anti-aliasing.
