What is FXAA Antialiasing and what does it do for PC Gaming?

**F**ast Appro**x**imate **A**nti-**A**liasing.

It smooths out jagged edges in rendered animation/screens. It’s also faster than some other methods and uses less CPU because it only smooths out edges as they appear on screen, not how they are actually rendered. It can also work on non-vector based images unlike MSAA (multisample anti-aliasing).

In games, it gives you a better image for less computational power which in turn means higher frame-rates.

Dont know about the fx part, but aa stands for anti aliasing. That means to smooth jagged edges in the image. Jagged edges occur when computer draws images containing edges. anti aliasing will smooth the jagges by either identifying the pixels sticking out and smoothing them, or by drawing the image many times with a slight offset, and superimposing them to make jaggies appear in slightly different locations in each picture, canceling them out.
