what is anti aliasing in games

Anti-aliasing is a technique used in PC games to smooth out the jagged edges seen in images, making them appear less blurred and blending the colors together. Aliasing happens when a curved line is drawn across square pixels, which is a byproduct of how computer graphics are rendered, as a pixel can only display one color at a time. Anti-aliasing attempts to smooth out aliasing by checking specific sampling frequencies and eliminating any under-sampled variables. There are several different types of anti-aliasing methods, each with its own pros and cons, including MSAA, FXAA, TAA, and SSAA. Choosing a suitable anti-aliasing technique can improve the quality of your visuals, but as displays continually increase resolution and image quality, anti-aliasing is becoming less necessary. Most PC games and graphics cards automatically enable anti-aliasing, and it varies from person to person based on several factors, including how graphically demanding the games are and what kind of gaming hardware is being used.
