What is fxaa in gta 5?

FXAA (Fast Approximate Anti-Aliasing) is a post-process anti-aliasing technique used in GTA 5 to smooth out jagged edges and reduce the appearance of aliasing. It works by detecting the edges of objects in the scene and applying a blur to the pixels surrounding the edges to create a smoother appearance.

FXAA is often used in video games because it is a more performance-efficient technique than other anti-aliasing methods that require more computational power. However, some players may find that FXAA blurs the image too much or reduces overall image quality compared to other anti-aliasing methods.

In GTA 5, players can adjust the level of FXAA in the graphics settings menu to balance performance and image quality. Higher levels of FXAA will provide smoother edges but may also result in reduced clarity and sharpness. Lower levels of FXAA will provide better image quality but may result in more jagged edges and aliasing.
