Anti aliasing

[eZe3ee]

does anti aliasing make the image sharper than 1080p on a 1080p monitor?

Anti-aliasing just smoothes edges.

Depends, supersampling anti-aliasing does improve sharpness because it is literally rendering the game at a higher resolution and then display it on your screen.

 

Others like fast approximate anti-aliasing might have the opposite where it blurs.

Depends on the type of AA.

 

Post processing types generally make things softer and blurry. However 'proper' AA can certainly help increase visual fidelity whilst maintaining sharpness.

The most demanding but most certainly highest quality form of AA is SuperSampling, which 'effectively' renders at a higher resolution, Nvidias DSR is effectively this.

 

4k DSR on a 1080p screen looks far superior to 1080p on a 1080p screen.
