Especially with details like fur or hair. I'm used to older games having blocky and angular (more or less depending on when they were made) models with jagged edges due to aliasing with simple transparency effects used for stuff like hair.
Modern games just look less defined up close. Is it a bunch of post-processing effects? Does my monitor have especially chunky pixels?
Temporal anti-aliasing has replaces traditional anti-aliasing. It's much less computationally expensive, but it tends to lose sharpness, so it requires an artificial sharpening filter. It's also an average between frames, so cutting between scenes and moving the camera quickly reveal additional artifacts.
