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?
1440p on a 27" monitor seems to be the sweetspot at the moment. But you also need to turn off all posprocessing effects like motion blur and film grain.
