Wherever you mess with this setting, just set it to 16x as this setting has little to no performance impact. It’s rare that players will have to adjust this setting from the Control Panel for games like Horizon Zero Dawn as the in-game “Anisotropic Filtering” doesn’t work. Enabling Anisotropic Filtering eliminates this blur and makes those ground textures look crisp and clear. It is best to meddle with it in-game than in the Control Panel.Īs for what it does, if Anisotropic Filtering is disabled, players will notice that textures on the ground are blurred. Anisotropic Filtering is a common graphical option found in PC video games.
