I had many textures of random objects like trash, magazines, vending machine displays, etc have extremely pixelated and blurry textures. I figured out why. For some reason my graphics and video settings were altered by themselves where I had my graphics preset set to low and my resolution set at 1600x900 when I had them much higher. Once I more or less returned them to how I had them. (Preset on HIGH and 1920x1080). The graphics were sharper as they were before I experienced that blurry look.
So If you were experiencing extremely blurry textures on models and surfaces when it wasn't like that before, go through both your graphics and videos settings.
