I’ve been messing around with creating a basic 2D platformer. I started off just using orthographic projection and everything looked fine, but after looking for ways to create a parallax effect it seemed like switching to a perspective view would be simplest. But doing that has made all my sprites look quite blurry, which is a big problem as my art style (such as it is; I’m no artist) relies on clean, sharp lines. As far as I can tell, switching from orthographic to perspective is the cause of this.
Does anyone know why this might be, and how I could fix it? Any help would be much appreciated 
EDIT: On closer inspection, it’s really only animated or rapidly moving sprites where there’s a significant difference. It’s as if there’s some sort of motion blur or something?
