Paper 2D Flipbook quality in perspective

Hi all

Im having problems getting my 2d game to look nice with a perspective camera, when in orthographic mode the paper flipbooks and sprites all display nicely, but when in perspective mode they become slightly flickery and blurry.

This is a pain because I was hoping to use perspective to get parallax in the game.

Does anyone know what might be causing this issue?

It is recommended to use an orthogonal camera, and you need to write a parallax system (for example, add a remote actor to an array, then move slowly as the protagonist moves. Add the close range actor to another array and move faster as the residence moves
