I’m trying to make a 2d tile based game, I want to render the tiles that are only in the view projection (orthographic matrix). Basically I want to use this for culling, but I don’t know how to implement and make this.

You should simply not render them in the first place. You can use math on your frustrum to see if they are visible or not before you send them to get rendered.
