Niagara System

Hello all.

I have used Niagara systems in my scenes before, always premade systems as they do what I need them to. Since I moved to 5.3 however I cannot get them to display in the viewport.

Can you advise what I need to do to be able to visualise the particles. Attached is an image of the issue I am having, smoke seems pixelated and the fire just doesnt appear.

Thanks

David
