Pixelated Shadows in Arnold

[Papriqua]

Hello there.

I'm trying to render out some shots of my character model, but the shadows are revealing the characters polygons.

I am using Arnolds aiStandardSurface material with an aiNormalMap node with inverted z instead of the usual bump node the material comes with. 

My Scene is currently lit by 3 aiAreaLights

Any help would be appreciated.
