How to optimize render settings to speed up renders of black and white moire patterns in 4k? I'm using Blender 2.79b on a laptop with i7-4700 4 core processor with 16GB of RAM with on-board graphics. I'm trying to optimize my render animations to render out in 4k. I don't have a GPU on my laptop. Can someone recommend some render settings that will speed up the render process? The image is black and white. I'm animating different moire test patterns.

Here's a YouTube link to the current animation done in a 480X480 resolution:

I know the render settings for 4k (see image below) the issue I have is speed and how can I increase it by turning certain render options off.



I've also included the blend file:



Since it's basically a Black and White animation I'm open to use any render engine, which ever render engine will speed things up.
I turned off Freestyle rendering, raytracing, textures, FSAA (full sample AA), set all materials to shadeless. And finally I set rendering Tile Size to 1024px.
