Foveated Rendering

Foveated rendering in Unity3D.
Eye tracking: Tobii EyeX.
Scene is rendered twice:
- Full screen with low resolution and blur. The geometry is set to biggest LOD (least amount of polygons).
- Small window based of the user gaze point. Rendered in high resolution (super sampling is possible as well). It also has Ambient Occlusion, Anti-aliasing and Gaze-contingent Depth of Field enabled.

Both are rendered to render texture and displayed on the screen. The HD render texture goes through a shader to soften the edges (make it look like a circle as the viewports are originally rectangular).

The following performance may vary and is measured on my laptop:
Traditional rendering with all effects on: 11fps
Foveated rendering: 42fps.

All the models are from the internet and I only cleaned them up and created multiple LODs for each.
