I’ve noticed there are sometimes subtle difference between both eyes reflections and highlights, on trees for example, which makes it harder to focus and/or which makes you thinking you’re not converging your view on the same objects. However the most distracting similar rendering artifact I can see is with lighting, where only 1 eye is rendering it or the 2 eyes are not rendering the same at all:
- Jump into the 787 at night
- Light up the glare shield
- Notice the rendering problem with the light cones over the glare shield
