    I use refprobes to anchor diffuse objects in a scene, think of it as a quick way to get dynamic 1 bounce global illumination.
    So 16x16 is all I need.
    Since these get updated at runtime each time a building is moved, the lower the res the better, even 4x4 is enough to get a good anchoring.

    At theses low resolutions youre not gonna get any appreciable performance improvement from switching to 16x16 or 4x4. Most of the performance hit is on CPU side, culling and drawcalling. In fact switching to lower resolutions might make it even slightly worse due to how rasterization works.

    Interesting.
    Maybe it's optimal.
