lumen optimization question regarding probes.

I have questiosn regarding lumen optimization.

with
r.LumenScene.Radiosity.ProbeSpacing
r.LumenScene.Radiosity.HemisphereProbeResolution
r.Lumen.ScreenProbeGather.RadianceCache.NumProbesToTraceBudget

i see no effect using any number value on any of these… other then probe spacing if i use the debug view of “r.Lumen.Visualize 1” … in the actual scene i see no difference… the debug command i only see a difference in probe spacing… again not in the actual scene so it seems pointless.

So whats the point of any of these? I start my scene in high or epic settings and under those they do nothing at all in terms of improving or degrading the visual of lumen.

These only affect the Lumen scene, they should be noticeable in glossy/mirror reflections but I would not expect it to make a big impact on diffuse GI in most scenes

I don’t think this would have any impact on quality, just lighting responsiveness.
