Hi all and Epic Team,
Here you are a comparison between Ray Tracing and Lumen. Lumen is showing some artifacts, like GI flickering on the reflected cube, reflection errors when Hit Lighting for Reflections is selected (look at that ‘squary’ white zone near the reflected right cube) like with less quality than Cache, or shadows pixelation near the base of the right cube:

Lumen Cache:
Lumen Hit:
And a lot of more issues when Hardware Ray Tracing is disabled:
