It is very common to use “Affect Indirect Lighting While Hidden” to light your Lumen scene with invisible emissive materials, since this alows you to light up things without any extra perfomance needed. Driver576.02 completely breaks this feature for all UE5 versions, causing the light to be completely gone. This is a very crucial bug, as it breaks lighting for all games using this feature.
It is very easy to reproduce: just have Lumen enabled in your scene, add an emissive material to a mesh, and check “Affect Indirect Lighting While Hidden” and “Actor Hidden In Game.” When you switch to game view, the light is completely gone when running driver 576.02.
I am using an RTX 5070 Ti, but this very likely happens on more cards.
