I’m working on shaders using a scenecapture2D actor and noticed a boost in fps when I uncheck “Deferred Lighting” in the advanced show flags of the scenecapture settings.
I’ like to know what is exactly happenning when it’s unchecked: does the engine uses forward lighting? And why does it boost fps?
Also I noticed that metallic materials were incorrectly lightened when unchecked: why?
I found nothing about it in the unreal doc.
