I have a large architectural scene. I used a Blueprint construction script to instance 18 point lights as part of a chandelier. The lights are set to static. When i turn off “Casts Shadows” I’m running at 12ms a frame, but when i turn on “Casts Shadows” and turn off “Casts dynamic shadows” (leave on casts static shadows) and build the lighting the frame time jumps up to 19ms. Is this to be expected? Should static shadows affect frame draw time?
The 7 ms increase (with static shadows turned on) is just listed as an increase to “static opaque lightmapped” in the gpu profiler.
