It is odd considering it’s the same exact project. It seems the engine handles dynamic lights quite well. Not static well, but well none the less. I’m working on something right now using dynamic lighting only. There’s a ■■■■ ton of lights in the scene (About 30, most are casting shadows) and I’m still getting a solid 60~ fps on a GTX 970 in editor. It took a lot of optimizing, playing with render distances and fog, but I couldn’t go back to static lighting now.
