Were currently trying to build an island with blueprinted houses. After we placed a few of them, our FPS dropped insanely low and we dont know why. Our houses are really basic, they are built out of modular parts and all unnecessary tris have been deleted. We think the count of tris can not be the issue a screenshot of our statistics is attached to this post. We already tried to use LODs with a huge reduction of tris in really short distance but we didnt had a better result. We tried to turn off dynamic shadows and similar settings, we tried to turn down some render settings.
We’ve never worked with unreal before so we really just dont know what could be the problem. If you need more info in order to help us, just ask 
Thanks is advance.
