You can try enabling Async scene in the project settings.

https://docs.unrealengine.com/latest/INT/API/Runtime/Engine/PhysicsEngine/FBodyInstance/bUseAsyncScene/index.html

Then in the physics actors check “UseAsyncScene”

Dynamic objects that will block the physics actor need to have “CheckAsyncSceneOnMove” turned on. Otherwise static geometry will block them by default.

Good Luck!
