To get a better perfomance, in general, you can check this tips that I know
If your meshes, foliages etc are already low poly it helps a lot.
*You can change the scalability settings in the editor, customize them to get the better graphic/perfomance you want.
*Using the World Composition to your landscapes levels.
*Study about level streaming, see tutorial here: UE4 Level Streaming | A Blueprint Tutorial by Devin Sherry - YouTube
*Uses culling to all your meshes and folliages (You can find it under LOD settings of the actor in your lvl, change the Max distance, you can see this feature working under play or “GameView”
*Reduces the textures resolution.
*Try to use static shadows, it takes a while to build, but it has better perfomance than movable shadows. If you need to use movable shadows, than take a look at cascaded shadows to improve perfomance.
*Try not to use too much post processing features, like DephOfField.
*Always has a LightmassImportanceVolume and PrecomputedVisibilityVolume.
Keep trying and trying. Good luck!
