I founded this mod

It adds a ton of ships and planes. And Makes air traffic reasonable like in 1944. Can be on surface at day. Just like in real life.
Everything is great except 20 min loading times. I wish it had seperate campaing files like for atlantic only or something because now it has Mediterian Indian ocean Black sea and others.
Does anyone know a good way to reduce loading times? without removing mods
