Leaky for your own sanity, turn down the lightmap quality on most of the map, especially the bigger parts and the bigger buildings
You can assign lightmap groups to retain your higher quality for indoor areas and such
Also don't try to lightmap HUGE or very far away objects like the water or the distant buildings. I think if you turn off "Lightmap Static" on the water and on those other objects you would save a lot of VRAM and map size because holy fuck 900 MB is too much
