Can we get some map optimization?

Savannah map in particular will average 50 frames (worse with Delirium fog) without any mobs on screen while there are other maps I can open a Breach and barely dip to 50 FPS. Dynamic Culling doesn't help. Performance vs Quality DLSS doesn't help. It's just straight up the map. Anyone else got some maps they notice bad frames? Savannah just seems to happen really often and is the most obvious as I can recall.
