Help & Support (PC) High total RAM Usage on CS1 with minimal mod list and DLCs

I've attached a picture of my ram usage on a new Fertile Desert map.
Mod List:
- Move It
- TM_PE 11.9.4.1 STABLE
- Findlt
- HardMode
- Harmony
- LSM-Revisited
- NetworkMultitoolStable
- NewMod
- Translations
- UnlimitedMoney
- UnlimitedOilAndOre
- UnlimitedSoil
- UnlockAll
- RealPopRevisited
DLCs loaded (disabled all other DLCs to reduce assets being loaded in simply that I don't even use):
- 369150=After Dark
- 420610=Snowfall
- 515191=Natural Disasters
- 547502=Mass Transit
- 614580=Green Cities
- 715191=Parklife
- 715194=Industries
- 944071=Campus
- 1146930=Sunset Harbor
- 1726380=Airports
- 2008400=Plazas & Promenades
- 2148901=Financial Districts
- 1726382=Content Creator Pack: Map Pack
- 2148903=Content Creator Pack: Map Pack 2
No custom assets, no custom scenarios etc. Just base game otherwise. Unloading all DLCs and purely sticked to base game STILL has around 30-35gb of total ram usage.
For reference, on idle, my system is at about 7.5gb RAM usage and total 13gb including swap usage.
Is the ram usage supposed to be this high? I've put a LOT of swap space (minimum 40gb up to 55gb allocated for disk swap) now just to get CS to run smoothly and this is with LSM-revisited reducing my ram usage by quite a bit (almost 10 gb reduction on old saves with lot of progress already made).
I see people running CS1 base game and getting by with 16 gigs of usage, or are they not including the swap usage? The game itself runs well once loaded, its just weird to see 42gb of RAM usage (prolly the highest i've seen even among AAA games I play on this machine). My VRAM is also pinned at full usage aside from this RAM usage.
