Since the San Frisco mod (Repo link) is unsupported and the author @JonasTMT is inactive, so no fix by him, I fixed it myself by request. The buildings and logs have textures now, Ram usage was about 20GB and went down to 6-7, not sure if this was an issue before the textures were broken, but it is gone now anyway. There are still some messages in the console but I couldn't see any visible errors anymore, tell me if you spot something.
I fixed the dealership and some other stuff, a new file is in the main post. The console is basically empty now. The skyscrapers are working fine for me, you may need to clear your cache. The terrain issues are fixed as well, they were so bad it broke the terrain painting tool.
