I actually found my fix, though I’m not sure which one did it but I’m sure they all contributed.
1. I used bulk rename to take out all special characters and spaces in my mods folder.
2. I deleted all high poly cc
3. I cleaned out my cache before EVERY initial load.
4. I waited on the main menu for at LEAST 30 seconds, opening the packs and the kits tabs.
5. I loaded into the game BEFORE opening any other programs.
With only CC and MCCC, my game loaded in 4 seconds.
With my entire 10gb mods folder, it took the exact same time, 4 seconds.
The pie menu is also almost instant, before it would take around 2-3 seconds to pop up.
I’m not sure if this will help anyone else, but those 5 fixes combined fixed it for me.
I believe the biggest contributor is letting the game stay on the main menu for a bit before just jumping in.
