Are you actually getting in game? Or is it just showing an aerial view? If it’s showing just an aerial view of things and not actually loading in, then you should double check to make sure the mod is actually cooking out as intended after cooking out.
I had that problem at one point, and it was due to (I believe if I remember correctly) either cooking issues or command line issues (if you are trying to run it on a dedicated server).
The mention of 1 fps though throws both these possibilities off quite a bit as I never had that problem (if you are actually able to make a character, etc).
