Nvidia settings

I play on laptop , rtx 4060. Maybe no one here will relate to this but would be thankful if u guys can help . In nvidia app, terrain and object level of detail was recommended at 150 . So i had kept at 150 . But few days ago, in app it says 75 for both . Why its recommending so low now ? (I had installed inibuilds omdb which ofc couldn't be handled and i uninstalled) Because of this recommended settings got changed ?
