What book was this? As far as I recall the FRCS was 3E.
"Player’s Guide to Faerûn is a sourcebook for the Forgotten Realms using the Dungeons & Dragons 3.5 edition ruleset. It updates many rules from the 3rd-edition Forgotten Realms Campaign Setting and provides additional and update spells, magic items, and prestige classes; expanded cosmology; psionics lore; adaptations for Book of Exalted Deeds and Book of Vile Darkness; and more."
It tried not to retread too much from 3e's FRCS because not that much changed and unlike the SCAG the FRCS was fairly comprehensive, although the PGtF expanded upon that and updated things that changed and filled in some blanks.
A 5.5e Setting book for FR will have ALOT more to do as alot has changed since the SCAG and the SCAG was extremely scant on details, not even having a proper full detailed map of Faerun!
