Iirc it was a stupid C-suite decision to use Frostbyte across EA studios. It never made much technical sense and DICE lacked the bandwidth and capital to support so many teams and usecases.

Yes after the success of frostbite around Bad Company 2 and Battlefield 3 or so, EA decided it should be used in everything. Not unlike the mistake Capcom is making with REngine right now, if the performance woes of Monster Hunter Wilds and Dragons Dogma 2 are anything to go by.

Pretty sure there was even a Need for Speed game on Frostbite which was... huh.
