CGI will always be ahead of ingame graphics I mean in game graphics now blow away cgi cutscenes from back in the day
I mean Final Fantasy Remake in game has better graphics than the advent children movie, but that Final Fantasy XV movie was next level CGI better than anything from PIXAR
PS4 PRO can do the cartoony PIXAR style in game at 60fps Kingdom Hearts 3 proved that, the levels look just the movies their from
There is no unpredictability to worry about for processing power, so gaming will always be some steps behind
