ELI5- why can movies make CGI human faces and movements that look 100% real and normal but video games always look fake even with large budgets?

Movie don’t use your GPU or processor to process the CGI.. you just play it with your media player.. while video game depends on your budget which GPU and CPU did you buy..
Its like you buying a bread at shop and just eat it compare to you buy the ingredients and make it..
Movies have teams of artists that stress over every single frame of a film, and can spend days or weeks working on a single shot using farms of high-end rendering equipment. It’s an intensive process that takes much longer to produce than it takes to play out on-screen. A video game’s footage is ultimately created by a single consumer-grade computer that only costs a few hundred bucks and has to render a human face in real time, at one second per second, with no direct artistic intervention.
Because the movie can spend hours or days making a couple frames, whereas your computer needs to crank out 60-120 frames per second.
TLDR – Video games don’t have the clean up operation at the end by someone paid to fix the fakeness of movements
Even if the movie starts with a character that walks across the surface procedurally like the video game there’s still going to be an animator who watches the results and fixes any jank. Walking along, steps on a rock, and just sorta warps upwards? Well let’s fix that and bend the knee a bit more right here
Video games don’t have someone watching it and they’re a lot more freeform. If the character model just doesn’t conform properly to lumpy ground then it just won’t conform to lumpy ground. There are too many possible animation/terrain/movement combinations possible in video games to test and fix 100% of them especially once you start allowing people to customize their character
