If you mess around with the framerate and cap in the video options here, you can sometimes make the BG3 animations appear like a sped up Chaplin flick, or kinda slow mo depending on the numbers. It's kind of inconsistent though, like at first I thought maybe the option would make it appear more classic cinema, or maybe soap opera video or something if trying like 28 or 33 or just messing about at the low end. But it seemed to speed up more at the high end. I was fiddling around with it the other day and noticing different impressions of speed, but then I ended up just resetting defaults again after a while, cause it started to wonk out a bit lol
