I'm not an expert but I feel like I remember hearing that low framerate high frametime feels worse than low framerate low frametime. Something to do with the delay it takes to actually display the low framerate?
As some of the other comments mentioned, it's probably also the framerate dropping in general too.
A similar vein as this, at work I was talking about a heat gun:
"Look, the feet are molded into the cable so if you break it you have to buy theirs!"
I then pull the cable out to show it as an example and snap
I didn't realize it had a retention clip at all, so I lightly pulled it and snapped the thin plastic holding it in. I thought it was held in by friction.
Don't you understand? That IS the gameplay! You act out the entire cutscene with the most in depth and engaging control scheme Rockstar has ever developed! (tap A for 5 minutes to talk)
I think it has something to do with frame times.
