As a console gamer, I don't notice it much, but it's probably because I'm not used to the fluidity/fidelity high end PC gaming offers. When I've seen a nice rig in action, I do notice how super smooth it looks compared to what I usually play (now PS4). However, I'm still not sure how low/bad framerate compares with bad frame pacing.
Favorite PS4 game is Bloodborne. DF calls out basically all From Software games for bad frame pacing and BB is no exception, but aside from the occasional stutter in high action areas, I don't notice the frame pacing issue. Ignorance is bliss, I guess.
