I don't get this.. what frame issues. Driving has been silky smooth on ps4 to me. Only place I seen this mentioned was on system wars type fan boy threads where they said ps4 had issues with a few frames in driving in traffic where x1 had issues with lack or foliage and frame drops during gunplay.
Personally I think, the Internet , and fan boys in particular egg this stuff on, and make it much more than it really is. All people in the real world that have played the game l, that I know never mention this stuff. Usually I see it with people who have an agenda.. either rooting for a particular console or downplaying consoles in favor of pc.
Personally I usually never notice frame drops unless it gets to the sub 20 range and it needs to be there for a while. Hell I remember playing and beating Crysis 1 with 17-22 fps on a 8800gts card and loved every minute. Pumping the eye candy up to max. Personally, I will trade in a few fps any day for better visuals, AA, and higher resolution... as long as it doesn't noticeably chug it's fine by me.
The only time a frame or two of drops really matter is fast paced arena games like Quake, or fighting games where one frame in lag can mean life or death, and even then it's usually from the net code not the games frame rate.
