Using ghost line most of the time and turn it off here and there even when i know it is distracting me, but i want to know where i stand and trying to find different-faster driving lines.
And i'm using the bumper cam as i need the mirror in sight, plus it's the only view, where the rev gauge is useful for me and also the suggested gear help is in the middle of the screen which is better than search it on the side of screen. The chase cam, which i used a lot in first parts of game is pretty useless now, when i use DFGT. Here and there i use the interior view just to feel the "reality", but never in the online races.
