I surprisingly found the handling of the cars of GRID 2 at 30fps more responsive/realistic/fun than with GT5 at 60fps.
I really hope they try to mimic GRID 2 driving... not the crappy driving seen in NFS rivals.
A lot of people get confused when comparing games to NFS series. NFS Shift 1 and 2 which are TRACK based SEMI SIM had great handling like the Grid games. Open country Fast and Furious type games like NFS Rivals, Forza Horizon etc are kinda lame regardless if they run at 60fps.
The question is what type of game is DC?
From what I've seen so far it looks to be closer to the Fast and Furious type of driving games.
