To be fair, nearly all footage put up from any game is cherry picked, and it's frankly impossible to get identical footage from two games. The fact that photo mode pictures even come up at all is bizarre to me (unless games are comparing photo mode that is).
Racing games in general tend to look quite shitty in perfect lighting conditions, so it's why we like sunsets, dawn, night, weather, cloudy, overcast blah blah blah. I think the dynamic elements really play in DC, and Pcars favor.
Do we know what the replays add for DC in terms of added effects and IQ?
