Everyone has their own view, but the games arent in the same league in my view. Especially the weather.
Hmmm. The weather in Drive Club is far more realistic. That's been known since release, unless p/cars has improved theirs dramatically. It may well have, because I haven't bothered with the weather in project cars since first getting the game, as it was an instant disappointment after playing in horizontal rain and snow in DriveClub.
Project cars has more detail and better physics. DC has better weather, but also a very. very nice look for what you need to see, as Swanny puts it. Do you own DriveClub? If you're playing P/Cars on a 970, then that's not comparative opinion, just hardware based appraisal.
Project Cars is a much better game IMO, but simply stating "easily better visuals" appears a little disingenuous.
