Sadly you can't seem to understand that the game and lighting parameters aren't finished yet.. and those are actually my screens, which I posted for the IQ comparison to the Driveclub ones not for realism. Post Driveclub pics at that IQ (that aren't dev bullshots) and compare. It's easy to say how realistic DC's lighting and environments are when you have really shitty compressed pics that blur everything together. When you see those assets in their unblurred glory, their flaws will flow through.
I can go into the debug menu and play around with parameters, and lighting ect.. Of course the most important thing to remember is that the game is NOT finished yet... and there will ALWAYS be lighting conditions that look more realistic than others in every game. Shaders need to be adjusted and tweaked for different lighting conditions. On a game of this scale, it would be very hard to have the same quality across the board. I think you are being a little too quick to judge. I can post extremely game-ish looking screens of pCARS, and I can post extremely realistic looking ones. Give the devs a chance to tweak and fix things. We both know the game can look extremely realistic, no reason to think they wont tweak things to make it look more realistic in all lighting conditions. They are still building content for the game, most tracks aren't even close to being finished.. they haven't even thought about seriously tweaking and adjusting things yet. If I hadn't been there since the start and seen how things have improved, I might think like you, but when the tracks are done, they will look great, I'm confident.
Some shots of the debug menu and other shots:
Now look at this pic:
One looks much more realistic than the other, of course, but the lighting isn't done. I'm 100% confident they will adjust it
