I'm glad you posted these. Honestly, that first video is great to compare with the recent DriveClub Canada forest footage, and lets be real hear, in terms of lighting accuracy, shadowing, environmental scale, lushness, geometry, detail, scope, shaders, reflections, post processing etc, DriveClub pretty much walks all over ProjectCars, by a good margin. See here.

Comparing the two in the above doubler, ProjectCars lighting wise shares much in common with many current gen racers, it's quite clearly video game like, whereas DriveClub looks far more photo realistic, and in that small window often appears near life like. ProjectCars doesn't come close to replicating the level of realism showcased in DriveClub.
