guys, I don't want to talk something wrong, so correct me if I'm wrong but.....did you notice the "developer diary #1" shows far better shadows effects projected on the car objects (mirrors, antennas, etc etc), and these videos didn't show such effects...I know it's wrote on the screen "work in progress" but....I don't know, just an observation...
Compare the first seconds on Dev. Diary #1 (onboard with Schumi) with the Pit Stop on Silverstone video...and you will see the difference...
Anyway, the videos are nice, the game seems to be far better to drive and the visuals are nice...in some parts of this video the track looks like the real Silverstone...amazing track quality...the cockpit is nice, it's not just a steering wheel and the driver legs, now you can see some tools there..
