It doesn't matter if they input nissan manufacture data if their simulation is coded to smooth out the riding and change parameters to make the cars easier to ride.

Even Jeremy Clarkson who gets paid by Sony to promote GT made a segment on how the game tweaks the way the cars handle. Laguna Seca, Honda NSX: in-game 1:41, the real deal 1:59.

So did Ferrari pay PD too?...

Now, there was article quoted the pro racers about the faster time in-game. I have to look for it, it was an old article.

The reason isn't because the cars are easier to drive in-game. It's because they know it's a VIDEO GAME, they drive more aggressive than how they drive in real cars. It doesn't cost anything if you brake late and spun out in-game but it might be really expensive in real life.

That was what the pro racers said in the article for the faster in-game lap time.

thanks god for competition, lets see GT5 work hard to match this game

I don't think that quite works the way you inteded it to work.

What that video shows is that you can replicate what a real driver did on a real race. In fact, Jeremy Clarkson could have replicated what he did on the real life Laguna Seca on his gaming rig. But that's not the issue here.

The problem goes when you try to go the other way, aka replicating your ingame commands in the real car, on the real track. That's not possible and it's what shows how PD tweaks the engine to smooth out things and make things easier for the player.

What you would need to bring down my post is someone scoring an absurdly good time on a track in-game (like Clarkson's 1:41 in Laguna Seca) and then try to do the same in the real track with the real car. 

They are both In Game, the one you are calling CGI is the "Video Editor" that users get together, do some tricks, and record it...

That Need For Speed opening is CGI and I agree, but everything I posted is In Game.

Like I said in the other post, the reason for faster lap time in-game;

No Fear

Fear in motorsports is a very interesting factor that isn’t given nearly the attention it deserves. Fear determines whether you will tend to under or overdrive your car and your abilities. My greatest concern with any student isn’t their experience or whether they have 800 million horsepower - it is whether they have fear. And watching someone play a driving videogame is a perfect example of why that is.

The best approach on a real track is to SLOWLY work up your speed around a corner to see what your car (and you!) are capable of. You want to work up slowly because if you race right in and discover you are 20mph too hot, you can crash, destroy your car and possibly yourself. In a videogame you just go, “eh,” and try again.

Videogames thus allow you to push yourself in the game more than you might on the racetrack. But it can also make you sloppy and tend to push harder than is proper for a good clean line.

I don't see decent gameplay in that movie.

It's not Descent, it's Forza.

I guess you missed all the talk with the Laguna instructor about the diferences in car behaviour while Clarkson was playing GT4 there in Laguna Seca and just ran with the first excuse =/

Anyways I understand you, if I had been waiting for so many years I'd be expecting the second coming and believing it too.
