PSUni: The GT Academy finals are currently underway and one advantage for us mere mortals (who don't quite have the skills of these top racing gamers) is that we get to have a look at the latest build of Gran Turismo 5. Sure, many us played the Time Trial for the GT Academy, but we understand that much of the graphics engine wasn't updated from GT5: Prologue, only the physics were.
So with the following low-quality video of the GT Academy finals in France we can get a good look at the Fuji track that we've previously enjoyed in Prologue. As you might be able to see, the track and roadside have seen an impressive upgrade in texture detail. Also the game's lighting appears to be improved over Prologue, one of Polyphony Digital's many strengths, though this could be a side-effect of the capture method used to take the video. So here's a comparison about what we're talking about.
