All contact should be turned off for online, so you're effectively racing against other players who are ghosts, and they're racing against you as a ghost.
Is that your ultimate racing sim?
I seriously can´t tell when you are joking or not.
How did you survive past releases of Gran Turismo ? New customer for Polyphony ?
Yes I noticed this too...far lesser sawtooth edges in shadows as compared to GT5P.Just going off memory, the shadows seem softer and less jagged. There's also far less shimmering making it look cleaner in general.
Its not a demo actually, its just a time trial made for competition purpose only to show off the physics engine & thats it.The total size is 200MB, so its no wonder that its full of textures & assets that are even lower resolution than GT5P. Whats more, this track is equally bland looking in real life too so thats another reason why it looks even worse.
For those saying that the GT5 demo isn't a GT5 demo, I humbly refer you to this:
