the problem with rendering the shit out of like even the rumble strips is that no one will ever see them, because they'll only be going past them at like a million miles an hour... like i only discovered today how cool some of the barriers are on gran tourismo. Also, that you can flash your lights and there's a horn, but thats neither here nor there.
Honestly I don't care how good it looks (although it DOES look good). I care far more about them fixing issues with matchmaking and the lobby system. A very close 2nd to that is the physics systems needs an overhaul. Some of the DLC cars have physics that are downright broken for the person that hasn't downloaded them.
