the graphics engine in this game is pretty old so everything except the cars looks kinda bad. Its just the nature of the game.
you have to be a troll. If you aren't a troll, then Ultra settings are currently the best, it's not going to hurt to try.
That's what cars look like when they are new from factory though. I know it feels kinda weird, but the game doesn't have any proper dirt implemented yet or anything like that, so you're stuck with this effect for now.
Take a look at the SBR4 AWD TT S2, it's default color is normally a very matte blue, if it isn't matte there is a problem on your side.
LoL --- This old mans 47 I realize you did not ask me. Found it pretty funny though . My wife would say I am the kid she never asked for
