Any Grafix doubts. I think not

[Johnny]

My only complaint about the graphics is that I think people shouldn't fret about the wheels. I mean, I'd rather play a damn-near lifelike game like Gran Turismo 4 than to worry about something as little as rims. To me, it's like adding fuzzy dice to a car- doesn't make a difference to performance. The graphical doubts are pretty few for me. I don't expect the game to have 60 FPS and have no pop-ups or slight slip-ups. I'm not bothered if you ask me. If it isn't broke, why fix it?

I see your point on wheels.

But you are wrong when you say wheels don't make a difference in performance. Actually the wheels + tyres setup makes huge difference in race cars. In GT3 you can only select the design of the wheel right? So there's no difference in performance, as what makes the big difference are the tyres (Normal,Sports,Racing,...)

Anyway, the size of the wheel+tyre (diameter and width), on the "real world" really makes difference, because this influences in such a way in the comfort of driving as in the performance. For example, a car with wider tires possesss greater area of contact with the ground and bigger tack and greater aerodynamic drag. This car will have conditions to pull out better than another car with narrower tires, and of course will have more stability in the curves, but will lose in final speed due to the biggest attrition caused by the biggest contact of the tire in the ground and with air. Logically, in this example we take conditions equal, since some other factors exist that influence in the performance.

A example for a normal car:
If you buy a car with a 165/60/15 Wheel+Tyre setup and replace it with a 205/40/19 makes the car go around 10% faster. So if you were at 100Km/h on the 165/60/15 setup, if will be at 110Km/h at the 205/40/19 setup. This happens because the ray, diameter and circumference of the Wheel+Tyre increased. This does not mean gain in hp, but the car will reach to a certain speed faster than before.

This is a good reminder to those who like huge wheels with wide tyres on their cars. Go re-calibrate your speedometers, as they are not giving you the right speed you are driving. For your own safety, and the safety of your wallets (nobody wants to get fines).

I think he was talking about the graphics of the wheels/tires. Not the performance of the wheel/tire itself.

I know. I just though he would like to know that on the "real world" it does make a difference.

On the GT series, performance is gained with tyres, with wheels being only for cosmetic purposes (something he was complaining, and that i agree with).

I posted a while back that the "cuda" replay appeared to HAVE 3d wheels. Anyone else wanna check it out and give their opinion? I may be incorrect [wouldn't be the first time], see for yourself!

Bump? Anyone review the above mentioned video?

As for the vid, haven't seen it myself but I'll go out on a limb and assume it uses the same sort of layered rim structure we see in GT3 and some shots of GT4 that gives a reasonable illusion of 3D because there is indeed depth to some aspects of the rims, but they're still just a number of flat layers in reality.
