No, I don't believe I am.
Right, but someone with a Dodge viper is not going to see the exact same weight loss. In GT5 no matter what the car is, it is the same exact weight loss.
As I said, the "other" game uses aftermarket parts from real manufactures who supplied them with the data for said components. Every car does not use the same generic aftermarket parts for every car, ala GT5. Gran Turismo is the game that makes blanket assumptions, while the "other" game tries to use individual data per car and part.
I think we're saying the same thing (or at least have the same outlook) - that the tuning is unrealistic and unrelated (in large part, not entirely) to the vehicle specifics.
You're saying applying additional characteristics (weight loss from cf drive shaft and weight gain from chassis reinforcement, etc) would improve the level of realism. I'm saying (for the same reason - that the vehicle tuning is generic and not based on individual vehicle characteristics) that those characteristics would still be arbitrary and wouldn't necesarily improve the level of realism.
Fundamentally, the issue is still PD's implementation of tuning, which is very topical.
What I would
like to happen is have the tuning adapt a more serious approach, and actually have it modeled with as much detail as they try and put into the particular cars. I don't know that this will ever happen though.
Yes, it does make the physics less accurate. I honestly can't believe that you can even try to argue that it doesn't. Actually I can prove how it makes it less accurate.
Weight-shift...
If the weight is not being calculated correctly then resulting weight-shift will be inaccurate. Therefore, the handling is not being accurately portrayed.
Look at the physics of a stock vehicle and then compare it to the physics of a vehicle that has had a cf drive shaft and chassis reinforcement upgrade done. You're focusing on the the fact that the car will not reflect a higher center of gravity and additional weight from the roll cage, only additional chassis stiffness and faster engine acceleration from the upgrades.
You're correct that the vehicle that is being modeled is not as "accurate" because those changes to balance are not being reflected and I agree 100% that this makes the physics of
tuning less accurate.
The main reason I don't care too much about this is because the values they assign would be arbitrary. I know I can install a chassis reinforcement upgrade without increasing body roll, which isn't realistic, but I know if there was increased body roll, it would be from an arbitrary amount of weight (probably at an arbitrary height) and may apply just as much weight to a small Suzuki Cappuccino as it would to a Honda Odyssey minivan without respect to interior size or anything else.
My point is that the base physics engine is still better than the competitor "games" (in my opinion) and that what
is being modeled is still being modeled well, the issue is just that those changes you're looking for aren't being made to the
vehicle data. If PD decided to make the chassis reinforcement have mass and have that mass located in a certain position, that would be included in the physics.
The physics engine determines how the data behaves, but if PD chooses to not give data to certain things, it can't be modeled at all. Gotta have a good foundation though, which I think GT5 has.
Again though, I do agree, I'd obviously prefer for something to be present than not, but I want it done correctly. Having flat or proportional values for everything regardless of vehicle is just a shortcut and doesn't make things more "realistic" to me and certainly not more accurate.
Excuse me if I seemed pissed at you as I am not. I am just annoyed in general with the excuse of realism in regards to GT considering how unrealistic certain things are. If the tuning is already unrealistic, why would it matter if reversing certain things that you can't in real life was included.
No worries, trust me I'm right there with you. Short of having a car permanently wrecked or killing off my character in the game, I'm not sure that I could have it be too realistic for me. They do make some random decisions for how to apply "realism" in the game. If it didn't cost so damn much I'd love to sign up for iRacing but I can't see that happening at $99/year.
