I know that GT4 had 500-700 parameters that defined the driving characteristics of the car physics model.

I know that Forza 1 had 9000.

How many does Gran Turismo 5 : Prologue have?

(Can someone also tell me how many Forza 2 has?)


Thanks for the help! :)
 
What is parameters?
And where the people got their numbers from? Link for Sources?
 
Turbo.
Is it better to have a lower or higher number.

I think what it means.. more is better calculations?
Thats why it would be great for him to explain what this thread is all about.
 
Even if someone knows the real number and has a reliable source to back up their information, it doesn't tell us much. A sim could have 100,000 physics parameters and still handle like garbage.

You'll get a much better idea of how realistic the game is by playing it than you ever will from a simple number.
 
Essentially, a parameter is a variable that plays a role in the physics calculation (temperature of left rear tyre, % brakes applied, and so on).

While numbers are fun to look at, as Wolfe said, just because there's more numbers being crunched doesn't necessarily mean they're being crunched realistically. You could make an arcade racer that crunches more numbers than all the racing sims ever made combined, if you were so inclined.

But to be fair, as both Forza and GT are sims for the most part, it would be interesting to compare how many paramaters each game is actually calculating. At the end of the day though, one sim may technically be taking more parameters into consideration, but if it's various paramaters affect the physics model in an abstract way and not as they would in real life, it could still wind up feeling like a less realistic sim.
 
I was joking.This guy is fantastic.I love the thread.I don't know how many physics parameters and ıt's none of my business..Why he wonders that? What he gonna do with dis.There is no source sorry haha

then you've made yourself look a muppet haven't you. whats the point in wasting peoples time.

If there was ever a case for closing a thread, this is it.
 
Yes I am muppet. you watching me on Sundays? Oh ok sorry.Don't get me wrong but I have a question for you,If you are GT fanatic then you'll know it..
The question is 'How many does Gran Turismo 5 : Prologue have?''

GT_Fanatic waiting for your answer.

Is it me or does this make NO SENSE at all??? What are you trying to prove?
 
I'm not trying to prove anything.Why don't you looking this guy's post about me?
 
OK everyone start calming down or I will start to hand out some calming 'measures'.

Now in regard to the thread topic.

The simple answer is that currently we don't know, PD have not yet (to my knowledge) stated how many parameters are being used in GT5:P, we do know that GT4 used around 500 - 700 so that could be used as a starting point.

However as Wolfe correctly pointed out, the number alone is only half the story. How quickly they are calculated and updated, and how well the numbers themselves are used are just as important.

You can collect all the numbers you want, but unless they are used correctly they are pointless. Take the Race Driver or Colin McRae series as examples; they are without a doubt using a good number of physics parameters. All of which is ruined (for a sim) by the use of a fixed centre rotation point on the cars; cars do rotate (yaw) but not around a fixed point, rather around the centre of gravity, which moves as load transfers. So this one thing throws out almost all of the parameters used, as it uses them incorrectly.

You will always be able to tell more about how good a sim is from driving it, numbers alone will not tell you the whole story.

That is correct.

Also the other thing is, where did the original poster get the GT4 or Forza numbers? I don't recall ever reading a number for that, and even if a developer (be it for GT or Forza) said something in an interview, he may well be making it up.

refer to my previous post to you. Enough said.

I got them from wikipedia! lol

Interesting perhaps, but as you yourself acknowledge not particularly useful.
