Parity in GT5 or "Is the Mustang GT really a boat?" and other Q's.

[Rudenut]

I am going to start a project attempting to determine the relative performance of cars at the 500 pp tune.

All cars will be run on GVS as I know this track best. I will run them on the seasonal They will all be tuned utilizing the principles that the GTtuner phone app utilizes with similar settings used for each. Adapting to compensate for torque variations (diff will be adjusted as needed). This ,I have found, is a good starting point for tuning.

The purpose of the test is to highlight the disparity of some cars at a particular pp. I know many people here are going to give me the (PP is just a guideline) lecture but it is not necessary. Some cars, I have found, are so exceptional at a PP level while others are quite the opposite.

Cars that are total fail will be alloted more time for tuning in an attempt to improve times. I understand that PP is a rough rating of performance but I feel it should be refined.

Torque, I believe, is one area that the PP system applies too much weight in some cars. Whereas MR configuration is not given enough weight in many cases.

I would like PP to more accurately depict the actual performance of cars. This is not an unreasonable request and I don't want this thread to devolve into the usual "critics pointing out shortfalls in an attempt to improve the state of the game vs fanbois that feel obligated to protect the honor of PD and the "perfection" that GT5 represents" arguement. If this project seems like a waste of time to you rest easy, it's not your time.

Sounds interesting. It'll be most useful if comprehensive, but that might take some time! It should be illuminating enough with only a few examples. Hopefully PD are using the time trial data to see how their PP system fares across different cars, but in the meantime anything we can do to compensate would be useful for closer racing. For example, a standardised test could be used for anyone starting a racing series, which should make handicapping easier (which reminds me; isn't Shem doing something similar? EDIT: here.)

Good luck. 👍

My friend, PP is a metric which is influenced by only 4 factors as we have seen till now:
1) Engine power
2) Torque
3) Weight
4) Aero


On the other side, the track performance of a vehicle depends on these factors above as well as:
1) Suspension (you will tune it)
2) Brakes (unknown to me if any differences between same weighted cars exist in GT5)
3) Dimensions of the vehicle (wheelbase, axles' width difference) that affect the agility
4) Gravity center (height)
5) Balance of weight

All the above don't affect PP measurement.

In conclusion, your test might be an evidence about the objectiveness of physics engine in GT5. For example a Mustang GT 450PP cannot lap the same track close as fast as an RX8 450PP in real world...

Weight distribution does effect PP. Perhaps not as much as it should, but much more than it originally did.



Also note that, in regards to the Mustang GT, the weight distribution is absurdly off from real life, which might be why it is such a pig.

Your example is exactly why I am doing this. The pp system can be altered and improved. The mustang and rx-8 do not really have the same performance and that should be reflected.

I think it is likely I will find some exceptional cars....these can be reflected individually as well. We are talking about adding a couple columns to what amounts to a spreadsheet if it is anything like every other game I have modded/edited.

Weight balance is considered...not nearly enough....should be more a sliding scale.

Weight should also be on a sliding scale. Super light cars are penalized too dramatically.

Engine/drivetrain should be considered.

Torque should be reexamined...

I should add that that list of on track dynamicd can and should be given metrics as well. This is an attempt to highlight just that.

As to the mustang weight balance....I suspected as much. Another symple database change that should be fixed....Lister Storm weight anyone?

My thoughts exactly... 👍


As for the OP This thread sounds like a great idea! Good Luck
