James Baldwin comments on the McLaren 720S GT3 Evo in AMS2 1.6

Does this hold true in-game ? And if so, where can we find a reliable source of information about the appropriate pressure expected for each and every tire the game models ?

 

They are somewhere in the game files. I know a person was making a tool to get the data, but has stopped. I have no idea when they will start again

 

We can all argue that the game is perfect and his take is all wrong. Until last week's patch though, the description about TC was the wrong way, which finally got fixed after I raised the bug on this very forum... For how long was it wrong ? I mean I just bought the game recently, I have no idea... So it seems to me his opinion is just getting discredited because it is contrary to the narrative folks want to push, by insuring the correct message is reflected in an echo chamber. That closed state of mind usually do not lead to a good ending.

 

That would be very helpful to gather or be communicated by the devs, to help folks figure out proper setups... Why is it such a dark kept secret ? In this case how should anyone even know the pressure is wrong according to what the game expect ?

 

I think the thread has already explained why at some length.

Perhaps the thing is though is that if someone has a reasonably large audience on a different medium the problem becomes that the audience start posting those opinions and having the discussion for the person in the video. Not just once either, and it's not a discussion with the video creator about his views or opinions it's a discussion about the video and its creator.

You saying "He's 2 seconds faster than me..." is not a discussion about what he said, nor is him being a driver, sim racer, acrobat or elephant hunter at all relevant to whether his test was good or bad or whether his opinions are correct or useful or not. With obviously the note that if his opinions are going to be useful in terms of improving this game well that's up to Reiza to decide - they can watch the video.

But, you're not him and he's not here. I don't think people who create youtube videos want a discussion. They want an audience. To that end we did him a favour. We watched the video - he'll get some money - maybe to pay towards driving in GT3 or paying for iracing subscription - whatever he wants to do with it. That, I imagine, is his sole motivation for creating the video.

All I'd suggest though is that many people here and on youtube comments have said reasons why they think the test isn't that great you both acknowledge some of the flaws pointed out and then tell us his opinion is greater than anyone else's because he drove a lap faster than you did.

But, you know Usain Bolt runs faster than everyone else. He doesn't know anything about physics.

 

No one does this. The opposite is true. Rather than listen to what people say you repeatedly accuse the forum, in a rather insulting way of some agenda. e.g saying the forum has "cultists" or, here you're suggesting people have "argued the game is perfect" - which couldn't be further from the truth.

All someone just said was that this test wasn't very good - and it wasn't - but that had been discussed, the points made - and you dragged it up again - it's still flawed and flawed in exactly the same way it was when these posts were made the first time and you read them.

He gave goods reasons but you misrepresented what he said by replying saying "We can all argue that the game is perfect and his take is all wrong" and "So it seems to me his opinion is just getting discredited because it is contrary to the narrative folks want to push, by insuring the correct message is reflected in an echo chamber" which, again, is completely misrepresenting what kuku just said.

Edit: Oh and the reason the TC being 0 when it's off and 10 full was wrong in the description for so long is simply because no one really cared. It is just obvious that the TC was off when it's on 0/10 and full when its 10/10. That wouldn't confuse anyone.

 

Gave this a try with the Mclaren GT3 at Barcelona and reduced the clutches from the default 6 down to 2, and it made a noticeable improvement on how it drives for me.

It made the car more stable on throttle on corner exits, particularly slower corners, and the FBB itself feels a bit "tighter". My lap times improved by almost a second so I went from slow to not-as-slow. Progress!

This does make me curious what would be the equivalent number of clutches that are being simulated on ACC since reducing the clutches from 6 to 2 made the AMS2 car a bit closer to what I'm used to in ACC.

 

IMO the issue is the encryption of the files

 

There are hundreds of combinations in the game, not including how weather may or may not effect said combinations, that's why. There have been a few community efforts to try to do exactly this and they haven't really gone anywhere substantial for that very reason.

How would people know? Through experimenting and asking people who are more knowledgeable about the subject. It's really that simple, just ask about tips for setups in AMS 2 and there will be plenty of folks happy to answer.

 

Maybe not fully this, but I’ve tried to find the regulations on this. I can’t find anything and the regulations I find on LSDs are very vague. I hope someone who knows stuff can help

 

So we are saying here it is just a gut feeling based on what one person figured out through trial and error designing the setup ? After 4 years of experience with this game we should have been to clearly have a list of value somewhere for at leats the most used series in this game, variable condition do not matter as all you need is just have an agreed set base to work from.

If that is not established yet, so how can one say that pressure used on James setup were all wrong where they could have been just optimal for that setup and track condition is blowing my mind...

 

We have the knowledge of how to setup the pressure correctly using temps. If someone uses the same setup they can say if anything is wrong

 

I never argued anything of his views .
I’m on record in Beta circles as saying i think there’s a little too much free rotation on coastingwith default setup, but it’s subjective to how you drive and how you change the setup.

But a big part of his video was talking about the car slowing down to much off throttle… but he was running a setup with maximum engine braking, he might as well have been towing a boat anchor. , so off course he’s going to feel it that way .
But that’s not anyone’s fault but his , and shows how much his views were skewed by his choices and not something that can be attributed to the way Reiza have implemented the car model .
You don’t access a car off a car sales lot by immediately hitching a boat to the back and then complain about its negative effects on the car .

 

Alright so we are getting somewhere then : 720S GT3 Evo @ Ambient 27C Track 38C have to be around 2.0 bar. I can assume the same is true for all GT3s gen 2 right ? Yes, it will depend on a lot of parameters in the setup and track condition (don't need a further lecture on real world physics), but the ballpark should be there, especially if 2.2-2.3 can be judge to high. If a .3 difference is noticeable enough then it should not be hard to give a target to aim for for each and every tire modelled in the game.

I guess as a chrismas present it can enlighten the whole community to get further details, as you can see here lots of folks are just guestimating and left in the dark.

So here are my further question, assuming the same conditions :

• What pressure should be used on LMDh ? Should it also be 2.0 or is it a different Pilot Sport model ?
• Is it also the same for the LMP2 gen 2 ?
• What pressure should be used for GT3s gen1 ? As you know they use Pirelli tires which are usually optimal between 1.8 and 1.9, is this correct ?
• What about GT4s are they using pre-2019 GT4s specification tire model or the latest iteration of the Pirelli tires ?
• In regards to GT1 class they use a mix of Michelin and Bridgestone, what pressure do we expect to use for those ? Should we aim 2.0 for the front and 1.8 for the rear regardless of the brand ?
• For group A, we are again looking at a mixture of brand would both the Dunlop and Michelin tires fall into the window of 2.2-2.4 that was used back in '92 ?
• Final question for Stock Car post 2023, Hankook tire usually run higher pressure, is it also the case in-game and should we aim for 2.4 ?

I won't ask this for formula cars yet, as it requires even more details as you expect way more difference front to rear. If it helps you keep stuff in the right place, feel free to use a pinned thread to reply to this, that would definitely bring some helps for anyone starting out with the game. It does not help to not share such basic information and leave it to dataminers to figure out, it only leaves new comers struggling and providing incorrect feedback about the game physics, potentially bashing it for the wrong reasons, when just telling what pressure to target can resolve already 50% of the problem.

 

I think that there is no "target pressure" like in ACC (26,8 PSI) in AMS 2. As I understand it temperature is farmor important.
In ACC you have to increase pressure to get more temperature. In every other sim I played (including AC [1]) it's the other way round. Ans as I also understand it's not an ideal pressure or temperature but - as I wrote - a operational window.

Honest question: Have you gotten your tyre pressure values from real data?

 

By design and by countless hours of work by devs , you will find that Default setup pressure is set in a way that it will end up pretty close to optimal after a few laps on a moderate temp track .
higher temp tracks and heavy loaded on one side might get over pressure and vice versa.

So it’s not that hard to work out if you just start with default and get the best performance you can out of that before you start fiddling.
for example If 3 of the tires are close to 2.0 bar and the loaded tyre is 2.1 and getting hot , you have a pretty good idea what the target is don’t you. Generally you will find starting cold pressure between 2-3 bar lower than optimal.

I always do my TT hot lapping with default set up until i’ve got to a point i can 100% say i’ve peaked and then i often leave it there as then there’s no way i can improve until make some adjustments. then if i am preparing for a planed race i will set conditions in test or offline race that will be representative and make further race specific changes to pressure and cooling there.

 

Don't get me wrong, I know we are talking about operational window, but this can still be precisely defined for a stable pre-defined track condition. The issue the game is starting to face and will only get worse as involvement with LFM increase is : competitive people. They will look for everything to get an edge over the others. Currently it is very difficult to get any sort of officially supported/sponsored setups for AMS2 and you have 3 options :

• Ask online for help.
• Instruct yourself and figure stuff out.
• Download TT setups.

I let you guess which option is most likely going to be the favored one and what the result will be.

Just be ready to end up with more and more of this type of content :

They just poped up in my feed in the past week and peeked my interest in understanding more of the game engine, espescially its limits. Not all players will be willing to go through the process I am in currently. They will just trash the game, which is a shame because, as I already stated I believe it is very good and fun. I already had this exact same discussion with Nils and he mentioned the struggle he had to get any kind of info of the ins and out of the game, I understand why now...

And yes, I worked for a tire gauge manufacturer, so we had access to some data, including for historic cars, specifically for supporting events. Alternatively, with some googling you can also find out info.

 

You’re missing the point that there is no magic set up . the track conditions are variable and you have to make adjustments based on them or drive in a manner that doesn’t expose a stressed tire that’s not happily inside it’s window .

You need to approach it like you would IRL . Run - collect data - make adjustments- Run again .- evaluate and repeat.

Real life teams don’t go off to the local tuning store and buy a setup.
