As an A+ ranked driver with countless hours and years across multiple Gran Turismo titles, I’ve reached a troubling conclusion that I need to share.
I’ve been racing in Gran Turismo games for years, working my way up through the ranks to achieve A+ driver rating in both GT7 and Sport. I’ve competed at GT1 level of World Series, putting in thousands of hours perfecting my craft across multiple GT titles. This isn’t coming from a casual player frustrated with losing – this comes from someone who has lived and breathed this series since its inception.

Recently, I’ve begun to suspect that GT7 may be employing retention manipulation tactics during online races. These are common practice tactics that big game developers use and in my opinion deceptive. What I’m experiencing feels like deliberate performance handicapping designed to create artificially close racing, particularly when competing against slower-rated drivers. I’ll use this weeks deed forest as an example. I’m mid 1:26s as a qualifying time but because of my region and Rank there are not many players with this pace or Dr rank to compete with. In races it is somehow impossible to achieve writhing 0.800 of my qualification time despite driving the car extremely fast and pushing obviously at the correct time when tyres are as good as new and with low fuel.

Why I think this is accruing is because of what I stated previously. Here are my suspicions as to why.
The symptoms I’m noticing include:
• Cars not performing as they should in specific races
• Sudden, unexplainable loss of grip at crucial moments
• Performance inconsistencies that don’t align with car setup or driving conditions
• These issues seeming to occur more frequently when racing against lower-rated opponents

While I’m not entirely certain about the technical methods that could be used to slow down faster drivers, the pattern is becoming too consistent to ignore. Whether it’s through subtle physics manipulation, grip reduction, or other behind-the-scenes adjustments, something feels fundamentally wrong. If my suspicions are correct, the implications extend far beyond just frustrating individual races.
If the game is artificially manipulating race outcomes, then our Driver Rating (DR) system becomes meaningless. DR should reflect genuine driving skill and consistency, not the result of algorithmic interference designed to create “exciting” close racing.

This has serious consequences for World Series qualification. These events are supposed to represent the pinnacle of GT competition, where the fastest and most skilled drivers compete. If DR ratings are being artificially manipulated, then:
• Deserving drivers might be prevented from qualifying
• The competitive integrity of the entire World Series is compromised
• Players are being denied opportunities they’ve legitimately earned

If Polyphony Digital is indeed implementing such systems:
• They have a responsibility to be transparent about it
• Players deserve to know if their race results are being manipulated
• The competitive integrity of their esports platform is at stake

Gran Turismo has positioned itself as “The Real Driving Simulator” and has built a serious esports ecosystem around that premise. If retention manipulation is occurring, it fundamentally undermines everything the series claims to represent.
As competitors, we need to know that our results reflect our actual performance, not algorithmic decisions designed to keep us engaged. The World Series and the broader GT community deserve better than artificial drama created at the expense of competitive integrity.

I’m sharing this not to be destructive, but because I love this series and want to see it maintain the competitive integrity it promises. If I’m wrong, I’d welcome clarification from Polyphony Digital. If I’m right, then we need to have an honest conversation about what this means for the future of competitive Gran Turismo.
Has anyone else experienced similar issues? I’d love to hear from other high-level players about whether they’ve noticed these patterns too.

It'd be weirder if you were getting close to your qualifying time.

Qualifying for Daily Races is done in a controlled state where the car has no tyre wear, zero fuel weight, and optimum tyre temperatures. The races have tyre wear, have tyre temperatures, but most importantly start you on a full 100kg fuel tank, and they never use big fuel multipliers so you don't even use a quarter of that in your average daily. There hasn't been a daily race in well over a year where you run to even less than half of your fuel tank.

They used to do a specific race template that was a fuel saver and you had to choose between pitting or not, but they never got the balance right, no-stopping on the harder tyres with big fuel saving was always the correct play, and they stopped runing that template because it was no fun. Since then? Very lean fuel usage.

That's all it is fuel weight, with some non-optimum tyre conditions.

I'm not sold personally. I'm a B ranked driver who has raced Ds and Es and wiped the floor with some. Yes some of the races have custom slipstream but that's in full view on the race settings page. And as Nakano said quali is a different beast to race, I can say for certainty I've felt that difference.
 
And DR points are exposed (if you know where to look) and can be clearly seen as a straight exchange from drivers behind to drivers ahead, as a proportion of the difference between them to the formula that's been known since 2017.
 
Interesting observations. What concerns me more is PD blatantly lying about the slipstream being classed as 'disabled' when it obviously isn't. Also, why no exhibition series for manu or nations.

Must all our heads be turned in the direction of the world tour, where we know PD have invested a shed load of money and resources. So much so, that they don't want anyone to be distracted by a championship for us mere mortals.

I've come to the stage where I'm boycotting watching the world tour. It does nothing for me personally. Why should I give it my views when I get nothing back in return content wise?

I have nothing against the drivers who have earned their place amongst the best in the world. More power to them. But I won't be watching.

The whole.format is just a glorified holiday, while the rest of 99.9% of the GT community are thrown scraps of content and zero championships. While we wait for best of the best to finish what they're doing. I'm an OG player from 1998. I've got better things to do with my time and life, if PD aren't providing a minimum in competitive Esports for me to enjoy.

For the first time in 25 years I'm lookimg forward to the release of another racing title, that isn't GT related. And that game is Project Motor Racing. If PD is trying to alienate its long term player base. Then they're doing a great job!

Congratulations!

 - In the race details of Daily Races, Slip Stream Strength is displayed as Disabled even though a strength is set in the event regulations.

Where is your proof? Evidence that PD is doing what you are suggesting?
Unless you have this proof / evidence then all you are doing is stirring the bog.
 
Sounds convenient... My.proof is in the statement 'slipstream disabled' when its obviously not. What more information do you want me to provide? How am I 'stirring the bog' when I'm simply stating a fact?

I'm not sure why you're asking me that, or putting scare quotes into something I didn't say - but somebody else did, and it wasn't even addressed to you. 🤷‍♂️

You replied to the wrong post, it was stating to the OP he should have proof before stating that PD is manipulating.
I was not even replying to your post as @Famine ,in his reply, noted that PD admitted the slipstream issue.
 
If you say so mate...
I don't really know what part this is a reply to, but the first part is Mikail Hizal - the world champion guy who sort-of works for PD - publicly noting that there's a bug, and PD subsequently acknowledging that there's a bug, thus not "blatantly lying".

As for the second part:

Aaaaaaanyway, back to the conjecture of the first post we go.

The OP won't find specific evidence. Which he himself has stated. He's simply making an observation based on his experience with the game as a long term player. None of us have access to files to do with slipstream or specific race data. So he won't be able to prove his observations either way. I just happen to think he makes some interetsing points either way.

I understand your point. However I have had multiple races on this game and I am more than capable of achieving within 0.300 easily as a consistent race pace essentially from lap 2 after the tyres heat up and drop roughly 1 second when the tyres fall below half worn. And have matched if not beaten my qualifying time in a race on multiple occasions.

What you’re saying does carry a percentage of weight however it’s not a real world 100% fact. It has only been since the last update that I have noticed these weird physics and lack of power and grip far more frequently. To be 1 to 1.5 seconds slower than what I’m able to achieve is very far fetched to me based on all my previous experience.

Video game developers do implement retention based algorithms in there game it’s not only used as a form of skill based control in other titles but also to keep you playing to achieve specific goals or achievements in game. (I.e lap time). This is a practice that has been used more and more frequently in big titled games. And I feel has no place in this game. I have experienced this type of programming, many, many times before and have a very good understanding of what it feels like and looks like based on the games main objectives. This is not some fictional idea Iv drummed up this is a real game development design and has been attempted to be patient by many publishing companies. It’s also use in certain apps and on some websites. My question is is it in this game?
 
The question still remains. It’s an important question. I think everyone deserves to know the answer and proof that it is or isn’t being used. It’s a critical point in the games life cycle with the inevitable release of a new instalment with GT8, keeping player engagement is a crucial aspect. You only need to look at the games ticket roulette system. The exorbitant cost of specific cars with the chances of obtaining the required amount of money in game is made incredibly difficult to push players toward in game credits purchasing. I’m more inclined to lean towards the developers carrying out what they see fit for the company not the players. The two mentioned examples of roulette tickets having odds that are on the extreme end in their favour coupled with car costs leaning towards pushing players towards purchasing credits. And also the real world cost for in game credits again is rather high leaning me to believe the mentality of them worrying about there bottom line not the players.
 
How is it in their favour? You win every time and you don't place any bets.
Honestly if you don’t understand the topic of the post please don’t post a reply. If you’re not able to understand what is written in the post it’s best not comment. You only make yourself look stupid. To even have to explain it to you feels like a waist of time.
 
If you want people to take you seriously, you'll have to bring some evidence forward beyond "I'm good and I know what I'm talking about". With respect, we don't know you from Adam.

From my own totally anecdotal experience, it seems highly unlikely. Sport races have a natural flow that doesn't feel anything like the rubberbanding we get elsewhere. Besides, GT7 is 3.5 years old and popular; with the number of people who play Sport, the amount of content on YT, and the calibre of drivers who participate in major events, something like this would have been exposed ages ago.

The simplest explanation is that you're not as consistent as you think you are. No shame in that, very few people are.

Also, "waist of time", sounds like a Douglas Adams novel! :lol:

It is not up to people here to prove you wrong, the burden of the proof is on you.

You come with an affirmation : "Gran Turismo 7 Using Retention Manipulation in Online Racing" and some observations of yours that we can't confirm or replicate.

You need to provide evidences that we can test as @jrbabbitt told you already.

And you should refrain from being dismissive and disrespectful if you really want to make this thread go forward in a constructive manner.
 
You ask me to prove something that requires the access to PD’s code. And reverse engineering it as it is extremely complicated. And also a criminal offence to do so.

I could upload countless videos and breakdown throttle position braking points on comparison laps on the same line. And you will post dismissive comments highlighting any slight bias your brain can conjure up for drama and argumentative purposes. The proof has to come from PD.
As highlighted in my previous post.

it is Not beyond PD to implement systems or algorithms that benefit solely them at the cost of the players experience. The question is to what point do they do this do. You need to have an analytical mind to be able to take into consideration all the factors involved and determine the likelihood of these systems being in the game. Forget the game and think publishers, developers, stakeholders bottom line, profit. The odds of such a system being implemented in this game given common use of it in the digital landscape in multiple other titles is VERY VERY HIGH. I want to know if it is.

Yes, prove the thing you pretend is true.

The method(s) to prove it are entirely up to your choice.

🤣 stop projecting please. You are the dismissive person here, we have plenty of interesting content to read and talk about here and don't need drama or argumentative fight.

You come with a point, give us good evidences or let it go.

That looks like conspiracy theory here, so many ifs, may bes, odds... ☺️ the fact that something is possible, has reasons to be, do not entail it being real, unless being proven and backed by verifiable facts.

Ok people give it a few years and just like other games it will all come out in the trash. **** you people make me sick and are a good reason why the world is so ****ed. Simple people with simple minds.
 
@RINGO2287R
I don’t mean to offend you but I think the problems are on your side, not the game. Looking at older threads and posts you made, I would say you are not that fast and consistent to determine the races are rigged or not. Being an A+ rank driver or not does not mean much nowadays because of the nature of the DR system.
Yes, I do feel that GT7 still contains numerous issues in its game designs, especially the e-sport portion has flaws which I also don’t like and play much but I hardly agree with the points you made.
You definitely should upload some videos that may convince others before keep arguing.
 
Retention manipulation in online racing?

Yes they definitely are.

After 6 races they'd manipulated my retention all the way down to zero and I never bothered again.
