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?

Convenient that... PD has acknowledged that there is a bug?

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?
