No, that is just the easiest way to visualise it, because you can park the car and do something else for 15 minutes.

As mentioned elsewhere in this thread, you can also do a lap or two of Special Stage Route X in a road car and you'll notice the same thing happen.

But it can happen in any track/car/tyre combination where (for whatever reason) there is not enough energy going through the tyre/s to keep them in their ideal operating temperature.
Gotcha, well that’s something I guess. Still, a mind boggling, wasted effort as the fact that’s it’s incredibly unrealistic and useless stands. I’ve never once seen it blue in an actual race anywhere under any conditions in over 500 hours of playing since day 1. I’m not one to let my car sit idle on the track for 10-15 mid race though. If it were at all useful it would likely be blue for the beginning of first lap where you have noticeably reduced grip and really should be blue for at least a bit when getting fresh tires, especially after a pit stop on a wet track.
I’m not saying they don’t turn blue at SSRX, but I tried 3 different cars on 3 different tires and with 3 different tire wear settings at SSRX and never once did any turn blue down either straight, not even the open wheel SF19 where the tires are completely exposed to air.

I suppose in theory tyres will very rarely be cold enough to be blue - unless you're sitting there for a while as even moderate street driving warms tyres pretty quickly
 
I'm amazed that PD put that tiny, almost invisible border around the tyre. The app functionality is what I would expect to be in the game.

A chap on YouTube did drag times on SSRX using the app and a variety of pre-warmed tyre temps, and saw little to no difference in grip. This was a few updates ago however.

There was some discussion on whether tyre wear would need to be enabled to trigger parts of the tyre model.

I think it's definitely surface temp shown in the app. Explains why one burnout quickly cools back down as heat conducts away into the bulk. But after several laps the thermal mass of the tyre holds the temps steady.
 
It does, didn't you ever see your fronts turn red around the perimeter when locking the brakes? Turn off ABS once to test quickly.
It doesn't tell me my tires are cold unless I park the car for 15 minutes. Not exactly useful when you now start on "cold" tires that take a few laps to warm up.

If my tires are cold enough to affect performance after the new update, then the tire UI element should also be updated to display that properly. I shouldn't need a thirdparty telemetry app.
 
In Sport the tires themselves were blue when they were cold if I recall correctly. Not outlines. I could see them bringing that back. Usually took half a lap to warm up.

Tires overheating in GT happens too quick and they "Cool Down" too quick as well.
If you warm up the tires properly it takes several minutes for the tires to cool down. See my previous post about the Ferrari VGT with a tire temperature display on the steering wheel.

But do a burn out, and the HUD shows them red for a second then they go white again in 2seconds.
 
I think that would be white outline means hot. red means super too hot.
The ferrari appears to show all the variances of within the white range.
the red indicator is pretty useless, its not really telling you the tyres are getting warm its saying there is an emergency event occuring! As soon as that emergency is over the red goes to white, meaning the tyres are "normal" hot.
 
Looks like the blue starts at ~35C, red at 135C.... Making optimal 85C?

Comfort and racing tyres both show the same colour behaviour, in real life I'd expect the race slicks to want a higher temp.
 
maybe that's why all the races have a rolling start...
No, Rolling start is because PD cant code an AI to save its own life.
The AI are too "Scripted"
They cant anticipate weather, they enter pits after the track is wet and this wetness has to be at a certain threshold as well.

Makes we wonder how the AI are coded when doing Custom Races. They work fine in my races.

You need to pay more attention to them.
The AI don't even acknowledge your existence.
You can be on the racing line and they will just bump you off or spin you out.
If it rains and one of the AI gets caught out and remains on slicks, you will get the AI Train where they wont overtake as that means getting of the "RACING LINE"

I know all about being bumped off, due to being on the racing line. Posted plenty of those. How are they, in your races, with grid starts?
I can do a grid start now and post how they drive fine.
The thought you quoted was, rolling starts are probably programmed because maybe that’s a way to warm tyres. AI have all aids on. I don’t use TCS. So, with Grid Starts, I’ll 99% of the time, lose a couple positions to the AI, in my races. AI don’t seem too effected by cold tyres on grid starts to T1.
How AI behave during the race, due to however it starts, is a different matter.

When I have encountered grid starts the AI has been slow.
Grid starts bunch all the cars together, which leads to easy passing.

Rolling starts are done because it gives you a challenge of "Chase the Rabbit" that has done 500m down the track.
Each car has a 20m gap.
20mx19 cars is 380m + the 20m you have to gain on the car in 19th so 400m.

It is the same reason on why we don't have qualifying.
It would be all too easy for you to get 1st.

About the difference of having to chase 10 meter or 500 meters, yes of course, 500 meters is more difficult than leading the race with no challenge from the first second.
We all also know the AI is pretty bad for many reasons, it shows ingame very often.
Then you would prefer a game that is "pole position simulator" against a game that is "AI overtake simulator"?
The 2nd at least is a bit of racing, the first could just remove all AI cars altogether. ;)

Because that's the only two ways that AI can be programmed in a racing game...
 
I played games in the 90's that modelled tyre temps
Someone beat me to it...GT1 and possibly Sega Touring Car.
So what LeftoverPizza is trying to say is we had more powerful hardware than we do today. 🤔
Maybe not today but there have been plenty of times that the most powerful hardware of one generation has been beaten by lesser hardware and a few cases where previous gen hardware has been crazy powerful but failed in the marketplace. 3DO, M2, and the 32X fall into that category. They all looked better on paper than the PS1 and even the Saturn did. The only one of those that was to compete directly with the Saturn and PS1 was the M2. It was never released as a console.
To a lesser extent the RDI Halcyon and the Pioneer LaserActive were...crazy graphics with gameplay on par with the Genesis or Saturn. The Halcyon was never released, leaving the LaserActive to be the physically largest home console ever sold (It dwarfs the PS5). Around 10,000 were sold, and I'm one of the lucky owners. The graphics are impressive, easily outdoing the Genesis and SNES counterparts.
No, its not a factor.
The OS has basically no effect on the hardware performance a gaming console can pull when a game is started.
This was even more true back on the old consoles that barely had any kind of "OS" but simply a boot up sequence right into a game.
This is a bit less true with todays consoles that try to provide some kind of multitasking, but the PS5 definitly sets priority to the game currently running over anything in the background (which tends to sometimes react rather slow).
I have a few of those like the 2600. The 7800 has a rudimentary BIOS as does the N64.
Would it be a stretch to suggest kaz does not AT ALL care about how much of a "racing simulation" GT7 is?
No Gran Turismo that I've played has claimed to be a true to life racing sim, but they are less arcade and more sim. That line is just a slogan.

I can check both of my copies of Sega Touring Car Championship (one US, one JP) when I get home, but I'm 99% sure it doesn't model tire temperature, and if it does, it doesn't display it anywhere. Maybe the arcade Model 2 version did, but I've never even seen one of those in person (and I spent a lot of time in the 90s in arcades).

The 32X absolutely did not outdo the PS1 or Saturn on paper or in reality. It was just an add on for the Genesis/MegaDrive, it had lower specs all around. I know, I owned both (and still own two Saturns).

I'd also bet good money that the 3D0 didn't outspec the PS1 or Saturn either; M2 sure, but as you said it was cancelled before release. But if it was marketed like the 3D0 it probably would have failed too.

"Offline" - Anything outside of Spot & Lobby act very different from "Online". My observation was made in a Lobby I had open for GTWS open practice. "Online".
 
For the first time ever I personally witnessed the tire temp indicator turn blue while playing today! I didn’t even have to let the car sit idle forever. I was going back and golding some missions I only had silver on and the mission where you have to drive the Veyron over 5 miles on 1% of gas the indicator turns blue.
