Plenty of motorsports use rolling starts, so not sure what you're getting at. Actually, I do know what your agenda is.
Agenda? Aren't we both grown adults discussing a videogame? Don't be so silly. I spent a lot of money getting hold of the original Japanese GT1 back before it arrived in the UK, had to mod my PlayStation to play it and even buy a new TV. For a long time Gran Turismo was a big part of MY ACTUAL JOB. This is ResetEra, not GAMEFAQS. Agenda? Man alive.
I'll explain it again for those talking part in the thread that might be interested in the difference between real motorsport rolling starts and the ones that appear in GTS (and other GT games).
In real life rollings starts are essentially like a mobile grid. The cars are all bunched up as they would be in a stationary start. But if you set a custom event in GTS to do this you'll sometimes (not always) get some framerate issues at the beginning of the race.
So the single player events that Polyphony has set up in the game, where you don't control the start method, uses something you rarely see in other games such as Project Cars, Forza, F1 etc.
And this system has the start with all the AI cars strung out in a long procession, sometimes spread out as much as half a lap, so at no point all the AI cars are grouped together as this can cause a frame rate problem. In most racing games the biggest stress on the engine often comes from a grid start.
That's how GTS protects its framerate, through these kinds of odd starts, and by having fewer AI cars on track compared to similar games. Now some people don't mind these "follow the leader" races. But I'm not a fan, never have been going all the way back, because it's not really traditional racing when the front car starts half a lap ahead. So I tend to play GTS in Custom Race mode with "regular" rolling starts and grid starts, because I don't mind a little bit of a frame rate hit right at the beginning of the race, it soon subsides. I wish the regular single player events used these too.
And that's it. No agenda. Just a simple discussion of how one game is optimised.
Edit: I should add GT has done this long procession for much of its life, and it's something many of its players have spoken of over the years. It's not like it's something I've just spotted. Some of us been talking about it for over 20 years!
