Gran Turismo Sophy: Sony AI x Polyphony Digital

[Mathaios_C]

Honestly the main problem right now is that they are just not aware of you. I get smashed like i was playing gt4. Not comparable at all with the first version. They just do jot use the breaks when are behind you. Like they do not see you on the track. Just played at Nurburgring and first corner is just a nightmare.

I posted a video in the video thread about this exact thing. Extremely frustrating.

I believe that the speedometer thing is just a bug in the replay, because the revbar does not change and the sound of the engine does not change, and there is no sudden jump to a slower speed in the environment. BUT Sophy clearly lifts a bit before the human car sweeps past.

Nah, what the speedometer shows is what I saw happen in front of me. The AI literally jolted to that lower speed way faster than going 80% on the throttle would have. There was clearly something that was triggered there due to me not being past it by that point in the race. This did not happen the previous nor following lap.

It happens on this straight line regardless of the vehicle?
(I can't test right now, my new ps5 arrives on Wednesday)

I only paid attention to this car since it happened directly in front of me so idk. This is the most extreme and obvious case I've seen but it does mirror what usually happens in these races, where the cars up ahead about 50% - 60% through the race will dramatically slow down so I can catch up.

That’s nearly like the Nurburgring programming. When the AI are signalling, if you don’t pass it in a certain time, the AI will speed up again. Sometimes, the AI will be signalling and just as you get to the A-pillar, it’ll accelerate.

Tried racing Sophy with the HiAce on Suzuka and, yikes, what can I say, next time I won't go on Professional!

Maybe Intermediate or even Beginner, 'cause I dunno if She changes her setup when you do to try to trick her and own her with a stronger car but at the start of the race She was slow on the straight then She just bursted with speed when I passed by on Professional mode.

No idea if that's a rubberbanding nightmare mode She gets or if her setup got changed to match mine... or if it's just me who sucks... I'll go with the third! 🤣

Here is my example, now on YouTube. In this case Sophy doesn't lift off, its speed just changes unnaturally.

The same thing happen with the standard IA, PD need to work in this and is really notorious in La Sarthe and Route X

I could be TOTALLY wrong, but this all looks like two systems competing. I see two systems at work in the video above. I see AI and I see GAME rules.

Just by the video evidence, and what we see in game. it appears that there is AI to control the car (as in pilot it around the track), while at the same time, there are game rules governing the pace of the car (the infamous rubber band effect). We can see from the in car view that the AI is not lifting, but the car slows none the less. The AI didn't make a mistake; a game rule was triggered.

Back in GT5, when the AI difficulty was unlocked, increasing the difficulty didn't make the AI better, it changed the field of cars so the AI had faster cars. Even still, in the custom races, the AI never changes, or changes very little. Switching the AI from Beginner to Professional does very little, but changing the cars DOES increase the overall difficulty. Presumably because the difficulty of the event is determined by the game rules, which dictate the gap between you and the other cars.


Could it be that for nearly 30 years, we've been complaining about "The AI" to the point that Sony invested in Sophy AI, but the real problem has been core game rules, controlling the pace of cars, and it has nothing to do with AI behavior at all? Because we have all noticed that the "AI" is so much better in the hot pepper races where the pace is allowed to be more competitive.

I'd bet you a dozen doughnut that this is where the "AI" problem resides
