Official General AI Comments & Discussion Topic

The sticky AI (magnet effect) is my biggest gripe about AMS2 probably and I've never seen it talked about by anyone from Reiza, I hope it doesnt mean its considered an unimportant issue.

 

I highly doubt that's the case, probably just an issue that's difficult to solve.

 

As usual, we are getting opposite feedback from the same update. I just ran a full race weekend on Max aggression as a test and the AI are still well-behaved to the point it is almost the opposite problem--they are too polite when you come from behind them or are beside them. This was Copa Classics B.

The series I ran is relatively slow cars that can handle a bit of fender or bumper rubbing. If you are going to report AI issues, you need to include the details of what series, track, and all relevant settings. It is possible that a particular series doesn't like new global settings or it's series-specific settings are out-of-whack. The top racing classes in the world, that only a small number of people can competently handle at full pace, are more likely to feel overwhelming if you are even the tiniest bit slower or less familiar than the well-informed and skilled robots.

There is no global/universal issue that the AI are too aggressive if their strength is set appropriately close to your own. The AI will seem overly-aggressive when they are noticeably faster than you because that's what any faster car feels like--human or AI and you are swarmed by vehicles trying to get past you, the moving chicane, as quickly as possible. They will also seem overly aggressive when you do not know the track layout inside and out, because they don't brake earlier than necessary as they are learning the track. They already know the track from moment one, so just like an online race with humans that are not all at the same level, every braking point becomes a collision zone.

 

I had Problems with LMDH and GT1 at Sebring, the AI constantly pitted me out of the hairpin, on the other side the slower classes in multiclass races behave pretty great lately, not getting in the way.
What you said makes sense, I had far less trouble with LMDH at Goiânia for example.

 

Agree! 95% of the collisions I have with the AI are on the first corners at the race start and it's always a 70/30 split my fault because I get desperate and don't do a proper job. In wheel to wheel scenarios its very rare for the AI to hit me.

Between themselves it's another matter, depending on the class and track they are pretty bad, but against me it's very, very good.

 

It would definitely help if people were able to record videos and show examples of how an AI incident happened to them, or what the AI did that does not seem correct. I made this video showing that AI has a tendency to spin on their own when following the car ahead too closely on corner entry, as it is NOT a part of their "AI mistakes" routine, but as a AI bug because when i recorded this the AI mistakes were set to "OFF". I recorded this before the last hotfix and it is still happening with every car on every track.

 

Are you using any custom AI?

What are your AI settings?

And when you say every car on every track, do you mean in that series or every series in the game? Because there are lots of series that do not behave this way. It looks like an issue with the braking or aero on those F-Retros and possibly also an issue with that track layout.

You don't have to make and post videos for every example, but please clarify which other series and tracks the behaviour as seen in this video is happening at.

P.S., I just ran an F-Retro G1 class race at Max Aggression at the same track and saw no incidences of the type in the video. Stock game only.

 

Its a huge deal in the IMSA settings…
No custom AI here just selecting a GT3 or LMP2 and f.x. Sebring and watch the AI get speed boosted without being behind someone or take a corner where there is no space because you are 0.5m from the apex

And thats AI Aggression set to low, medium, high or max

After 1.6 the AI feels way dumber because they are still on the old physics model

 

No cstuom AI.
ANY car class, like try F-Classic Gen 4 at Silverstone 91 and watch this exact thing happen coming into Stowe and watch how many cars will be drifting and spinning out.

I tried again Interlagos 78 with Retro Gen 1 and lap 1 turn 1 already had cars spinning, then lap 2 and turn 2 had three more cars spinning out. You cannot have a race like this.


This situation happens every time when an AI driver follows another AI or even the player way too closely coming into a corner, they start to wiggle left and right and then spin out.

 

I also have problems with AI that were mentioned earlier (pit maneuver, sticky AI, unsafe rejoining). I was driving Stock Cars 2023 on Buenos Aires No 8 track. AI made a mistake, rejoined unsafely and ruined my race.

I also can't overtake AI when they leave the gap, they ignore that I'm there, drive into me and don't stop doing it (sticky AI).
I'm driving on AI Max aggression setting, that's the setting I have been driving for a long time and I didn't have such issues with AI behavior.

 

That doesn't happen with all cars on all tracks, it's mostly the older formula cars on medium and high speed corners when trying to overtake each other, It's more severe the higher their fuel load. I did report this issue a couple of times on the beta, it's as if they all want to do some Scandinavian flicks. It's a pretty annoying issue, let's hope it gets fixed.

 

I saw none of that behaviour when I ran the test race mentioned above. Is it possible my race was too short for them to do a full fuel load and that makes the difference? If so, as expected, a minor adjustment to the AI physics for that/the affected series should cure the problem.

Suggesting these issues are universal and affect all series is not helpful for any readers of this thread, nor to Reiza devs.

 

Yeah, I was able to replicate the issue. I have a feeling it's a full fuel related issue. But I'm not sure.

 

Hello everybody, I'm new here so sorry if that subject was already talked about;
The game is quiet perfect but i noticed in GT3 and LMDH on every circuit, that AI is too fast at first lap because it seems AI is not affected by cold brakes and tyres or not enough unfortunately so it's quiet impossible to match AI at start and first corners/.. after first lap, all becomes ok because our brakes and tyres are more hot..
It seems not so difficult to correct, i don't understand why this is still in V1.6 because else of this AI is quiet good even if a little bit too much aggressive in my opinion.

 

The AIs at the modern version of Imola are too aggressive and too fast at one section of the track. I have mostly noticed this with the GT3 and GT4 categories but not so much with GTEs. I can only match the AIs by a slightest in sector 1 & 3. But in sector 2 I get swollowed. The AIs tend to handle way better through corners Piratella and Acque Minerali. And speaking of S2 times, with GT3s I can make 35.8xx whilest AI mostly sit with either 35.5xx or somehow a 35.0xx! It also feels like this even on skill level 100.

 

When the AI go for each others cars, as they seem to scan their way by ramming cars in front/beside them, they do not try to get out of this situation by steering away from opponent, but try to force their way through other car aggressively by steering into them even more.

 

Yes, the devs could have given aquaplaning to the AI's physics instead of completely removing the puddles.
AI also still is way too fast in rain on slicks, can stay out forever with it's magic unrealistic grip and often refuses to pit on a totally soaked track, driving like on rails. Races with changing weather conditions are senseless that way, as the AI has more grip on slicks in rain as the player on wets. So, the weather options are a nice feature, but completely useless when racing the AI.
This needs to be fixed. But as the game is out for 5 years now and nothing has been done about that issue, I guess it will never happen.

 

It MUST be fixed since there will be the career mode otherwise it will be rendered unplayable. Surely they are hard at work making sure everything will be as tweaked as can get because how else would it be possible to play that once it comes out .
