Official General AI Comments & Discussion Topic

Hello mate! Thank you for reply. I will try my best to record a video with things I mention above. (Just usually done make any video) . As soon as, I will upload to dedicated thread and tag you, ok? Thank you!

 

After latest update, AI still simply cuts corners when being overtaken before curve instead of breaking for the corner.
And of course, still no penalties for AI.

 

Thank you for taking the time to help.
Well the difficulty level is always gonna be dependant on the skill level of the user otherwise what's the point??

And i do qualifying starting at 4th just 2 tenths of first. So I would fairly assume the difficulty level is more or less on point to skill rather than it being far too easy/difficult. And as for the mistake level, it's a sweet spot between a couple of cars logically making mistakes and too many cars making mistakes or bringing out FCY too often. But I wouldn't imagine it makes any difference in how the car just basically softly rear ends you in long beach.

And as for aggression, I do appreciate your time to suggest alternatives and solutions, but the aggression is set to what the game itself suggests for high downforce/open wheel cars.

As I love the game I feel it's worth the time to point out these issues on a rather popular track when it comes to emulating IndyCar.

 

Which vehicle class, track, and corner did this happen at?
Based on the changelogs, AI behavior changes a lot depending on the vehicle class, track, weather, and time, so having those specific conditions can make a big difference. Without those details, it's really hard for the devs to reproduce the issue, and it might get buried under other tasks. If you could share those conditions (or even a replay video), it would help a lot in getting this properly discussed and fixed!

 

Is there some back end rubber banding in this game? spending Hours building custom Ai files only for the top 2 to be separated by less than a second after 60 minutes of racing every race. Mansell in a williams at 99skill should be killing Patrese in a williams at 89 skill but they end up glued together more often than not.

 

I’ve been a big critic of the AI over the years, but I genuinely think it’s taken big steps in the right direction. I mostly race modern multiclass endurance, and the AI is picking up the draft better, fighting harder without cutting corners, and generally taking realistic risks. I typically have the AI strength set 110+ and medium aggression. Yes there are times where they’ll slide up the inside and punt you, but more often than not, I share the blame because I left a hole open and closed the apex when they made it along side. Don’t know what it’s like with the new 2000’s endurance cars, or formula cars, but for me I’m enjoying the racing more and more and it’s getting harder and harder to understand the criticisms. Kudos reiza

 

Every car, every track with chicanes. When you are in front on the inside before the chicane, they won't break to get get the corner properly, but try to hold position by just cutting the corner.
Player would get a warning/penalty for such behaviour, but there are no rules for AI.

Edit: And if there is a barrier or tyre wall in the corner, AI rather crashes into it than to break and try to pass the curve properly.

When leaving pits in training/qualifying, AI immediately goes full blast to the racing line, no matter if a car on it's fast lap is approaching. Then, they start blocking the fast car.

 

It was common for the races not having many overtakes, specially in the 00's. It was not common having 3-4 car packs racing within a second of each other for 20+ laps. Apart from the Trulli trains on some tracks.

Also one of the main issues for me is how unnatural the pack racing looks on the formula cars most of the time. Not necessarily the gap, you can have pack racing in the mid 00's F1 cars as it could happen due to the difficulty in overtaking, but have them realistically spaced, not taking the corners glued to each other which is the case most of the time. I think it happens due to the AI super brakes when behind another car entering corners.

But it doesn't always happen, I did a race at Hungary with the F-V10G3 and the AI where properly spaced and it looked more natural, not perfect but much better.

 

Since all the series are being updated, at various times to various extents, it would be helpful to keep detailed comments about AI in the AI thread and to note, as happened here, exactly what series is commented upon. That way, we can figure out what elements of the "train" behaviour might be series-specific versus general to all series. For every comment of a boring train, we have an example of good AI behaviour. And, F1 in real life has been mostly boring trains with mostly predetermined results for decades, so do we want that accurately simulated or not?

On a serious note, it is useful to try to dissect what precisely is causing any train behaviour (AI braking, AI reluctance to pass, AI not being affected by aero enough, etc., etc.). Because some series will be affected more or less or not at all by some of the factors.

 

Well, usually overtakes start when someone makes an error in the previous corner.

Maybe thats the key - to have AI make minor errors.

And then the AI that is behind cant be stuck centimeters from the bumber, because then they cant take advantage of the first AI error on acceleration.

 

Even when AI makes errors (or the player) the AI basically always slams their brakes instead of going for a clear overtake move.

 

The AI still ignores the draft of the player. It is unfortunate that this feature was implemented for a very brief moment back around the time the modern Le Mans track was added and just as quickly it got removed.

Videos showing AI point of view, i am the car ahead, the AI drives as if i was not even there and follows it's idea of an ideal line instead of using the possible slipstream from me.

 

Just wanted to take a small bit of Renato's post and ask a question...

Even to a lesser degree, are AI cars impacted by dirty air then? Are they impacted by wind changes? Specially the later; I got the impression before that they were nearly inmune to wind, which meant certain racing conditions delivered unfair racing vs them.

 

v1.6.9.9
AI strength 112
Aggression Medium
AI mistakes 2x

Practice Session
Watkins Glen
GT3 Gen 1
Turn 5

On page 123 I posted about this. I managed to capture a video. In that post the Aggression was High. The AI was cleaning me out at Turn 5 consistently. Lowering Aggression to Medium prevented them from cleaning me out but the behavior is still there. In the video you can see on the radar that the AI suddenly changes course and dives into the corner even though I'm right there.

 

Did it hit you? A view from outside the cars would be more useful. Should it have backed off as soon as you nosed ahead of it going into the corner? No, because then you could muscle your way past them at every corner, which was the old AI standard behaviour.

Not sure what this is showing other than an AI remaining committed to try to pass on the outside until it became apparent that would not be possible and it backed off trying to get back on the preferred racing line.

The issue of the AI ignoring our presence when alongside has been (and may still be) real, but this is not a good example of it IMO. I think if the bus stop chicane is utilized, a lot more instances may make themselves known

 

v 1.6.9.91.3398.AVX
Maserati GranSport Trofeo @ Interlagos Historic 1976
AI strength: 105
Aggression: Medium
AI mistakes: Standard
20 min qualifying
20 min race
Default Date, 16:00 start

First of all, I would like to say that Interlagos Historic 1976 is an absolutely fantastic track in Automobilista 2. It has a great flow, a very unique character, and is simply a lot of fun to drive. Because of that, I would really love to see the AI improved on this layout, as I think it could make racing there even better.

I tested the track with the Maserati GranSport Trofeo and noticed a few areas where the AI line / AI behavior seems to be weaker than expected. In my opinion, there are two sections in particular that stand out, and I feel these issues may have existed on this track for quite some time already.

The most obvious one for me is Curva do Sol, especially the second and final part of the corner. The AI seems to lose quite a lot of momentum there, which allows the player to gain a significant amount of time. In some situations, it is even possible to overtake several AI cars at once through this section. (look for example at 16:50-17:05 where I can gain so much time or 19:47-20:00)

Another section where the AI appears to be too cautious is the fast left-hand kink after Subida dos Boxes, shortly before the start/finish straight. As a player, you can carry noticeably more speed through this part of the track, which again makes it relatively easy to gain time on the AI. (timestamp 21:06-21:20 or 06:14-06:24)

There are also a few other corners where the AI behavior might be worth reviewing. At Curva 4, for example, the AI does not always seem to follow a very precise or consistent line, which can lead to a noticeable loss of speed. (timestamp 07:00-07:09)

Subida do Lago also feels like a corner where the AI struggles, especially in the second part of the long right-hander. It often does not get a strong exit there, making the cars quite vulnerable on the following section.

I also often had the impression that I could carry more speed than the AI through Laranja.

Overall, Interlagos Historic 1976 is a brilliant track, and I would be very happy to see the AI refined for it. With stronger AI behavior in these specific sections, racing there could become even more enjoyable and competitive.
