December 10th 2024 ai thread

Okay. Maybe I'm just spoilt from the drivers nowadays, who don't cause these scenes anymore because of the fear to break half a flap off and lose 0.5 tenths per lap.
At 1:16, I didn't think about the S40 overtake, as that was perfectly fine, but the line of the 850, which was not. Sorry for not making that clear.

 

Frx22 at hungaroring, tested in an 18 lap race with 20 ai at strengths 113, 115 and 117.
In turns 1 and 12 the ai fairly regularly have rather interesting moments like these:
The ai are also either early on the brakes or slow down a lot for a lot of corners, mainly turns 1, 2, 6, 12, 13 and 14. To make up for that they then tend to accelerate earlier than what i can manage.
Other than that the frx22 ai overall seem to be rather slow for a given strength. Both here and at the red bull ring i turned up the strength way higher than i would for say a gt race.

 

Update: the same happens on Diepholz with the Calibra.

 

Hello,
I found a car that provides good AI racing at Pau-Ville, the Crossle 90F. Very nicely done!

Still, some things to say:
1) At the start, the AI suddenly pulls to the right (As in my post above with the WTCC 2013), even turning straight into my car.

(WTCC post: #90, https://forum.kw-studios.com/index.php?threads/december-10th-2024-ai-thread.19812/page-5#post-255410)
2) The AI leaves partially big gaps in the hairpin, gaps which fit more than one car.

3) In the left-hander after the chicane on top of the mountain, AI cars often slide a bit more than they should. It's very easy to do that in this corner, but it happens almost every lap and it's usually more than one car doing that at a time.

 

WTCR 2022 at Macau (driving an Elantra, starting from the back I think)
Solid AI, with some problems in Lisboa: I've had two or three starts, and every time some AI car would lunge up the inside of at least on other car, hitting the wall on the inside and causing chaos in the following.

In the first lap (and I'm not sure whether there was a case in another lap as well), cars which are forced to cut the curb in the last corner were very slow and not even accelerating normally after they had all four wheels on the track again.

The AI works very well on this track. If you ask me, they're a little bit too fast out of Coppice corner and brake a little bit too early for the Melbourne hairpin. But that can be due to my skill issues as well.

 

Something in between the video posts:
I'm not sure if you are fully aware of that: You can create a single event with AI at the RaceRoom Drift Area. In practice, they will drive around a bit, but race is not working at all. They all instantly and synchronously turn left into the fence and spin their rears, until they reverse, try again and quit after some time. Maybe just deactivate the Drift Area for singleplayer events.

In every lap of my 10 minute race, there was a yellow flag in turn 1. As ShortyBuzz already said, it is a corner that is prone to incidents, but it shouldn't be every lap. And of course, it is partially ridiculous how the incidents arise. The most common mistakes are AI braking too late, but as they keep trying to make the corner, they end up in the barrier.

Only happened once, still worth mentioning in my eyes: very bad rejoin of a Vectra out of what is turn 5 to me.

P.S.: Apart from that rejoin, that 10 minute race was superb racing. AI well balanced, kept fighting with me and each other, no big mistakes, lots of door-to-door and side-by-side action, just perfect touring car racing.

1) BMW dominance could bore fans...

But only in Qualifying, not in the race.

Should be the other way round, at least that's how we know from DTM 2024 and 2025.
2) AI extremely prone to crashes in turns 2 and 3. I was punted from behind in my first two attempts of making that race, the third one is shown in the video.


3) The general problem with too much speed accelerating out of corners appeared again: I thought that this should be the biggest weakness of the Porsche, but he just flew by my McLaren. (All the other cars passed me as well without any effort in that corner).

There was a yellow flag in the right-hander before the uphill chicane. Some cars were slowing down a bit, which is ok, but the Mamba was almost stopping even before the corner really started. The AI was extremely slowing down. You can also see the SSR Lamborghini overtaking several cars under yellow flag, while I (in the first McLaren) had to give back the position to the Mamba. To make it perfect chaos, the Ferrari that spun out rejoins directly in front of the other McLaren and takes him out of the race.

 

Has probably been reported before, certainly for other classes, but i just did a practice session at zolder in the silhouettes at 106 strength and the ai are way too fast through turns 2-4 (mainly exiting 2 and through 4) but then are too slow in a lot of other places. They lose time in the turn 5 chicane by just not carrying enough speed/not using kerbs enough, similar story in the turn 7 chicane (in the faster right hander thats somehow still considered 7 theyre slightly too fast but theres bigger fish to fry ), theyre slow into the turn 8 hairpin and they brake very early and slow down way too much entering the left hander of turn 10.
The sector times are from said practice session and show the imbalance quite well: even the slowest ai (which on the whole lap is 1.3s slower than me) is 0.4s quicker than me through sector 1. On the other hand even the fastest ai loses 0.7s compared to me through sector 2.
Since the video is uploaded already and some of those differences are visible there ill also leave that here: In the rear view mirror you can see how much i gain through the turn 4 chicane, looking forward the gains through 7, into 8 and crucially into 10 can be seen. Id guesstimate i was maybe 0.8s behind that ai before braking for turn 10, had that been 0.6s i wouldve rear ended him because he was going that slow

 

Thank you for all your work/effort in raising attention for specific AI improvements!

Track: AVUS 94 & 98
Car class: STW
Difficulty: 95%

First report: There are still multiple issues on the first hairpin(Neue Sud-Kehre):

Issue 1: Similar to Salzburgring, the AIs have better brakes than the player:

At the start of the braking zone(me in the Volvo)


At the hairpin

Worthy noting: Some AIs have also outpaced me by almost 0,6 seconds in S1

Issue 2: At times the AIs will head straight into the wall and I have also caught traffic jams still happening there:



Issue 3: The AIs can also go kamikaze on the player:

In this photo I am the BMW:


Second report: This has been happening since the track was released: The AIs have superior acceleration and exit speed out of the last corner Nord Kehre.

Before:


After(The Audi managed to easily sail by me)


This also is where I always lose out to the AIs although it is less of a problem on the 98 layout of the track since the AIs are more steadier on the flick before the long hairpin, it is worse on the 94 layout where I am beaten by between 0,2-0,4 seconds.

 

My bad Andi, but of course me doing it in a late evening before bedtime wasnt so well planned. Here is a result(with AVUS 94):


And speaking of other AI errors, I also caught one of them driving the wrong way and causing more traffic jams

 

I just did a DTM 2024 race at the Red Bull Ring and the AI (difficulty 98) is too slow in the first half of the track up to Schlossgold. They are too fast in the second half of the track.

Spoiler: Track map

 

Yes I Garee on that, in the second half they drive away like LMP's compared to the GT3. For my case equal if I did 100% (2 times) and also adaptive (also 2 times).
