Has the "AI mistakes" setting stopped working in some recent update ? Even when i set it to 5x, nobody ever makes a single mistake !

 

Just like the vehicle reliability stat in custom AI, and default Reiza AI. The only reason that cars retire is due to running out of fuel or overheating (in high air temperature races, 2005 LMP1 Audi particular prone). 1.0, 0.0, -1.0, no effect whatsoever, the AI finish the race.

 

I get mistakes. Not every lap, but I run 15 minute races with 23 AI cars and I usually get a crash or minor AI mistake two or three times a race (that I notice) (other than the crashes I cause lol) on X5 AI at 90-100 and high aggression

 

I have my AI mistakes set at .5 and they still mistakes, they just don't randomly run off track. I've had it set like that for a while as before they just seemed to go of track far too often. I'd be running in something like 5th place having a decent race only to have two or three of the AI in front just go off track for no apparent reason which took the fun out of it.

 

well the ai does also race itself! if you look carefully there are two cars ahead of you closely battling

 

For me 1.3x is the sweet spot, the ai still makes mistakes but seldomly doing something that breaks immersion. It’s worth noting that in some circuits they feel more balanced than others, so I believe it’s there’s room for improvement, but I cannot fathom the possible car class/ track combination, so I assume there will always be some degree of inconsistency with regards to that.

 

In his examples you are right, they should be doing that, but I have noticed the AI doing it there when they are completely alone as well, so there's definitely something weird going on there. Besides, and this seems to be with all classes - noticed in LMDh, GT1 and GT1 2005, all very well calibrated classes - there are a few other things.
The AI carry a little too much speed through T1 and brake way too heavily at T5, the end of the back straight (It seems to me they have the right braking point, they just brake too hard). They are also brake slightly too early at T8, and seem to have a little more grip through the Kink (T11), which in some classes doesn't make too much difference (GT1 for example) but in others (like GT1 2005, with less grip, where you have to lift a lot and the AI doesn't) that difference grows a lot, and they can easily gain a second on me, sometimes more, just on that corner alone. Beyond that, they brake very early into Canada Corner (T12), making it relatively easy to overtake them there (if by a miracle you stay close enough out of the Kink). And finally, they miss the apex at T13, which in high downforce classes doesn't mean much, but in lower downforce classes they are forced to lift to not run wide, and lose a bit of time (similar situation to Abbey in modern Silverstone).

 

In-and outlap behaviour of AI in qualifying/training:

Since one of last year's updates, the AI on the outlap does not fight cars on the fast lap anymore, which is good.

But there are a few things left.

Inlap:
Here, they still race you like crazy, as if they did not know that they would return to pits.
Would be nice if they behaved just like on their outlap.

Outlap:
After leaving pitlane, they instantly rush to the racing line, which can be quite irritating, even if they are still ghosting.

AI on fast lap:
They still do not make decisive moves to overtake the cars on the outlap and crawl behind them for a long time. But this issue persists in many racing titles if not in all of them.

 

I have not raced there in a while, in that case it might me problematic, I was merely remembering the first corner. Just as a curiosity, do you race with the mentionned classes in multiclass? I feel like the AI recently tends to move out the way instead of sticking to the predictable racing line. If single class, totally agree that the move to the inside is unnecessary

 

F1 games do not have this issue last i played them, and AI not on an outlap yields, or the AI expects you to yield when you are not on a hotlap.

 

Thank you for adding that. This has happened since the late summer patch changed the AIs on this track! Before it didnt happen but back then there were other issues: Late lounge at turn 3 and being turtles through the Carousel

 

With those three I mentioned, I always use multiclass with LMDh (either GT3 or GTE), very rarely with GT1 2005 (GT2, but never drove with them in Road America), and never with GT1. Yet the issue remains, and even in the cases I do use multiclass, they do it without any lapped traffic even remotely nearby.

It's definitely a lot better than before, it used to be almost unraceable, while now I can have some great racing with the right class, but there is still work to be done on it.

 

On the modern Silverstone GP, I really get choked out through sector 2. And to be specific, I only lose it between Copse and the entire Becketts complex:
Done with skill level 110


And sadly, the historic Silverstone 2001 also has the Becketts complex curse!
Also done with skill level 110.

 

I tried to do a LeMans 24h with the 90's GT1 cars on the 2005 layout today and found something very weird. I set up a 2h20min race, x2 fuel consumption and tyre wear, x10 time progression, and a full 48 car grid (I was using mods, that's why there are more than 40 cars, but their behavior was identical to the base game cars). The racing itself was fine, the AI raced well (at least me, they did form quite a few trains but nothing unexpected), but I got very interesting results in their pit strategy. Of the 48 cars, only 13 finished. Almost every one of the 35 cars that retired, did so by running out of fuel.
FCYs were turned off, so it wasn't the well known bug of the AI refusing to pit under yellows, it was just their strategy. Every pit window some 5 or 6 cars would try going a lap too long. They wouldn't even run out of fuel at the end of the lap, usually they lasted less than half of that extra lap before retiring. Seems to be something wrong with the AI's fuel estimations. Putting it here because this is the first time I've ever seen the AI do something like this, has anyone ever experienced something similar?

 

Guys as AMS 2 is my fav game fix this please. AI in general is very good but have one big problem, rivals rear-end you and knock you out of the race. Some might call it a 'skill issue,' but in an long endurance race, u dont go 100% all the time, you want to be able to brake a bit earlier or coast into a corner without worrying that the AI will end your race by ramming you—which happens 100% of the time."

 

The slipstream effect is a bit too strong. You can quickly overtake cars on the straights even if their lap times aren't slower than yours. Would love to see this effect toned down, especially in GT-style races where it shouldn't be this powerful.

The AI is inconsistent and weird, to the point that trying to race it is just frustrating.

On qualy, they were too slow probably because they seem to be in a very high downforce setup, which is not beneficial overall in this track. Their top speed was 303kph, while I could do 310kph+ (I don't remember the exact figure). I was using the same setup as the fastest time in the leaderboard for the car/track combo. (BTW, I am 3rd in the same leaderboard, just to clarify that my performance should not be a bad reference). Their fastest laptime was 3m35.4, while mine is 3m34.9 (I can't get even close to my TT time in the qualy for some reason)

On the race, they were unbeatable. But in a weird way. The top speed wasn't good, but they ran in a pack and seemed to pull each other on draft. But more than that, they have magical grip through the fast corners and impossible corner exits. Their fastest time in the race was 3m35.0, faster than qualy, while I could not go faster than 3m37.0. I tried to increase my donwforce, but I could still not get close to their performance in the corners, and I was overall slower using this setup.

Those problems above seem to be very critical at Le Mans, but I didn't have that in Interlagos for instance.

Another point, less critical but it could be addressed, the LMP1'05 field is kind of boring. The Courage is way faster, the Dallaras come next seconds behind and the Audis are way down at the bottom, mixing up with the LMP2s.... Also, on top of being slower the Audis need to pit more often.

 

One thing I notice with the GT1 2005 AIs is that, they are so demonic and fast with the Aston Martin but worse in the Chervrolet Corvette and Dodge Viper!

 

I'm not sure, but I think that's just the cars. The Aston is by far the quicker car, the Maserati is the only one close, and occasionaly the Viper is fast on specific tracks. What I do think is weird about the AI on these cars is that the Aston, Viper and Corvette always pit very early, the italian cars can go for much longer, something around 1/3 of a stint. I'm not sure if it's the cars or the AI, but either way there's definitely something very wrong there.
