Official General AI Comments & Discussion Topic

Which difficulty are you playing on? I tried with GT cars on 110 and they are really good through Carousel!

 

I think it was 105 from memory.

 

Serious question.....after all these updates, adding new content, fine tuning the AI, scalars after scalars, why haven't these sorts of basic AI issues been fixed? I was hoping the last update might fix it, but nope!

 

Can you explain what happened there ?

 

Drive Silverstone National and you'll see, AI can't take T3 (can't remember the name) because of the wide line they take through T2, been this way since it was released

 

they probably haven't gotten to it. with the amount of content, there's an infinite number of permutations to go through.

 

Released in 2020? Obvious issues should be fixed prior to adding more content, all these new AI refinements mean nothing if they can't stay on the track!
Maybe they need to release a AIW editor so we can fix these issues ourselves?

 

If Reiza has to go through every combo possible to fine tune the AI, they could publish a compiled list what they have gone through already. Otherwise it is just a guess game for the player

 

That's what I thought this topic would be for...
Track layouts to receive AI line redos
....but nothing ever gets fixed

 

Calm down, it's not as simple as redrawing the AI line per track.
From what I know there's an AI corridor (wider/narrower in places) AND gazillion of AI parameters too. It's a combination of those to make the AI behave. Combine this with changes to physics/handling redoing the AI behaviour is a wasted effort since it'll need to be redone later.
The game is under heavy development and some things will be out of sync.

And there's been so many improvements to AI already. Just because some of your examples haven't been addressed yet doesn't mean they're never fixing things.

 

What has been catching my eye since early days of the game is that the AI come much too close to each others in all car classes. So, instead of going for a gap which is there, they stick to the line and ram car in front instead of passing it.
In ovals, they just move from outside to inside in corners without giving a damn if there is another driver. As their cars are reliable as tanks, they do not have too many casualties there. But when they make those dirty moves against the player, he gets rammed out or at least has damage, as his car is not as reliable and the physics are different, which makes him spin out quite easily in such situations.

If AI's cars had the same "damage parameters" as player's car, they would spend more time in pits than on track because of that continuous ramming and touching each others.

 

The AI are ALWAYS being worked on.

There has been a raft of tracks and layouts that have been fixed in recent updates in terms of AI calibration. My current list of tracks that still need fixing has been reduced to about forty. Some, like Mosport, had a recent fix (v1.6.7.2) from an issue stemming back to v1.6.4.3. It had been previously fixed in v1.5.9.7 after its release in v1.5.9.6 (in Beta).

Adelaide has also been recently fixed alongside Ibarra, Hockenheim GP, Curitiba and others. Some have been out of kilter for a long while and some are more recent disparities.

Silverstone National has been one of my test beds since about v1.3 and I've driven pretty much every car there but I've not experienced issues at Maggotts any more than at any other venue. I see more incidents at Donington GP/Nat, another test bed, and still not calibrated properly since v1.2.5.0 (October, 2021), or one of the Buenos Aires layouts, also uncalibrated since its release in v1.3.8.0.

 

Please don't be too harsh—encourage them gently. I have posted countless threads on the LMU forum next door reporting AI issues, and although they have updated multiple times, my requests have been ignored as if I were invisible. For an entire year, not a single update or fix, not even a single word, has been related to the AI or single-player mode. Yet, look at Reiza—they are so diligent and proactive in fixing the AI! They have never abandoned single-player players. Every update includes a section dedicated to fixes and improvements. All the AI control issues I reported here have been resolved. You have to understand how massive AMS2 is, with its vast combination of cars and tracks. It's already quite remarkable that the AI has reached a playable state today. I hope they can continue to improve.

 

I normally adore Imola. But boy are the AIs so rough! This was done with 110 % but it also does happen even at lower settings. Layout: Modern version


The AIs are too fast through Piratella (Turns 9 & 10) and they also tend to have better exit speed at the exit of Acque Minerali(Turns 12 & 13)
The only reason I could finish over 6+ seconds ahead of the rest is, due to the AI driving errors.

 

Bathurst is also very enjoyable, with just one problem at the moment. Through corner 2(Griffin's bend), the AIs have superior hill-climbing-pace!

 

Really frustrated with Le Mans.
Me, a buddy and three more people (engineer, strategist and spotter) trying to do 2.4h of Le Mans in a GT3 (with LMP2 and Hypers on the grid).
We've been trying for weeks. Can't finish a race due to being punted while driving in a straight line.

1) Not even in the braking zones - hypercar would drive through us on Mulsanne like we're not there.
2) In some turns the AI is egregious - e.g. in Indianapolis the AI would TURN IN into you despite you driving a STRAIGHT line and giving space for TWO car widths to the left. In the same turn if you exit the corner to the right they would sideslam you like in NFS.
3) Wet weather is whack. AI drives in the rain on slicks 15 seconds faster than us on wets, then switches to wets and drives 12 seconds slower than us on wets. It doesn't make any sense.

AI is set to 101. I'm lapping same as the top two - about 4:01:00 in traffic, sub 4 in clean air.
Aggression set to medium, mistakes to standard.

We review incidents and it oftentimes looks like AI had 1.5 car widths to either side of us but still chose to go right into us in a corner. Very frustrating.

Any suggestions?
(For the record I drove several vintage f1 championships before and didn't have this problem).

 

Since 1.6.6 came out it seems some AI strengths have gone up but only in certain classes. I run in the 88-90 range and in some of the classic F1 classes I get killed in a 10 lap race. F1 Hi-Tech gen 2 is one I remember in particular. But in other classes like V12 it's still about the same as it was before.

 

Reporting on some multiclass AI issues on Road Atlanta (lmdh+lmp2+gt3). The slower cars lift too heavily, even on straights when in the blue flag scenario, too much so that it makes them incredibly trivial to pass. Being in the same class, and behind an ai, if any faster class is approaching it will slow down to almost a halt, complete ai trains too. I have not tested this on other tracks, but here it is quite obvious. In my opinion, instead of lifting they should stick on one side of the track.
Also on the straight at turn 9 (right hander before chicane), they defend to the right being the inside, but making it extremely easy to just sit on the left to overtake them in the chicane where they are quite slow.

 

I think is related to the new blue AI behaviour:

• Minor global adjustment to how much the AI cars slow down under blue flags and how far behind the car behind is before it begins getting out of the way for GTE, GT3 (both gens), GT4, Stock V8s, Super V8, Lambo Super Trofeo, Porsche Cup

I reported that in the patch topic, but this made multiclass against AI in those classes undrivable. The AI as soon as they get blue flagged stop any kind of fight for position and even let go of the throttle, sometimes even braking on straigths while the faster class is still a bit away. You can easily pass all AI when the faster class approaches.

The core issue is that this is not even how Blue Flags work for those classes. Blue Flags literally just means "a faster car approaches" so they should be aware of faster classes / lapping cars trying to get through. It's the faster cars job to wait for the right moment to pass safely. The blue flagged cars should never slow down or let alone brake on straigths to let others through and definitely should not stop fighting for position.
