Official General AI Comments & Discussion Topic

There are tens of thousands of car&track combinations in AMS2, and calibration is a case-by-case basis. So yes, AI combinations are still being calibrated and will continue to be updated with future AMS2 updates.

Both AI vs. AI and AI vs. Player. Aggression determines both how determined AI is to pass, as well how determined AI is to defend. By "determined" I mean how likely the AI will try to engage in such behavior, and for how long it will attempt until it gives up either the pass attempt or the defense attempt. Passing attempts also depends on how wide the drivable AI lane of a track is in that section - if it is too narrow, no attempt will be made. If it is too wide, AI cars will drive on grass or crash into guardrails. See also Track layouts to receive AI line redos

 

Sad we can't change AI mistakes in multiplayer.. I've been having so much fun making chaotic races with 3x to 5x mistakes turned on. Wanted to share the experience with my friends only to see you can't change it. Even though it clearly states "Standard"

But when you open the options it's not there.

 

This is what I ment about the Ai train and sometimes you can' t overtake them because they will push you of track.

 

Is there anyone who can confirm some combinations where the AI calibration is "finished"? And I realise it will probably never be completely done but some stuff that is done for this release.

I've just spent a frustrating hour getting murdered by the AI in the LMP2s at Nürburgring Veedol during qualifying with Aggression at Medium and AI Strength 105%.

I'm starting to get to the stage where I think the limitations of the engine are the problem and we aren't going to get close to what we would like despite Reiza's best efforts

 

The only actually GOOD experience with the AI i managed:
Suzuka (Kansai) GP, GT4, GT3 Gen2 and LMDh, 1 hour race, 24 hour day and night cycle, medium aggression and difficulty to what suits your pace. They are actually able to move around, overtake, give space, and you can have an actual GOOD race there. Only combo i found good so far.

And no, i refuse anything about the AI being "madness engine limitation".

 

Thanks I'll give that a go tomorrow.

 

Let me know what was your experience after you drive it.

 

Oh that's why I was mostly having fun, I only race at Kansai for like, 90% of my time. It's my favourite track, what can I say?

 

Possibly calibration could be prioritised for ‘correct’ combos of class and track? E.g the ones that appear under the presets.

We can’t reasonably expect fabulous AI racing with LMDh at Cardwell park?

Now many are running larger fields could compound things as well.

 

It's not really worth letting yourselves get triggered by thumbs ups / downs or whatever.

 

Anybody tried these AI files yet?

Is it just me or is the F Ultimate Gen 2 AI at Suzuka really bad? Just trains of cars despite one clearly having an issue, and some cars really just slow for like a lap and then they speed up.

Can anyone perhaps test this? Start at the back and give them a 10 second or so gap, and see how quick you catch them at your normal AI level. AI aggression at its highest doesn't seem to help either, they just keep in a train.

 

Had a great multiclass in the Audi GT3 (25 cars) / LMDH (20 cars) race at Road Atlanta - AI on 105 / high aggression and x3 mistakes).

AI were fantastic and the LMDH were pretty effective at getting through (came through the GT3 field 2-3 times) and not causing chaos in the process despite the roller coaster nature of the track.

AI was no problem, but the FPS tanking from 120 to mid 40s towards the end resulted in me losing focus / making a fatal error and ending an otherwise fantastic race.

 

Have you witnessed the AI taking shortcuts like this ?

 

The LMDHs were passing on that corner a bit, but cleanly on track - as that would have been 10ish laps in it wasn’t too congested though.

GT3 did go through the grass twice in the chicane at the end of the straight, however that was more due to me not giving them space through there.

So, good news - Confirmed - for classes where fuel and tires happen separately during a pitstop, like GT1, the AI will double stint their tires, sometimes - rarely, but it's not never, and not just in cases of splash and dash.

They are very, very sensitive to wanting to change them currently - so they won't double-stint their tires effectively during the race as the player might. But, I've seen them do it, they will choose to not change their tires and only fuel to the end of the race with 15 minutes to go. It's rare - and the rarity does give the player a big advantage - but they do do it.

Another good thing, is that they are smart in the amount of fuel the use, how much they refuel, how they calculate how much fuel they need to minimize the amount of time in the pits is quite good, in fact. They've outsmarted me now two races in a row - where I was on purpose changing tires as they would every time so as to not get an unfair advantage, and they were beating me out of the pits by minimizing their fuel intake during pit stops. I was filling up to the brim every time, costing lots of positions.

Hopefully this gets sorted soon. Once it does, jeez, I can't think of any other deficiency AI-wise. The on-track action is honestly amazing.

 

Yep, I knew about how they know how to fuel on most classes (in the GTP its still a bit inconsistent)but them double stinting the tires is new to me, nice.They should definitely fine tune it for when the AI use other compounds to improve the endurance races.

 

There are still many AI deficiencies. Like how they cannot pass a car on the side of the road, how they are braking excessively instead of going around a slow / damaged car, how they need to make sure it is 125% clear to overtake otherwise they do not and instead brake and go single file, how they go single file in nonsense places instead of going realistically two or even three wide, how they can cut corners and receive no penalties for such driving, how they are ignoring the player's draft since 1.6 even though before the last update they followed it properly ... the list goes on but here is a video showing just some of that stuff.

 

From my experience, they almost always end up needing to pit at least once more than me, sometimes with less than 5 minutes left in the race. What settings were you using when they did this?

 

This is for endurance GT races, with 1.6, x2 fuel and authentic tire wear gives excellent results. They'll pit when they need fuel at an entertaining accelerated pace, unless you wanna go for the default authentic and authentic, which will also work great.
