Official General AI Comments & Discussion Topic

What's up with Imola? I run 98% AI and on most tracks I'm pretty competitive, probably could raise it a bit but time is short so want to pass some cars at least, but at Imola... I'm 5 sec a lap slower AI are soooo fast it's ridiculous!

 

I do not have this problem.
Which car are you driving?

 

GT3 and PCC, don't think it matters though

 

Found a strange issue: Did a qualifying in private mode.

The positive thing: AI achieves much better laptimes than in "public/standard mode", as they drive alone on track without getting stuck in traffic. If you are using a custom AI file, cars will be separated according to the skills you have given to the drivers..
BUT: Some drivers are constantly aborting their fast lap and return to pits for no obvious reason, as they do not get blocked by any other car. I was watching a session in spectator mode, and there was an AI which did not manage to finish a fast lap within 20 minutes.

 

I concur with muzarati. I race on over 120 of the 166 layouts using over 80 cars on a regular basis and never change the AI level. I use Custom AI files to effect the changes and currently the four worst tracks for me (vs AI laptimes) are Imola_GP_2018, Buenos_Aires_Circuito_7, Jacarepagua_OVAL and Spielberg_Short. I reduce the driver Race_skill to a level roughly equal to an 11% drop on these tracks but 12% at Imola.

For me right now, there are 129 tracks that aren't affected and 28 that are handicapped by 1 to 5%, 5 by 6% and the above four by over 10%.

In all the time I've been using custom AI files there have only been two times when the handicap has been different between different classes; once a long time ago at Oulton Park Classic and currently between the GT4s and GTDs at Brasilia_full.

 

Gave it a try on those tracks with some open wheelers, which I drive most of the time.
Did not have to adjust the AI strength.
There is one exception: Jacarepagua Oval.
With cars like Formula_USA Gen 1/2/3, where you have to leave the pits with stone cold tyres whilst AI have maximum grip right from the outlap, I have no chance at all. They drive circles around me and I just can not get my tyres to optimal temperature.
When driving cars which have warm tyres when going on track, it is quite ok to me even on this oval (beside the fact that AI love to ram you off track in corners).

 

Deadly, thank you for your response but it doesn't really help me.

When I handicap the AI, I don't use my driving skills alone (what a foolish thing that would be!) but check the Leaderboards as well. I compare my lap and sector times (using the online facility) with those on the LBs. At my best (and, sadly, only at my best) I can match and sometimes beat times set by The Drunk Penguin, Sim Racing Rudi et al to be confident in my skills at any particular track.

The AI at 120%, running 10 mins of private qualifying - so not affected by draft or artificial speed boosts - are commensurate with, or a second or so slower than, the top LB drivers at balanced tracks like Silverstone GP, Interlagos and Barcelona GP (NC).

The AI at 120% at Imola are two seconds clear of those drivers but at a 12% reduction through Custom AI files they are in line with more balanced tracks.

I used the V10 and V12 cars for testing and found my speeds commensurate with my times at other tracks vs the LBs.

 

Ah, I get what you mean.
But "muzarati" was talking about the AI being hyper fast in Imola compared to other tracks with his usual strength of 98%.

Formula USA Gen1/2/3:
Out of slow corners, AI is extremely quickly accelerating, although they often almost stand still at the apex and I can hardly avoid a crash going behind them.But then, vroom, they pull away from me, whilst I have to be careful on the throttle because of the effect of the turbo.
Is anybody else experiencing the same or is it just because of my lacking driving skills?

This behaviour (rocketing out of corners despite a poor entry) was a general issue in early builds of AMS 2, but it was reduced in the other vehicle classes I usually drive most of the time.

 

Which tracks/corners ?

 

For instance the hairpins on tracks like Spielberg GP, Kyalami (Modern) or Donington (last sector). They almost stand still, I come extremely close, but after the exit, they drive as if they had some kind of TC, whilst I am struggling with getting grip.
In all those extremely slow corners, I just can not keep up after the exit.

Edit: Out of "corkscrew" in Laguna Seca, where there is some kind of compression, they rocket out of corner they almost stand still up the hill, though.

 

Are you sure this isn't just a slow in - fast out issue of yours? Like you go in way too fast, so you catch up in corners, but you have to delay your throttle application way too much so they get away on the straigths. Would be great if you can record a clip of this.

 

No, because what the AI does with those cars is not slow in - fast out but standing almost still on apex like on race start - fast out.

 

Yes, precisely - it's the 'compared to other tracks' bit that's the issue.

I run the AI level quite high but I'm over 70 and have been sim racing since the mid 1980's. Muzarati runs the AI at 98% because that's his level. When AMS2 was young and the AI skill levels were linear he would need the AI to be at 86% at Imola to match his AI race pace at Silverstone, Sebring, etc.

Some time ago the AI skill level was changed to a more compressed time difference around 100% and further apart at the edges so muzarati may have to find out what level the AI need to be adjusted to to match "his" lap time. For me, Imola works at a 12% reduction and at 98% that still works out at 5 seconds a lap as noted in his post.

If you're still following, muzarati, these files should work, by my calculations, for your level. Try them and see how they work for you. I use these names (handicap, chassis, decal) for easier testing in Beta. You should be able to edit the names yourself in a text editor.

 

GT3 Gen 2 AI is running 1:41s in Imola in race trim with 115 difficulty.
This is basically the current time attack world record ^^
My previous gt3 race with same AI settings on Interlagos was basically perfect, had to build a setup throughout practice/qualy but was able to fight top 5 in the race, in Imola no chance at all.

edit: game version 1.6.7
lap times by AI seem to be the same in 1.6.8 but i found some more speed and confidence by the adjusted physics and ffb.

Yet still dont really see a chance for 1:41s though

 

V10 Gen 2 AI times are very slow even at 120. I'm about 2 seconds faster. They're very slow in the 2 Degners, exiting Spoon and fast on the entry to turn one.

 

It seems like no matter what the AI is set at, when they're ahead of you, you get brake checked just before the apex, and when they're behind, they'll rear-end you.

 

As this behaviour (getting brake checked by car in front while being attacked from driver behind who seems to be blind) was reported many times since years, I don't think that Reiza will ever fix it.

Another annoying thing:
Dirty air effect is only there for player's car, AI seems not to be affected at all.

 

It's unbelievable they didn't fix that yet.
I had another weird race right now with 100% AI, Dallara F309 on Indianapolis (Road);
Even though I was faster on laptime, because of a corner error I lost many positions (first to mid) and I was unable to come back because of that.

You can't attack safely without being roughly attacked.
Also I can't understand why AI is kinda a rocketship on 2nd sector in Indianapolis.
It was half a second faster than me and everything on wet track.
The last one combined with AI divebombs makes the experience definitely frustrating.

I thought AMS could worth playing it for its AI but every combo I'm trying with Racing Life changes my opinion on it ... And it's worse, definitely.

 

The update in August that changed the AIs at Road America really did change most things at the track for the better. But there are sadly two new issues at this track:

The AIs are awkwardly pulling to the right on the main straight even when they dont fight with anyone.
Sadly now AIs are aliens on the approach to turn 1 and braking exceptionally well and late compared to the player.

 

Yes i`ve noticed this as well plus their still too slow on the carousel corner.
