No.

Was in championship mode, no time or tyre wear/fuel acceleration, 1hr medium cloud to light cloud and sync to race, default date (manually set as custom date because default date doesn't work correctly in championship mode). AI at 110, rules on, flags and saftey car on, 60 km/h pit speed limit. Custom AI @ 110, custom liveries. Game decided to load the low downforce car for practice (yesterday), regular for quali and race!?

AI were around 2 seconds faster when not driving the low downforce car.

Love the game but all these little bugs and inconsistencies make it frustrating to say the least.

 

QUESTION: Is there a way to callibrate our AI co-driver?

I was thinking about doing a 6, maybe even a 12 hours endurance race and swapping seats with the AI. I've done a few small tests and so far my main concern is that our virtual buddy loses A LOT of time behind slower classes.
Maybe, if I could increase his aggressiveness or any other parameter that would affect overtaking decisions?

 

For what it's worth, it's not just your co-driver, it's the entire field that has issues. The current AI seems quite bad at passing from what I've seen.

I've been doing a lot of 150km races lately, and with every qualifying session I get more convinced that the blue flag behavior was pushed to production by accident and Reiza are keeping it in because they're too embarrassed to admit to their mistake. I know it sounds harsh, but the absolute kindest thing I have to say about it is that the amount of times I've seen cars successfully get out of the way is not zero. Most of the time though, what they're doing is worse than nothing.

There's some clear avenues of improvement, though:

• They should never attempt to yield their position to a car that isn't giving them blue flags. Currently if you follow a car out of the pits it will immediately try to let you pass.
• Like in rF2, there should be a grace period after a car has just passed someone who normally would get them blue flagged. As it is now, fast cars that are a lap down have a bad habit of harassing you and trying to get alongside, only to lift the instant they count as being ahead.
• Adding to above, cars not on a fast lap and cars a lap down should probably be discouraged (though not entirely stopped) from trying to pass cars a lap ahead, and conversely fast cars should be WAY more aggressive with diving up the inside of backmarkers, and probably in general too.

 

I doubt it's by accident, especially after their transparency about the stock cars leak - they are honest when they make a boo boo. They tend to release the initial foundation of a feature out and then tinker and improve it with subsequent game updates. This is how pretty much every new feature was delivered so far.

I suppose the reasoning is somewhere along the lines "let's give players something for now, it's better than nothing at all" which would be in line with pre 1.6 complains about the lack of deliverables. And personally I like this approach where everyone can benefit from new shiny-shiny even if it's not polished yet, rather than waiting long months or even years and only then get the feature.

 

Well, yes, I was hoping that it would be a wild enough claim to be understood as an exaggeration for comic effect.
It has been almost a year and a half already though. I realize these are subjective observations, but surely I'm not the only one frustrated by the state it's been in for quite a while already?

 

After 1.6 shenanigans I'm struggling to detect any pinch of exaggeration in a written form anymore
A lot that I'd attribute as pure trolling ended up as a honest opinion hence my miscalibrated detector.

 

Track and layout used: Daytona Sports Car Course
Car: Lamborghini Diablo Super Trofeo
Ai settings: strength 110 (I ran first with a 1.51.5 ish)
Report 1: The AI is very slow on the banking, especially towards the finish line. I think I am about 20 kph faster)
Report 2: The AI breaks very late into corner 1 and into the busstop. Especially corner 1, they break probably more than 50 meters later than I can.
Report 3: The AI that is on an out lap or in lap tend to yield through turn 4 (dogleg). This makes it very awkward to overtake as there is no room to overtake there if you are on a fast lap.

 

Are there any 3rd party tools that assist with calibrating the ai difficulty on each track, wet and dry?

I'll just hop on AMS2 for a quick single race every now and then for the immersion factor. I no longer have the trial-and-error patience of dialing each track in, both wet and dry, before each race in order to have a competitive championship..

 

Lambo Diablo also Group C C9, modern layout of Spielberg. I tried 2 races (medium then low aggression) 100% AI. I was getting punted from behind while braking in a straight line. My lap times were similar to the front two AI (I qualified 2nd and my race laps were close to the best). At the Remus turn I was getting punted regularly. I'd be exiting the corner and the AI would PIT me. At the Nikki Lauda Kurve I was getting hit in a straight line from behind as I was braking

I tried a GT1 racecar Long Beach in January and I could not manage more than a few laps before I got spun out by AI. T8 and T9 are impossible.vAny contact is a PIT Maneuver and you're race is done. At T4 there was contact on literally every lap where AI was close- it's so tight and the AI is so aggressive there's no way to avoid it. But it's slow enough that they generally don't spin me out.

 

Would be good if you recorded a video and also shown with chase cam how the AI spins you out. Writing about "AI hits me and ends my race" does not show if the AI is at fault or if that is just players exploiting AI and getting taken out in the process.

 

Renato mentioned about AI pitting humans in the notes for the October patch. It's a known issue, and there are so many videos already out there I don't feel it's necessary. The latest patches have just undone the work they did before and Reiza should really be working on it. The latest patch notes say that the AI has been made more aggressive. This has brought the AI back to a worse level than they were before the October update.

If you've never experienced it you haven't been doing very much offline racing. It makes it so that you can't race the AI close. Which is to say you can't race the AI at all. AI refuse the slow down if they go off circuit and with the extra AI aggression it makes it so they will pit you or go off track to pass. Do an AI race at Nords.

 

"There are so many videos" .. i have not seen a single one, please share them. From my tests the AI has many flaws but i never got pit maneuvered.
And what Nords, modern Nordschleife ? And with what class ?

 

Having just raced the AI in the wet properly for the first time in a long time I'd thought I'd share my thoughts - Road Atlanta - Ginetta G55 - 120% Skill - Aggression Medium - Mistakes x3 - Wet Scalar 0.97;

1. The AI are far too "clean" in the wet, like they're on rails, there's zero twitchy behaviour, they drive over glossy kerbs with ease, no visible signs of mass wheelspin etc.
2. They're able to get power down far earlier than I could in some instances
3. The age old AMS2 problem of having Super Braking Abilities even in the wet as coming down the hill to the final chicane area they're able to brake far far later and still make the corner with ease. (this happens in the Dry as well with various cars at various tracks, reported a long time ago)
4. Major Bug (noted in the Bug Thread) was that as soon as the Rain stopped so did their lap times, they began to drive very slowly which made passing extremely easy and then they failed to pit for Slicks when it got dry enough which completely ruined the experience.

Aside from that (!) the first half of the rain in full rain was actually a lot of fun, I'll certainly race more in the wet against them (in other Cars/Tracks) but the #4 issue above needs attention as it currently makes Wet to Dry races pointless unfortunately (this may or may not happen to other cars/tracks combos of course).

 

Agree with the first 3 issues, but about the 4th, did you have mandatory pitstops on? From my experience, in that case the AI tends to think they already did their mandatory stop, so they don't need to pit again, and end up staying to the end on the wrong tyre, while, if you turn mandatory pitstops off they change to whatever tyre is adequate based on the conditions. Could be wrong though, has been a while since I raced in a wet to dry transition. But I have dealt with plenty of dry to wet transitions recently, and they worked fine for me if I turned mandatory pitstops off.

Was that after lap 1? Long Beach has a pretty terrible issue when it comes to Lap 1 behavior of the AI where they literally ignore the player's existence completely, literally drive into you on the straight if you get a bad start and turn into you in every corner. But as soon as they cross the start-finish line to start lap 2, they suddenly get very fun to race against.
From my experience, at Long Beach the AI have many issues when it comes to speed, there are sections of the track where they are very fast, and others where they're way too slow, but racing in general works quite well for me. And both GT1 classes are among the most well calibrated in the game currently, so I wouldn't expect it to be a bad combo initially. I might try it out myself.

 

Turned Off.

 

Track and layout used: Monza historic 1991
Car: F-USA Gen. 2
Ai settings: Strength 103, Agression high
Report: The AI reaches laptimes of about 1:25 if you have the full qualifying run in normal time. It does about 1:21 if you jump to the end of qualifying.

 

Track and layout used: Spa 1993 (applies to all Spa layouts though)
Car: Lamborghini Diablo Super Trofeo
Ai settings: 105%, medium aggression
Report: AI is much faster than what a human is capable of through Eau Rouge/Raidillon. AI is also very slow at La Source hairpin.

It seems to be a general theme in all Spa layouts where classes that shouldn’t be able to take Eau Rouge/Raidillon flat will have the ai able to consistently do just that and it doesn’t seem like it can be replicated with the physics of the player’s car

 

I regret to say this, gentlemen, but "artificial intelligence" doesn't exist. Only humans possess the ability to "think." What exists is parameter programming, and these will NEVER satisfactorily approximate human reactions. We have to make do with what we have. In AMS2, to avoid wasting my time and patience, I always drive with tire wear and fuel disabled and fixed weather. Yes, it's frustrating, but it eliminates a dozen variables that end up being even more frustrating when they cause bugs. Life is short, and every minute of my free time is for fun, not for racking my brain because the AI didn't stop in the pits, changed the wrong tires, or any other anomaly.

 

BOP of GT3 cars (104% AI, if that matters)
Running a race with 47 GT3 car (Indy road course). After finishing qualifying, the top 7 cars were all Aston Martins. The next 8 were Lambos and Vettes.
Doesn't seem like the BOP is working

 

There's only so far it can work, really, since real-life BoP is adjusted on a per-track basis, and doing that for every car in every class for every track in AMS2 is not a reasonable thing to ask. Of couse, it would be possible to just make the cars more similar, but that seems to defeat the point of having different cars in the first place.
