Calling for Better Assetto Corsa Competizione AI

Calling for Better Assetto Corsa Competizione AI.jpg
There is no denying its popularity for online races. But Assetto Corsa Competizione AI must improve if the game is to remain popular for years to come.

We recently released an article on the fun to be had racing GT2 and GT3 cars on-track at the same time. In fact, the two classes combine for fantastic racing on a variety of circuits. However, there was one part of the experience that felt lacking.

The article states that, at times, the Assetto Corsa Competizione AI can appear as if it were on train tracks. Following a very narrow racing line, rarely deviating. It does take away from the immersion of the title.

So with the game’s end of active life coming up fast and the Nordschleife soon to require greater AI use, surely it is time for an overhaul.

ACC: Problematic AI​

The issue does not limit itself to the blend of classes, nor does it only influence GT2 cars. Ever since the game’s release, it has seemed simplistic. As aforementioned, ACC AI does seem to follow the same line and stick to it in a very robotic way.

Furthermore, strange inputs such as brake dabbing mid-turn and a lack of confidence in door-to-door situations are a clear inheritance from the original Assetto Corsa. Elsewhere, random divebombs are not a rare occurrence in races, making for uninspiring fight-backs.

These race craft issues do not improve when it comes to multiclass racing. Confidence in traffic is lacking so long lines of faster cars unwilling to pass fill British GT content races. In addition, opponent strength does not seemingly mean much.

Pace from circuit to circuit and car to car does seem to be inconsistent. At times, 100% difficulty will be an easy win. Other times, dropping down to 95% will require a massive push to reach points-paying positions.

Finally, with offline race stints being limited to 30-minute driver time, accurate endurance simulations are complicated to complete in most game modes. Whilst it is possible to extend this in some cases, the feature does show signs that AI strategy is not up to par for a sportscar simulator. Poor performance and decision making in mixed conditions does not help the argument.

The result is an experience that lacks immersion in most cases. Whilst certainly serviceable, the experience of racing ACC AI will no doubt drive players away from the offline modes.

Time for a Fix​

Going further back, Kunos’ previous title does not exactly have industry-leading AI either. It seems offline racing is not the developer’s forte. But now is surely the time for change.

The modern racing game market is seeing a greater focus on AI development. Automobilista 2 received a major update last year to its AI’s strategic capabilities. Through the first month of 2024, the Brazilian title also saw its system become adept in race craft scenarios. Elsewhere, iRacing frequently adds to its offline racing library, an impressive experience in all scenarios.


Nurburgring Nordschleife Requires Top-Notch AI​

But perhaps the most important crunch time signal of them all is the upcoming addition of the Nordschleife to ACC. A tricky circuit layout with a variety of turns, the Green Hell demands a lot from sim racing AI systems. In addition, multiclass racing is the norm on the course. So the title will need greater capabilities in that respect if Kunos wants to satisfy the offline VLN fanatics.

The Green Hell in itself will require improvements to the ACC AI system. But it will also likely mark the end of active updates to the game. With Kunos moving attention to the upcoming Assetto Corsa 2, the online racing scene will no doubt suffer a decline. To keep the game alive, offline racing will be more crucial than ever.

The ability to run intense, competitive races offline years after the end of frequent updates will ensure ACC remains one of the greats. If all goes well, picture the sim alongside the likes of GTR2 and NASCAR 2003. If single player racing remains the tedious exercise it is today, a forgotten Project CARS scenario may be more likely.

If you call loud enough, maybe Marco hears you and keeps throwing money at Stefano until he comes back for a second time and gives the AI another shot.
 
Six years. SIX. YEARS. That's how long I've been begging for better AI in sim racing games. Nothing changed in these 6 years when I started simracing in 2017. Yes, AMS2 came out, we got more cars and tracks. But AI stayed as dumb as you can make it.

Us folks with lives outside gaming (jobs, families, you name it) don't have all day. Games are supposed to be fun, right? Yet here we are, stuck with abysmal AI that ruins the whole experience. You master the car, learn the track, crush the "max" difficulty... only to get smoked online by 2-6 seconds per lap. Talk about demotivating.


This is low-hanging fruit, people! Where's the innovation? GT7's Sophy AI is a glimmer of hope, but it has limited options.


Imagine it: you come home, 30-40 minutes to spare. You fire up your rig, pick your poison (car, track), and BOOM! An intense, close-fought race in your precious free time. It's a dream, right now.


So, developers, please hear our pleas! Give us AI that is actually fast, challenges, surprises, and makes sim racing truly shine for even the time-pressed players. We deserve it!
 
Did you watch endurance gt race? It's exactly like the ACC AI, fight at start of the race, then smal groups, with occasional overtake....

It doesn't need a major change, so there will be no more update on the AI.

The start could be improved, but won't be.

It's not a dream, just fire up rFactor2 with a right car/track combo.
I'm having a blast since the last year's AI updates, the bots are really lifelike, they will fight you like a real driver would do, they defend their position and overtake each other.

Pretty mind-blowing stuff if you find the time to tinker with the settings.

15 minutes tops if you know how to turn on the PC and know your way around Billie G's monopolistic environment.

Who needs AI! Racing against other people (pick-up races & leagues). Thats what I do. Offline is only a single player for making setups, notihng more. People are way more exciting to race against.
If nothing else, join here: https://www.thesimgrid.com/ races with other people almost every day.

But its true, also AI could be made way better then its now, thats for sure.

@Angus Martin., I respect your opinion on the AI subject, you have every right to find ACC AI uninspiring.
I might be wrong, but I believe, your main attraction to SIM, is racing online, so for me, only interested in Offline (done online for years) your perspective, like the one from @Mitja Bonca or others like you, will differ from my perspective.

I totally enjoy racing ACC AI, I also enjoy other game AI, like AMS2 (recently), RF2 (on some combo), AC ( on some combo), R3E (most of the time). AI, is a part of the attraction of (offline) SIM racing. Is AI reacting like real driver? No. Thanks god from my perspective.
I have no doubt that depending on if your are Offline or Online, or anywhere in-between, your tastes in AI and what makes them great to you, will vary wildly.
If I was a developer, I would make sure that my AI, pleases the Offline crowd, as what ever the AI does, as we have seen so far, no AI will replace Online racing, so choices have to be made.

Instead of everyone coming in this thread with answer like, "I prefer offline", "game (z) has the best ever AI ever" (because I like that SIM), I would be interested in a Poll, with people being able to express their opinion, in one of 3 categories, Mostly Online, Somewhere in Between, Mostly Offline, on their favorite AI, so we could have an idea on what AI most like better. Will not change anything on what we personally prefer, but would be interesting on what most like better.

Better, does not mean "perfect", my vote would go for ACC as a Mostly Offline, not because it is perfect in relation to my taste, just because, if I had to chose for an AI for all the title I enjoy ( yes more than one :)) it would be it.

@Angus Martin , which is your favorite AI?

ACC AI is competent, they don't crash into you or make silly moves most of the time. But they are boring, races in ACC are seldom exiting because they almost never make any mistakes, they never retire or have mechanical failures and the races are mainly boring processions.

I thought ACC was one of the sims that actually uses the same physics as the player, which should make it better? I did a bunch of AI races when getting my SR up for my LFM license and they were pretty dull. These days I generally find the AMS2 AI to be at the top, followed closely by iRacing. iRacing might actually be better, but AMS2 is much more fun to drive so wins out when I don't have time for online.
The problem with online racing isn't the time to race, it's the time to prepare. You really need to get to a certain level to not be a menace to others and to be competitive, and that takes time. If want to race an unfamiliar combo on AMS2 I can just drop the AI level to 80-85 until I get a bit more competent at that track/car combo and still have a fun race.

It is "robotic", yes, just like your typical endurance GT3 race.
Aggression settings increases chances of their racing line deviation, making rear ending when you are outclassed by much faster AI (if you skip quali) less likely.
Add to that that it drives on the same physics and cannot shift sideways or stop on a dime, and requires the same room as non AI car to react to changing situation, and you can make it work for you just fine.
Can it be better, sure, like any other sim AI, but even in the current state it is quite serviceable and if AC2 retains the same quality AI, I would not be disappointed.

EDIT: And if you want a taste of "bad AI", try FM23, I can assure you, it won't disappoint. :D

Yes, this. Exactly my thoughts.

All I need is AI behaviour with more variety and unpredictability, not robotic drones that maintain exactly the same pace from start to finish and never experience failures, mistakes, crashes and retirements. AI races are boring because there's no life to them.

This is a criticism of most sim racing titles, not just ACC.

I think back to how interesting races were in a game like Geoff Crammond's GP, and that was over 30 years ago.

ACC ai is better than AC ai, so I hope AC2 Ai will be better than ACC ai, just like the normal hope with a sequel, better than the previous one, not equal.
You have to up your standard and not accepte mediocre things.
It's with your acceptation that the devs are lazy, with low standard, the devs will give low quality.

Which physics the AI uses has little to do with their realism or performance. That's down to their programming. Some are good; most are not.

And any sim that can use the same physics as the player for many AI must have very unsophisticated physics for the player. No consumer-available computer today would be able to run multiple instances of good quality sim physics.

Let's hope that they finally focus 100% on AC2. Working on AI in ACC makes no sense to me, there are enough online servers always so what's the point and AC2 needs their focus now.
 
This is the reason I don't play ACC anymore. The AI is ridiculous! They bump you off the track and then continue to push you off with them following behind. In any case, I don't see the point in buying more content of playing, given AC2 is out this year.
 
a game focused on OFFLINE championships (ai, circuits, cars, full season, historically realistic) PLUS ONLINE mode: an excellent game.

a game focused on ONLINE racing (simplified AI, circuits, cars, full season??,...) PLUS OFFLINE mode: a mediocre game.

(although rfactor and AC are excellent simulators... they are practically made for online... even if there are mods with seasons of cars and circuits... they are unrealistic with the cars mixed together without taking into account how they were ordered in those years ...they are simulators only for "fast laps" and hotlaps, and "loose" races)

I don't have ACC, but knowing that it has that AI...from the beginning...makes me think it was made for online...and that's not a COMPLETE package. A complete package is built "backwards"...first the offline, and then the online.

Was always baffled by these "lazy developers" comments.
Developers just like anyone else are working within the constraints of budget, time, resources, material/engine, requirements, and sometimes, but much less often than someone might think, skills, which are easily acquired with some time and training. Of course there are raw talents like Stefano, who can sit down and revolutionize AI over few sleepless nights, but those are rare exceptions rather than the rule to the typical SW workforce. So saying that they are "lazy", is just a simpleton's view on the complex multi faceted thing like SW development.
What are you doing for a living, may I ask, is there a product that I can put my hands on and say, it's absolutely perfect, you have done a terrific job, nothing can possibly improve it?

I will say it. ACC, AC, RF2, AMS2, PC2 and the F1 series all have atrocious AI. Iracing, LFM, and RR all have atrocious human drivers(using the term human loosely).

The AI in any game is just a mirror of the all of the pretend drivers you get online. I have no more expectations of developers making perfect AI than I do that human will act like adults in online races
 
Who needs AI! Racing against other people (pick-up races & leagues). Thats what I do.
This is the worst take on a thread SPECIFICALLY about offline AI :roflmao: Sooo many people simply do not want to deal with the hassles of online racing, and offline AI has seen almost no advancements from any sim developer for so many years.
(no hate dude, and I appreciate all your fantastic AC mods!) :)

ACC AI is serviceable at 100% aggression but way too predictable and never challenge outside the 'desired' race line on corners. They simply give up, let you pass and fall in behind you. On a long enough straight they will occasionally attempt a pass, but that's about it. They're not smart enough to pass on corners nor set themselves up for the next corner.
