Automobilista 2: Patch 1.6.3.6 Adjusts AI Fuel Parameters

Automobilista 2 Hotfix 1.6.3.6.jpg
A new patch for Automobilista 2 has arrived: V1.6.3.6 mostly addresses AI fuel parameters that affected their strategy, but also fixes and recalibrates a number of other elements.

With more frequent updates on the horizon in 2025 compared to the previous year, Reiza Studios has released what should be the final small update of the v1.6 development cycle of Automobilista 2.

Several sim racers had noticed AI drivers not being able to handle Daytona's turn one - the road course variant, that is - all that well, often crashing into the inside wall. The patch should prevent this, at least most of the time - just like it should keep the AI from making weird pit stop strategy decisions. Furthermore, a few classes have received performance calibrations, while Reiza has also fixed some minor visual errors as well as the ARC Camaro being unable to start its engine since the most recent update.

Other minor changes concern the tire treads of all karts plus ten further classes. You can find the full extent of the changes in the patch notes below.

Automobilista 2 v1.6.3.6 Changelog​

UI & HUD

  • Updated names & logos for Karting classes
  • Fixed missing leaderboard class colours for both LMP2 gens

PHYSICS

  • Further minor tire tread adjustments to karts, LMDh/GTP, LMP2, P1 (both gens), F-Ultimate Gen2, Copa Classics, ARC Camaro, Caterham 620R, Superlight & Supersport
  • F-Ultimate Gen2: Further throttle map update
  • Fixed player control issues with F-USA Lola Gen2 & Gen3 oval variants
  • ARC Camaro Fixed issue with engine not running
  • Minor tread thermodynamic adjustments to kart tires
  • Corrected further inconsistencies in F-USA Gen2 & Gen2 Lola oval variants
  • Disabled redundant rear toe rang for karts
  • Increased draft effect to ramp from 100m (over previous 75m)

AI

  • Adjusted AI pitstop estimate losses & tire wear thresholds for all Endurance classes & F-USA oval variants so AI drivers in those classes are generaly less likely to find pitstops worthwhile until it is running low on fuel
  • Reduced amount of extra fuel AI will carry as a safety margin in qualifying & last stint of races
  • Reduced fuel safety margin threshold under which AI will pit for fuel in races
  • Reduced amount of fuel AI carries when fuel consumption is disabled

  • Adjusted AI corridors at Daytona road courses to minimise chances of AI hitting the inside wall going into T1
  • AI tire wear calibration pass for LMDh, GT3 (both gens), GT4, GT Open, GT1, Group C
  • AI dry performance calibration pass for Copa Classic, Caterham Supersport, Caterha, Superlight, ARC Camaro
  • Further adjustments to mitigate chances of AI karts rolling under hard cornering

AUDIO

  • Cadillac V-Series R: removed fresnel mapping to external carbon material

Just prior to the hotfix, Reiza Founder and Lead Developer Renato Simioni has revealed that Automobilista 2 will see more frequent updates throughout 2025, which will include new content "pretty much every month". Furthermore, new features will also be introduced to spice up race weekends and make players reconsider how they approach a session.

One thing I've noticed is if you do an offline championship you can't skip qualifying so you have to sit through the whole session length which tbh is stupid.
 
On the Steam update they lead with: 'We've extended the cycle' what cycle? You're the only ones making decisions about what makes it into a patch and when patches will happen. There was absolutely no reason to say the last patch wouldn't be iterated on for some time. And at the same time giving interviews about how this year there's definitely going to be new content every month! Again I am pleading with Reiza to hire a professional communications manager because Renato is a very talented, accomplished and passionate individual but he is terrible at this stuff.
 
Based on which data they are constantly adjusting tires? In each update tires gets adjusted for numerous vehicles. Go figure.
And karting is still terible, one of the worst there ever was in games. Btw, when I was living in Brazil, I was numerous of times on karting track Granja Viana, and AMS2 misses lots of layouts, which existed back then (15yrs ago), and I belive they still exist.

So last week I tried out the karts for the first time in ages and was pleasantly surprised a) how well they handle compared to before and b) how well the AI finally gets to grips with them. It's a big plus for me and I can't quite understand the criticism, but to each his own.
 
Name one dev which isn't further adjusting and improving their sim as long as it's still alive and taken care of. :coffee:
I mean you are right, it just doesn't sit well when Reiza officially as well as their hardcore fanbase attacked Jimmy Broadbent when he criticized their physics as not being very realistic in many scenarios a couple years ago. How many "game changing" physics revisions came out since? Like every major version update with constant tweaks in minor updates...

And I am not saying that it is wrong to tweak, I welcome it, but often statements and patch notes are not very compatible with each other. Not to mention this constant tweaking is probably playing at least a minor role in AI problems that just keep coming.

Major changes probably cause issues with the AI. It happened to Raceroom with the last tire model update, fully braking its tremendous AI. And that probably explains why Renato stated that they had to wait to stabilize the core of the game before fully revising the AI, and why these adjustments are considered minor, they probably don't critically impact the AI. But I'm only making, quiet logical, assumptions.
 
What needs to be fix is the FFB off track, on grass and gravel : nothing happens, you just lose connection with the ground. I wasn't aware of that bug before a youtuber spoke about it and I fully confirm, I've checked.

On one hand the idea of continuous improvement seems great, but in practice all of this feels like early access problems for sims that have been released, in the case of RaceRoom, for more than a decade. Folks on ACE threads are worried about online functionality breaking it when it reaches end of life, meanwhile we have "offline" sims that have certain aspects broken due to core changes. ACC is a prime example, as the latest physics update also screwed the AI, and for that I am afraid, we won't be getting a fix.

He was actually quite rude, disparaging and arrogant IMO. I get why the devs or the people involved bit back as they are sitting there grinding away at code trying to make a fantastic product which was still in its early stages of development and people like Jimmy Broadbent have a platform which can have seriously negative impacts to a products appeal or reputation to the market.

IMO Jimmy should have thought about how he reported on AMS2, as he then also made public private communications in a way that fitted whatever warped narrative he is aligned too.

Jimmy Broadbent and all of his ilk (especially that melt Kireth) are stealing a living. I have it on very good authority that they get paid quite well by certain studios for overly positive and forgiving reporting on various titles.

Jimmy Broadbent is a shill to the grandest scale.

So was it great back then or not? If yes, why the physics revisions? If not, why the reactions?

Reiza, S397, KW, Kunos, SMS, ISI, EA, and whoever I missed, are selling commercial products. When you are in early access, it's all right to give some slack. When you are in full release and also selling DLCs, subscriptions, etc., there is no such thing as "oh my poor little studio, they are working so hard, please don't hurt them". You sell something for money then be ready to recieve feedback, good and bad. Jimmy gave AMS2 good feedback (immersion, performance, graphics) and bad feedback (physics). Just like with every sim and game. Of course everybody has their own priority list and it's only honest to give opinions based on that (incl. me with AI ranting). Is he most frequently on iRacing? Yes. Did he criticize the LMHs, M4 GT4 that he drives IRL, yes, even clearly preferred the R3E handling. Does he have issues with LMU? Yes. Does he acknowledge that it's a lot of fun and recommends it? Yes. I don't see that terrible shillness anywhere. And accusing people without providing evidence is not a very nice thing to do, you wouldn't want to be on that side either...

Firstly I completely agree with your comments about Jimmy... I may have zero time for tubers as it's just not my thing, however that whole situation was deplorable customer service and just further led into the toxic behaviour that has often been talked about here over the years even right back to 2022 when I was first warned about these tirades...

THIS 1000 TIMES THIS...!!!

So many people, especially one simmers, carry on like their favourite developer is at best a football team and at worst a charity... Where you can't dare criticize their work you should be down talked and treated like trash if you dare say anything negative... This defensive behaviour is the root cause of the toxic sim racing conversations that go on for ever... Those who act like this are the true shills in sim racing...

It's a company focused on profits... Not something they are doing out of their own free time... That's what a modder is... Some people forget that...

Downloaded, tested it. Unfortunately still can't race the LMDH against the AI at Daytona, they still can't go thru bus stop. Shame.

Hope the fuel thing is fixed, will test later

Trust me, karts in AMS2 are driving no where near what RL karts drive. I don't even know whats wrong, but its everything, its a mix of wrongness all around. Maybe good for someone who has never driven a racing kart, but not for me.

And about the constant tire updates: no other dev adjust it as often as Reiza does, not even close, at least not in sim worlds like iR, AC, ACC, rF2, LMU and RR (else its not worth mentioning). Adjusting tire physics most often means setups made from scratch - which we don't like, right? At least I don't. Spending hours and hours on a particular setup, then new tire update arrives and boom, old setup is no good anymore. No thx Reiza.

The problem with Jimmy back then was (for me) not that he criticized the game, as it had clear flaws in how it drove and has come a long way since then. He was out in force to lambast, exaggerating every single detail of thr game, at points with a diametrically opposite view of what was actually happening in game (like having a sudden snap that he quickly corrected, and then blaming the car for being too soft LOL). It was quite obvious that he had a personal agenda, specially when it surfaced that back in 2022 Reiza, unlike other devs, was not paying any influencers nor media for generating content about their games (pretty sure that's not the case anymore, given the bigger influx of content about AMS2 seen since 1.5 release in July 2023).

Now, the "game changer" tag is something that has been overused by users, and maybe some content creators in past updates, for reasons I don't agree with. But Reiza themselves? They only did it for the 1.6 public release. They have questionable methods for public relations, but they also get attributed every single thing said by the users as if coming from them directly, which is not true.

Finally, I will say that I completely agree with you about physics development. It makes everything else a moving target. They have reached a point of maturity which, besides minor tweaks that will keep on happening as it's part of the polishing process, it's enough. It's time to shift focus towards the rest of the game and round it up. Which according to the last articles seen here, it's what will happen from now on. I hope it's the case. But besides the racing features and the AI improvements, there are two things I want: one is a revision of the game's default settings to remove the floaty effect given by cameras. The other is a full default setup revamp, adding more starting options per car, and doing away once and for all with the stupid logic of making a car understeer like mad for a start, but with little rear grip so it can oversteer if provoked enough. It may have been good for 1.4 updates, but by now it's long in the tooth and the more peaky physics render them useless. And as more and more simracers have less and less setup building knowledge, it's a bigger and bigger shot in the foot.

Hm,i can't confirm this.Are you useing "custom AI files" or play a different game as i do....:thumbsdown:

Overtake. Where all the forum users that got butt hurt by Renato go to bash the game because they feel it's their personal mission to share their dissatisfaction with the world. Renato lives in their head. It's entertaining to say the least.
