Automobilista 2 is set to take another big step with its incoming update to v1.6. Developer Reiza Studios shared another look into the new version with their latest dev blog.

UPDATED September 17, 19:10 UTC

It had been a while since Reiza Studios gave an update on how version 1.6 of Automobilista 2 is progressing. The latest dev update had been released in May, with more to follow before the release of the actual update. One of the new dev updates is now here, and Automobilista 2 v1.6 does not seem far off anymore. The 'Road to v1.6 Pt2" post details several elements that will improve the sim.

Of course, these are only part of the bigger picture for AMS2. In May, Reiza already highlighted the reworked LMDh/GTP hybrid system, which is going to work like the real counterpart from v1.6 onwards, as well as reworked smoke shaders to improve the look of engine failures.

Physics​

The centerpiece of the update - although it is hard to limit that term to just one element - are the improved physics. Showcased already in the 2024 Brazilian Stock Car Pro vehicles and F-Ultimate Gen 2 cars, all cars in the sim will feel different and much more cohesive once v1.6 rolls around, Reiza promises.

Studio Founder and CEO Renato Simioni states that "there is understandable skepticism around the term "game-changing" when it comes to physics development, but there are changes that quite literally fundamentally transform many of these intertwined dynamics, without necesarily eliminating the work that came before".

The physics changes are mainly driven by "development of tire hysteresis along with a tire thermodynamics overhaul. Brake have also received a thermodynamics overhaul of their ownand have a much more tangible feel to them", details the dev update.

Refined AI Behavior​


Now September rapidly advances, the Brazilian studio showed more previews, with the AI racing in the sim being the main focus. A short race at Monzain AMS2's version of a current-gen Formula One car, called the F-Ultimate Gen 2 in the game, highlights the reworked behavior of the computer-controlled opponents. They appear to be less frantic, more considerate but not shy to go for overtakes or defensive moves either.

Nine areas in which the AI has been improved are mentioned in particular:

  • AI will now move more decisively to cover the inside line to protect position from an attacking car
  • AI will prioritize taking the inside line of the next braking zone in order to complete a manouver succesfully (rather than just go wherever there is more space as it used to be)
  • AI will move over and lift when appropriate to give way to faster cars when under blue flag
  • AI will actively try to create space between themselves and nearby cars when opening a hotlap in practice / qualifying
  • AI will gauge slower traffic way further ahead than before in order to decide the best course of action navigating it
  • Further elaboration of pitstop logic to increase chances of sound AI pit strategy even in longer races
  • AI is far less constrained with regards to where it places itself on the track relative to other cars and the racing line itself, allowing it far more freedom to complete overtaking moves
  • At the same time AI will be far less inclined to conclude exceeding track boundaries is necessary to avoid an incident, and will suffer more consequences in terms of time lost if and when it does so
  • AI Aggresion setting is more influential in defining agressive behavior from the AI

Additionally, the AI received more adjustments for running in the wet and dry (and conditions somewhere in between), "mitigating most if not all persisting discrepancies in performance".

Multiplayer Sees "Substantial Improvements To The Netcode"​

Not exactly a strong suit of AMS2 so far, the sim's multiplayer - like pretty much every other area of the title - has received significant attention. This resulted in significant improvements related to its netcode, the abilities to share setups easier, and the ability to join servers closer towards the end of qualifying.

The netcode changes in particular have apparently given encouraging results when tested with third-party competition platforms - the achilles heel of AMS2's multiplayer thus far.

Progress With Racing In The Rain​


Another element that had already been touched upon in the previous bigger update to v1.5 is racing in the wet. While a slight loss of grip was already noticeable on the dry racing line once the track turned wet, this effect will be more noticeable in v1.6, with the visuals to match.

The rubbered-in racing line from running in the dry will look different and more shiny than the rest of the track. Adapting your line throughout the turns to find more grip off of the usual racing line will be more important as a result.

Additionally, the way water spray looks like is adjusted, and certain rainy scenarios will not look mostly gray anymore, as the demonstration video shows a mostly cloudy Spa in circa 1993, with the sun occasionally peeking through the clouds.

Humidity Modelling​


The weather system in AMS2 will see more refinement even in the dry, too. Remember that epic battle Ayrton Senna and Nigel Mansell had at the 1991 Spanish Grand Prix? As they raced down the main straight side by side, sparks were flying off the cars - and those characteristic vortices formed on the edges of both cars' rear wings.

This will make its way into Automobilista 2 via version 1.6, too. The sim will take humidity into account more, and relatively cold temperatures coupled with high humidity and race cars with big rear wings will then result in those vortices forming. A neat little detail that could make for some excellent screenshots.

Increased Grid Sizes​

Automobilista 2's 32-car grid limit has been a gripe for a number of sim racers, particularly for offline racers who wanted more crowded race tracks. The v1.6 update will up that limit to 48 vehicles - if you got 12 Gb or more of physical memory available. Online, the 32-car limit remains in place.

Of course, a track needs to support this many grid slots - so if you were hoping to run 48 cars at Cadwell Park, you might be disappointed.

Graphics Overhaul​

Already mentioned in the May dev update, AMS2 will look different once the update to v1.6 is out, too. Several shaders have been improved - like the aforementioned spray in the rain - and a more natural depiction of cars and tracks in a variety of weather conditions and lighting scenarios are the result. Crucially, this has been achieved with a "negligible performance impact".

Added eye candy include dynamic exhausts that glow depending on how hot they get, trackside fireworks, more 3D trees that even get wet at many tracks, and more.

More To Come​

Additional dev updates are set to follow Pt2 soon, with more previews on the way "over the next few days to get hearts pumping", according to the new dev update. Audio development is set to feature in this, as well as more spotlight on the incoming content.

And this explains why it gets a lot of heat...

If it's so different, how was it so realistic last year after 1.5 when that makes the current public build look very good...?

Makes choosing who to trust out of the BETA and interesting task...
Every sim reckons it is a lot more realistic after a major update, or at least the fans of it do and the non fans don't, ACC did major tyre remodelling, isn't iracing always working on that? I have seen changelogs for LMU that I am pretty sure also mentioned tyre updates.

None of these sims are the same as they were on day 1 so should we say none of them were realistic?

At the end of the day it all comes down to interpretation of what is real and what isn't and how the userbase reacts to it. If you don't like it just move to another sim. I stopped playing rf2 years ago because as a package it just isn't appealing to me. The driving physics were the only part that was enjoyable but I want more than that out of a sim, I want to be able to do single player championships and not just single races for example.
I have heard stories of one real life racer saying a certain sim is very realistic and another say it is nothing like the real thing, who do we believe?

The great thing is we have choice, like it play it, don't like it don't play it. Just play whatever floats your boat. Everyone will be able to decide for themselves soon enough.
 
In it's correct form the scientific version is advanced... And works very well for road tyres...

What has been implemented in the Madness engine hasn't been that advanced and as Reiza has shown has been hard to tune and until last year was heavily bugged... Might take them another year or 2 to get all of the warts out and bring out it's full potential...
Just see what you think when the new update drops but I think people will generally be surprised at how much tighter it is.
 
When it's wet for one person and completely dry for another person...

It's like when the AI completely ignores puddles, but randomly different from driver to driver online...



All of them, it's nothing new, it's one of the reasons iRacing gets it's "ICERacing" tag...

Too much thermal stress on the IR tyre and it turns to butter... Not hot enough and there's not enough grip and it feels like Ice...

That's what thermal issues are all about... And thermal issues are the headline for the 1.6 tyre update...

The SETA tyre has always done thermal issues in the most basic sense... The brakes in the Madness engine have been long overdue an overhaul as well... So in theory the cars in AMS2 1.6 should be a lot harder to drive out of the pits with everything cold with the upgrades...
Thank you for answer especially regarding to iRacing as I never play it myself.

When it comes to AMS2 I don't notice such problems playing online but it's difficult for me to say you are wrong. Most network engines have similar issues (I don't talk about racing games now but in general).

When it comes to the tyre model I have the same feeling and wrote about it so we are agree here (maybe I won't be clear enough). And yes, new update looks promising but if I'm correct some of the features in AMS2 exists before but are not as exposed as they will be. I read about it some time ago on Reiza forum.

And like @F1Aussie mentioned all sim-racing games evolved. AMS2 at least inherited good tire model and makes its great. Now it's time to push it on another level of greatness. I really don't understand why it's so much criticized but as we exchanged our opinions, I think there is no point in going any further. Neither of us will convince the other.

However, I consider the interesting facts valuable.

I would say the cars ARE harder to drive in 1.6, especially on cold tyres for the first few laps, the difference is much more noticeable in 1.6 than the current live release, and compared to other games ( AC for example, I think I barely notice it at all, LMU its noticeable ). Personally, it feels more in line with iRacing to me, but with better FFB and much better graphics. I'll take that.
 
Looking forward to AI updates the most. AMS2 isn't my go-to sim on a wheel, but it's great on Steam deck when my wheel's not available or just too tired to sit at it.

And while the AI is solid most of the time, they're a bit predictable, don't cover the inside line very well, and can get pretty rough when trying to stay on their line. So really curious to see how they feel after this update!
 
One of my biggest bugbears about the old menus was how you could hover over certain elements and they weren't recognised you had to move away from them and then go back to them.
That's my biggest issue with the current AMS2 UI. Not the looks, etc, but the bugs of it. What you said is especially felt in the car settings. Has this been fixed in the new UI?
 
This level of eliticism (for which you have to pay at that) is pretty sad.
Well, as I fully agree about poor practices on todays gaming market when we are often testers for our own money or paying big money for so called 'early access' I think companies demand NDA to sign anyway. It's up to people if they accept it or not.

I have no idea if gamers like @F1Aussie must pay for this elitism like you call it (because I'm ignorant in this particular subject) but I can understand Reiza want build hype before release.
Let's be honest, with all my love to AMS2 this title is very often on sale and if they not sell expected amount of 'copies' then we can forget about new tracks and cars as it takes probably huge amount of money and working hours to make for example Le Mans DLC.

I don't like such approach in modern gaming industry, prefer GOG.com over Steam and other digital crap when it comes to PC (consoles aren't better) but gaming in general is not the same like 30 yrs ago. We have almost nothing to say in many aspects especially when almost everyone is a gamer now.

If @F1Aussie don't want to say about it straith then it means:
1. He can't because of NDA.
2. Likes joking (I found it funny in a positive manner).
3. He gives you answer already between lines and this aspect is repaired (Reiza rebuild GUI because many complains).

You can always ask at their forum. Renato or other member probably gives you answer.

Really sad thing will be if woke idiots come with their dirty shoes to the sim-racing genre. Let's wait for the first reviews. I own all DLCs to AMS2 but don't open wallet before I'm not sure what to expect. This update seems to be huge so few days don't change much.

Few forum users including @F1Aussie said it will be something bigger than before.

However, it will be nice to have a clear answer as issue you mentioned is really annoying and I don't think it will be a big deal to share with community if it's fixed, beacuse in a fact devs presented much more important things already.

And I don't protect weak practices for your information. I'm not a 'fanboy' qnd I think I'm quite aware customer/consumer.

In general I agree it's sad but probably for a reason.

Cheers!

EDIT: I wonder if someone will read this from beginning to the end:D

For the sake of clarity: AMS2 Beta users are not users who bought the additional "honour" to be a Beta tester. They are people who have bought at a discounted but anticipated price the whole future content to be released in the sim without knowledge of what that will be, just on the faith that Reiza will deliver that much content worth of our money and interest.
There are things we just cannot say as per Reiza Beta policy. We have not signed any NDA other than abide by the policy.
In facts most of the Beta testers participate because of the passion for the sim, not because of elitism.

At first thank you for explanation MadDriver11.

As I said I'm ignorant in some subjects so excuse me speculation but that's what I understand from @Havner comment. It doesn't mean I don't agree with him in much more deep aspect but it's related to the game industry as a whole (I go too far into offtopic as a result - shame on me).

Belive me I have big faith in Reiza (especially because they continue my dream about simracing game tailored to my personal taste). I bought Automobilista 2, next it was Season Pass 2020-2022 if I remember correctly, USA Expansion Packs not as a full packet but every part separately, same with historical and supercars DLCs. I have them all but it seems I must miss something. Whatever as it change completely nothing in my life and I am happy some people can enjoy new features and probably help to develop the game in right direction.

The Beta Policy or NDA is something normal and there is no need to be nervous when someone mentioned about it. Normal practice.

Hovewer I don't know why you think me or other people who do not participate as a beta testers have no passion for the simracing or AMS2 in such case. It clearly shows you feels 'somehow special' and in fact this is sad (attitude) and contradictory to what you wrote:

Beta testers participate because of the passion for the sim, not because of elitism.
It's far from logic when you used this sentence.

@F1Aussie behaved in a civilized and funny way. I would appreciate if you didn't compare us to the plebs, because we also support the project with our money and a few sentences could have been avoided here from your side. I don't care much about myself but other AMS2 fans.

Thank you in advance for considering above for the future and once again thank you for explanation how it works. That's why I gave you 'like' despite some unnecessary words.

Cheers!

Never said others do not have passion. Maybe they just weren't aware of the possibility or just couldn't or wouldn't pay upfront that money. I can say for sure those who did participate do have a lot of passion for the sim.

Your logic is very strange since you think that people who are not wealthy and save every penny to buy a game (I'm not even talking about expensive accessories, because that's often beyond their reach) and thus support the creators are less passionate than those who can afford it. I think that this poorer group can call themselves true enthusiasts because they give up many things in the name of their hobby. I don't know you, but you seem to live in a bubble. However, if that suits you, then I have no problem with that.

I refer to the statement:
just couldn't pay (...) those who did participate do have a lot of passion for the sim.

The rest is correct. I never said it's not:)

Reiza representatives would certainly be happy to have such a person in the PR department:D Success is guaranteed:D

I'm sorry but it's too funny to read such things:D You can contradict yourself in one sentence and not even notice it:D

Period.
 
The buy in beta program allowed those of us who wanted to, to buy in to get all future content without having to pay again, it also gave us access to the beta so we could play it, if we want to and provide feedback to help develop it.
There is nothing elistist to it, not sure where that would come from or why someone would think that.
We cannot just blurt out what is in development or what new content there is, that would also be a betrayal of Reizas trust. Out of all the Sims I have played over the years I have never come across a developer as open and communicative as Reiza, we are blessed to have them working in an industry that we have a hobby in.

They also listen to users feedback and take it on board. For example,i asked about if something could be implemented, and I am sure I am not the only one who asked but a couple of beta builds later and it was in.

You are completely inventing a meaning in my words that is not there: I only said that the guys who joined in Beta are not there because they want to be part of an elite. They are there for their passion.
This does NOT equal to saying that everyone else does not have passion.
Kindly stop putting in my mouth words I've never spoken.
Thanks
