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.

Comments

Don't get me wrong, but I hope I am not the only person who found this dev update a bit underwhelming.

No, I think that's fair after this amount of time. There's a lot of improvements, updates and upgrades here but I'd understand if you were looking for a big 'mic drop' feature or looking forward to confirmation or previews of upcoming content.

For me, there's plenty here, a lot of the upcoming content is known (if not confirmed) and I'd rather they focus on improving what they have rather than adding something completely new, but I do understand if folk were looking for something else :)

I am cautiously optimistic about this update. Reiza worked wonders with AMS1, a fantastic display of what they are capable of. I have been disappointed with AMS2 to say the least. I will wait and see....please Reiza..knock this one out of the park. You can do it!

Mosport, Road Atlanta and Sebring are alone worth the wait for 1.6. Three fantastic tracks. RA and Mosport were only available as mods in other sims. To have them officially in AMS2 is awesome.
The bumps in the Sebring track surface esp the final turn are so damn good with great FFB
 
I can be wrong because I don't play all sim racing games on the market and don't drive all cars as well:D but when I read some comments about fantastic handling model of the other games mentioned above I wonder if they put huge aspect on tyres temperatures, presures etc.
AMS2 is not a simracing game where you start engine and have 200% grip from the start. It shows how important is to prepare operational temperature and utilizitation of tyres in the race.
If I'm wrong please correct me because I read some opinions that people who don't like AMS2 very often don't understand how this aspect works in real life. What can be saw in many lobbies even before first turn BTW;)

I remember playing AC for the first time (I choose Alfa as I am familiar with this car) and I said something like 'WTF oO' I know AC has huge fanbase but handling model is very poor or maybe I should say very simplistic (especially compared to PC2 in that time) and never come back to this game again for longer.

Hopefully there are so many simracing games that everyone will find something which consider as near the real life experience as he knows:) There is no need to trolling here, especially when many people write interesting comments and share tips related to article's title.

Personally I am waiting for next AMS2 update and keep my fingers crossed for Reiza:) It's amazing how this game changed over years.

Fun fact (maybe): I think we can all agree that AMS2 F1 driving experience is much better than in official game:D

It still is and always will be Ian's Bell aweful Madness Engine. No matter how many updates Reiza throws at this game engine...can't turn lead into gold. AMS, AC, ACC, R3E, rF2, Iracing, hell even Forza 5 and Gran Turismo. But anything that comes from Ian Bell...oh boy...toxic waste.

And this is why I know there's still years left in this project... And to not get excited by the rain... It looks nice, drives nice, but different for different cars on the track at the same time... When they fix the online and offline wet weather grip disparities then I'll be impressed...

Tyre wise they're always behind the 8 ball because of how badly the code was implemented in the first place... The rest of what has been done has been great, but the tyres have a long way to go and there's not a lot of room within the code to do it, hence Project Racing whatever is going to use the SETA 2...

This 1.6 is all about catching up in terms of thermal dynamics which has been around in every other tyre model code in a sim racing title for decades...

What's wrong with grip at wet surface?

Above I wrote few words about my feelings about tyre model. Don't make me wrong but which games did it better for decades? No offence, I really wonder because I don't play every sim on the market but these I am familiar with are not quite realistic in such terms and other (like GT) are great... decades ago.

I read many complains but almost nobody use arguments other than: 'trust me bro';)
Give me some details and comparision if it's not a problem please.

Nice joke. I never like Forza so I won't comment but Gran Turismo is in fact the same game since PSX era. The last one is the biggest joke in the series only because Sport is focused on online. I don't understand why you wrote about these game in this topic anyway but statement they are better SIMS than PC2 or AMS2 surpasses our understanding of the world in which we live:D

I can clearly say I'm done reading this trolling. It's pointless and waste of time.

It's a shame because articles on Overtake.gg are really good as well as comments of some people on forum.

There is the option to "ignore" in this forum. Although I don't use it, it could help you.

Im always so glad when you post on AMS2 articles. Your input has been so important since the day it was incepted. Thank you Boby Kim, hopefully everyone that has been enjoying AMS2 can remember your wise words next time they even think about loading it up.

I don't ignore people or use such options. It's stupid. We all take responsibility for what we write or say and in my opinion you are trolling writing about Forza and Gran Turismo in topic of AMS2. If you read carefully you will notice I do not say anything about your opinion about Madness Engine or other simracing titles because they are somehow related to the subject.
Maybe you should think twice next time instead play a victim? Take it like a man or just answer a question.

Edit: I'm sorry Alexandre because you are not the author of the post I answered. You found yourself between a rock and a hard place of your own making;) However I think my explanation is more than clear.

"A secondary stage of the overhaul will take place next year and will delve deeper into the rendering engine in pursuit of further improvements, with anti-aliasing and shadow casting development being prime targets."

see you next year, for the shadows and anti aliasing fix:thumbsup:😂
I think I hate more the aliased shadows than the driving feeling.
hate is something you definely know a lot

please make a youtube tutorial for us on how to be a hater I'll watch and give it a like

Yeah he's talking rubbish. All the sims update their tyre model periodically. iRacing does it, and has a new update in the works, ACC did it a while back, so did Raceroom. None of them have had it right straight out of the block, because its an incredibly complicated thing to get right in a sim. RF2/LMU are not perfect either before the "rf2 is god" people show up.

No worries. I agree that ignoring is stupid, that's why I don't do that. I was just saying that's an option.

Exactly! I love your comment! It's a pure strenght of the arguments and explanation I'm waiting for! Thank you!
 
Those of us with beta access are very much grinning with what is coming. But if you don't like AMS2 after this next update then you probably never will. AMS2 is the only sim that gives me a majority of what I want even though it is not perfect, yet. Reiza still gave a lot they want to do with AMS2 and I have no doubt that with their talents they will get there in the end.

Yes, I realized it after noticed who was an author of the original post. I'm happy we are agree in matter of blocking/ignoring:)
I'm really sorry once again for a mistake and I'm glad you passed by it.
Cheers!
