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.

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.
They did fantastic work for all these years. I miss some minor things like collisions in a pitlane, snow and other features from PC2 but it's hard to demand wonders. More important for me is Reiza as independent deveper because a repeat of the chase for corporate money (SMS) will take away next simracing game from the market forever. If someone like it or not it would be a huge miss.

BTW I love tracks from South America. Maybe they are not spectacular and well known but as a person from Europe I like to know something more than Interlagos;) With changes in F1 calendar maybe we can see Sochi or Paul Ricard in a future.

It's a little shame the tracks from PC2 are not fully compatible because modders did a great job to port them (same with cars).

Let's wait and see what next years brings to fans:)

I'm a little jealous of your access to the beta:p

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.

My friend, this pz666 is a known AMS2 troll. He goes everywhere and flaps his lips and no one listens. Just hit the ignore button and be done with his worthless posts.

And to put some value in this post, also being on the beta I can say... you are in for a treat when 1.6 releases.

I wasn't a believer until a couple of days ago when I decided to give the beta a chance and omg, some stuff is day/night difference.

I don't like the new menus thou. They look kinda amateurish to me, but I couldn't care less about them. The driving feel is awesome, and the new content is amazing.

I can't comment on anything like that as in notformedia branch, but I hear you. :)
