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.

I wish they toned things down a bit, like the vapour trails are quite exaggerated, and also, when we watch wet races on TV your can't see the rain coming down like that as you can with these previews. It's almost like you can see every streak/droplet of rain coming down, if they made them a bit more transparent it would look a bit more realistic.

I get what you are saying, but if they did that, you'd have someone saying "I can't notice it, we need it to be more obvious". They won't be able to please everyone. Some people don't like the way the game looks and that's fine, personally I prefer it to most of the others, graphically.
 
lovely update coming!

one thing I really want to have is to be able to reduce HUD size as can be done in AC Competizione.
You mean scaling particular elements? I'm sorry for dumb question but I am unfamiliar with ACC. If so, then I agree it could be a very nice feature even if I don't use HUD.

My biggest problem with menu/car settings UI is weird responsiveness of elements when using a mouse. Especially when I want tweak car setting as fast as possible. With controller (gamepad or wheel buttons) it works great like in PC2.

Really looking forward to this update. The AI improvements seem quite good. I did play a lot of quick races with the modern F1 car and while it was one of the better if not best F1 AI experience in modern sims, something was missing, especially AI cars attacking properly. It seems to be much improved from that video.

Forget TV, how does it compare to what you see when it's raining outside with your own eyes?
 
One thing I hope they fix is AI straight-line speed. Currently in my experience if you have a better exit coming out of a corner than an AI in the same car they'll still overtake you on the straight.
 
cant wait to test it, and after 1min, feeling badly simcade, then go back to serious sim or my lovely the crew motorfest :D, AMS 2 is not enough high standard to be a pure sim like rF2/LMU/racerom/iRacing, and not enough fun and arcade like the crew mortorfest, I have no place for this game :D

I like how Overtake posted this alongside the LMU update, the trolls are going to have to multitask or choose which one they hate most:)
Usually AMS2 haters show on every Reiza related post but I didn't see any AMS2 lover spreading hate on others platforms....maybe reacting to be called "fanboys" but not bashing others just for their agenda...

I am sorry to say this but AMS2 isn't a very realistic looking sim in any way. This begins from what I see from the cockpit - it looks a bit like a Michael Bay movie - and ends with what is shown in the replays. Unless you use a trackside spector mode, but replays generaly show what you would see on your TV and should be the target if leagues plan on broadcasting their races. I remember when S397 updated their wet weather graphics scaling of the rain drops was wrong aswell and they fixed it. And given how the Madness engine is known for it's visual fidelity, I was a bit shocked by the Spa replay because everything about it looks off. Those marbles that don't seem to fit into the scene at all aren't any better. There is no denying that iRacing is doing a perfect job in that regard and that's where the benchmark is for any sim out there.

That said, I am more looking forward to how AI works in multiclass AI races and how the physics improvements turn out.
