Automobilista 2 V1.6.4.2 is now live - this update introduces Super Trophy Trucks with the new Adrenaline Pt2 DLC along with several other fixes and improvements.

Adrenaline Pt2 is available for purchase here, but as is customary it will remain free for all users over the next couple of days.

If by any chance you encounter issues with this build, the previous V1.6.3.6 remains available as a Beta Branch on Steam ("previousbuild")

As part of a series of optimization measures taken for this update, the physics engine now runs on four CPU threads by default instead of the previous default of two; this however might not be a net positive for users running substantially older systems, if that is your case you may revert to the old standard by running the command line -pthreads 2


CONTENT

• Added Super Trophy Truck series & 12 dedicated STT layouts (part of Adrenaline Pt2 DLC)

GENERAL

• Added 48-max grid size support for Championship mode (requires minimum 12GB RAM)
  
• Fixed issue where requesting a pitstop via the ICM menu would fail in some cases
  
• Revised LiveTrack rubber laydown to better reflect current tire load and slip and reduce differences between player and AI vehicles
  
• Replaced all instant DQs from formation lap and rolling start infringements with drive-through penalties
  
• Removed start light countdown in rolling starts to make green light less predictable (lights now go from all red directly to green)
  
• Corrected penalties being awarded while the AI is in control of player car during rolling start, formation laps, and in auto rolling start modes
  
• Fixed issue where fuel wouldn't be added to the player vehicle during a pitstop when the rules allowed refuel and the player had a fuel value set in the strategy
  
• Fixed particles producing jagged edges around geometry when using lower particle detail settings
  
• Performance optimization on CPU-render logic related to environment maps.
  
• FFB loop optimization pass
  
• Physics now default to running in 4 CPU treads instead of previous 2

UI & HUD

• Separated 'Suspension' from 'Mechanical' and added a new 'Aero+Suspension' option for pit strategy repair shortcuts of ICM menu to allow repair without the lengthy cost of brake/engine replacement
  
• Fixed non-karting presets incorrectly listing kart layoutts; Excluded Oval / Dirt / Kart layouts from listing in ARC Camaro & F-Inter presets

• Mercedes EVO2 DTM Gr.A: Corrected error in rear left tire pressure setting
  
• Lotus 23: Reduced rear brake cooling
  
• Audi R8 GT4: Revised FFB

AI

• Adjusted AI behaviour so that if it runs into another car and is held up in the first or second sector of a hotlap in practice or qualifying, it may either re-engage outlap behavior to open a gap for another hot lap or return to pits (if late into its stint)
  
• Adjusted logic which AI drivers follow when leaving pits in practice & qualifying to minimise issues with intense traffic early on the sessions
  
• Added AI Wet Skill Scalar and AI Mistake Multiplier options to championship overview screen
  
• General calibration pas to AI performance losses with cold tires particularly under cold environment temperatures
  
• Calibrated AI simulated session times for F-USA Gen1 & Gen2 (all variants)
  
• ARC Camaro: AI calibration pass; further adjustment to prevent AI cars from rolling when hitting high curbs
  
• Brabham BT46: Adjusted AI undertrayd physics to mitigate lower performance vs player in this car
  
• F-USA (All Gens): Calibrated AI simulated session times
  
• AI calibration pass for Super V8, Copa Montana, GT4

AUDIO

• Changed "Opponent Samples" option to "Sound Detail" as it now also affects environmental effects
  
• Fixed trackside and chase cam engine sound pitch for Stock Car Brazil 2019 and Metalmoro AJR Chevrolet V8

Greetings Everyone!

We have a new update incoming for AMS2, and as hinted upon on the run-up to V1.6 release late last year our dev updates will now be focused on covering the highlights of these upcoming releases, which you should be able to check out for yourself very soon!

So here are some of the highlights of the upcoming AMS2 V1.6.4 to be deployed in time for the weekend!

On the content front it´s time for another shot of Adrenaline with the introduction of one of the most extravagant forms of motorsports ever seen any time, anywhere - the Super Trophy Trucks in AMS2 (like the Supertrucks in AMS1 before it) are loosely inspired by the Stadium SuperTrucks series in America, with Trucks weighing 1400kg delivering over 600 HP hustling through road and street courses filled with jumping ramps making for some insane air time and spectacular action; when shooting off corners these beasts can lift the inside front wheel clear off the ground and keep it there until the next corner, especially the left front wheel aided by the roll direction of the engine.
We have spent a lot of time and efforts into doing justice to these crazy machines and the unique experience racing them provides; they are like nothing you have ever experienced in a racing sim - great fun but slightly terrifying especially in VR!

The Super Trophy Trucks (STT for short) are the exclusive class along with 12-dedicated ramp-filled track layouts in Adrenaline Pt2, expanding on the dirt content introduced in Pt1 It will sell for US$ 7.99 or the equivalent conversion to your local currency.

Adrenaline Pt2 is still part of the original Season Pass and the Premium Expansion Packs, so if you own either of these DLCs you will receive the Super Trophy Trucks on release at no additional charge.
This update also sees the results of big efforts into further bug fixes and optimization, which should grant most users a noticeable performance boost.

One of the optimization measures is that the physics engine now runs on four CPU threads by default instead of the previous default of two; this however might not be a net positive for users running substantially older systems, in which case they can revert to the old standard by running the command line -pthreads 2


The new Single Player options introduced in the V1.6 update - grid sizes of up to 48 cars for users with at least 12GB RAM, AI Wet Performance & Mistake Scalars - are now also supported in Single Player Championship Mode.


A final round of further tire physics developments to complement the V1.6 revisions have been performed for this update, with modern prototype & GT classes especially receiving some further tire modelling & default setup adjustments. The issue of slick tire compounds remaining a bit too effective on a wet track particularly while still hot and / or with low water saturation levels has also been corrected.

The GT3 classes have received further Balance of Performance revisions correcting some persisting advantages from the V10 powered cars.

The update also features another batch of AI developments, including improvements to AI calibration when running cold tires on a cold track.

Finally, V1.6.4 will bring adjustments and mitigating developments to reduce chances of issues and unfair penalties during rolling starts especially in a Multiplayer environment.

After this upcoming release. we will start a new development cycle for which Endurance Racing will once again be back as the primary focus; some new contenders are expected to join the GTP, GT3 and GT4 classes, including models from a premium manufacturer which will be making its debut in AMS2.

Along with the content other endurance--focused developments and Multiplayer improvements are expected to be concluded, but these are topics to cover in more detail in the next dev update.


If you still haven´t got AMS2 or you have items to add to your DLC collection, this is a great time to get in on the fun as several of them are featuring on the Steam Spring Sale with 70%. Recent DLCs like the Endurance Pack Pt2 and the IMSA Track Pack are on sale for the first time with 25% - check them all out here.

This covers some of our highlights for the upcoming V1.6.4 release - we hope you all enjoy it!
