Just a week after the latest update, Automobilista 2 v1.5.5.4 has dropped. The new patch includes changes to AI behavior in battles for position, a fix for wet tire wear and more LED flag lights.

Even after the big Le Mans update on New Year’s Eve, Reiza Studios are hard at work. Just a week after the previous version, Automobilista 2 has been updated to v1.5.5.4, featuring numerous tweaks and fixes. This includes a bug that saw wet tires wear out at an unreasonably quick rate – now, they should perform as expected.

The new update also continues Reiza’s quest to become the go-to singleplayer sim. Multiple AI parameters have been adjusted, meaning on-track battles with them should be much more realistic. While they will not make unreasonable moves and go off track as much anymore, they should also attack and defend in a more believable way. Do not expect them to jump out of the way anymore just because you are close!

Meanwhile, the recently-introduced LED flag panels are now in working order on all grade 1 tracks in the sim. They also support local yellows and are permanently green when there are no incidents to signal. The panels also work on oval tracks as of Automobilista 2 v1.5.5.4.

Reiza, as a Brazilian studio, also included a nice tribute to one of its home country’s famous racers. Gil de Ferran unexpectedly passed away on December 29, 2023. The 2003 Indianapolis 500 winner is honored in Automobilista 2 v1.5.5.4 via a tribute livery on one of the F-USA Gen 3 cars – resembling his title-winning car of the 2000 CART season.

Yeah or mid-race saves... I cannot understand how one is supposed to have an offline experience if not able to stop at any time. How are you suppose to take on endurance ?
Click to expand...
Yes i already decribed it in an another threadt - there are also some Reiza created championships, but most are not possible to play, because of the missing possibility to save like you said.
Another half-soution would be the possibility for the user to modify the Reiza championship slots. There are plenty of them.

Assetto Corsa is the best single player SIM because it actually feels similar to real driving, unlike Automobilista 2 which feels like constant WIP. i keep AMS2 installed though, because i hope one day it will improve to atleast AC level driving realism, and hopefully modders can do great things to AMS2 like they have with AC, but i see the modders are more interested in working on AC as it just works.

Well, IMO we´re still far behind in tech to feel a racing SIM similar to real driving. Not even with VR. And talking about AC it needs a lot of tweaks to the AI and some tracks to be really competitive vs a human player.

I can arrange myself to any AI in games i play. These are AC, AMS2, R3E besides Rallying . All feels quite different, but all are very playable if set up correct. Non is really bad and no one very good for me. But like said, i have fun with all 3 games.

AC is still No. 1 just because of the endless variety amd content, while AMS2 immerse me the most while driving. And if i must choose the best vs AI experience. Well i would name Raceroom as No. 1

Ai movements have improved a bit but the faster classes are still struggling to pass the slower cars entering and exiting corners, once they pull out to pass they seem to hesitate and drive beside the slow car matching its speed for a few seconds and then accelerates.

It is because most of AI file are set with high blue flag parameter... just set:

<blue_flag_conceding>0.50</blue_flag_conceding>

The AI have gotten worse since the version released in the big driveability update with the Hi Tech cars, certainly for fans of historical F1. That was when the AI were finally interesting to race, partly as they were more consistent and respectful, but also that they had some unpredictability lending them some much needed character.

With the Le Mans update they "Disabled AI half-spin mistakes on corner exit" which already half killed the fun of single seaters (one suspects because the GT3 Endurance crowd disliked the effect and in fairness it isn't as suited to a GT3 as a 80's/90's F1)

With the latest update it seems to have gotten worse again. F1 cars back to clumps and chains of bumper to bumper, rarely if ever managing an overtake, woefully easy to slip down the inside on numerous corners on numerous tracks.

It gone from been great fun with an unpredictable, evolving racetrack back to a disheartening race on rails with placid AI within a couple of updates.

An endurance race, it's nature about caution and consistency is not the same as 90 min circuit race, but in fine tuning the AI the former seems to be dictating the direction of travel.

Hoping Reiza find an answer because it will be the F1 nuts playing this game long after the GT3 crowd have moved onto something else new and shiny.

I agree on the AI losing their ability to overtake and the pack racing on single seaters (haven't really driven a lot of tin tops to see if they have the same issues). However they still do mistakes, they just changed the half spin tank slappers on corner exit, to mistakes on corner entry. I have seen some pretty spectacular crashes from the AI losing it under braking, they look much more natural than before.

But I do agree that the AI has regressed in their overtaking ability, still I am hopeful they can improve it.

What is the name/location of the file I am looking for to change those parameters?

Is there a general AI file or is this tweak for custom AI files?

I've never played with any of the AI files before.

Cheers

We are simracers. We are searching for the most realistic and most authentic simulation possible. And this begins with accurate cars.

For the sake of god tell me who needs 300 or 400 cars. Who can drive them all. And most importantly who can make them all with as realistic physics as possible.

So titles like assetto corsa and automobilista 2 are frightening me to say the least.

And to be honest I still prefer automobilista one.

Good thing is we all have the freedom to choose. And in case of AC and AMS2 you might miss some really good cars. I also don't use all the cars in AMS2 but it's nice to have choices and the ones I have driven so far felt believable and were fun to drive. Fun. A word not every simracer understands.

Well, my Moza wheel arrived, fired up the mighty AMS2 and ran a 2 hour endurance race at Bathurst. The A.I were aggressive, fought each other and took advantage when I missed the apex. The car (GT3 Gen2 McLaren) fell planted and predictable.

There were the occasional twitches from A.I to get out of my way when in real life they would have held their ground but that happened probably twice. A really fun experience and for me, offline this is the number one sim by a country mile. 2024 is going to be a big year and with Le Mans, AMS2 is now my go to, the cars feel so good.

The updates have been solid, I've been running @EverlastingApex s Procedural Career mod and MarcoVSantos For the Win mod and been really enjoying the varied car/track combos.
Looking forward to Reiza hopefully implementing a career mode which at the very least matches project cars 1 career mode.
It's a shame it was delayed 4 years and now forecast for 2025. Keep up the great work Reiza and modding community

The AI in AC is horrid though. It has rare moments of the right car, the right track, the proper AI line setup resulting in a somewhat competitive race, but it's about the worst racing AI in the market currently. I love AC for what it is, but it's not a great SP racing experience.

I would counter the whole "...actually feels like real driving" but that never results in worthwhile discussion. Needless to say, based on my own track experience, AC has plenty that feels "off," just like most every sim available to us at the moment. It's just a matter of what "off" portions of any given sim the individual deems most impactful/detrimental.
