UPDATE: v1.5 is now officially available!

Reiza Studios has always been open with letting the community know what is going on in the development of Automobilista 2. With the v1.5 update imminent, lead developer Renato Simioni shared a deep dive into physics development - and also confirmed the addition of improved wet weather track surface behavior.


RaceDepartment had already speculated in May that wet lines might be added to Automobilista 2 soon - the physics deep dive confirmed this, among other racing surface changes. Not only is the rubbered-in racing line going to be much more slippery in the rain come v1.5, but the addition of Rallycross and dirt surfaces will also change track evolution - laying down dirt onto tarmac surfaces will affect grip, but the parameters for this are still being refined, so the effect might not be perfect yet.

Behind the Physics Scenes​

Simioni also leans into the technical aspects of the physics and tire remodeling that mark a big step forward for v1.5. If you have ever wondered just how a studio transfers elements like suspension geometry, the chassis and body of a car, and tire deformation and interaction with the surface to a digital recreation of a racing car, this update is perfect for you.

Should the theoretical parts behind things like tire slip or the flex of a tire's carcass not be your cup of tea, the update still holds exciting news: For one, the second part of the June Dev Update - which was later renamed to July Dev Update - looks like it will be released after v1.5 has launched. Simioni mentioning the update being "just around the corner" turned into the update being available just hours later - for more info on the work that went into it, check out our recent in-depth interview with the Reiza founder!

You can find the full physics update in the Reiza forums. All cars that are already in AMS2 are going to profit from the v1.5 revisions to varying degrees. They will be joined by Rallycross cars and tracks, as well as the new Formula Dirt and Crosskart vehicles.

I dont care much for people liking one sim more than the other, to each their own. But when someone has such a blatantly wrong opinion I just cant contain myself, and your opinion that AC AI is better than AMS2 is just about the worst opinion I have read in this comments section, and that's saying something...
Could not agree more. To me, the AI is the worst aspect of AC. It was also, by far, the absolute worst aspect of R3E, when I played it. The AI cars behavior was almost psychotic at times.
 
It's so funny to read these comments. Some say the tires slide too much, others say there's too much grip, etc.

I always go back to the same question: how do they know? Have they driven these cars in real life?

If one doesn't like the way a sim is programmed, I perfectly understand. But to compare sims to the real life cars when in all probability nobody has driven these cars for real is always a bit useless, it seems.

Ai in AMS2 is not only bad and lacks awareness, it also looks awful and unimmersive with it's erratic movement, which is also something an ancient game like AC did better almost a decade ago.

I don't know why AMS2 seems to get so much trolling and useless opinions. If you don't like the sim, fine, keep playing what you like.

It’s because we cannot comprehend why some people so vocally call this their ‘go to sim’ and praise it so highly when the game tyre physic were and still are fundamentally wrong.
 
Well, i think i tried it enough :)

I like that some of the cars still have audible clipping and distortions in their soundsamples. Three years after release.

But this game is entertaining, have to give it that.

Especially enjoyed how AMS2 fans told everyone that it has the best physics ever and people just had no clue.

Only for Reiza themselves saying that they have been comptelety wrong the whole time. Can't make that up.
We have found Teddybearx's joke account. (not that his real account is any better)

tis a shame that by pointing out a porkchop is indeed acting like a porkchop it gives the porkchop the attention the porkchop is desperately craving.

To be fair nearly everybody sees their go-to-sim as the best and the only one which gets it right. I have used all the popular sims to more or less extent (+2000 hours in AC, +1000 in Iracing, +500 in Raceroom, AMS1+2, +100 in RF2, only 15 hours in ACC but that's because I don't care about GT cars, the sim quality is great) and can say with confidence that every single title has flaws and areas where they shine. That's just how it is. There's no perfect sim.

Thing is I don't visit every thread as soon as there are news about the title and leave a bucketload of s**t just in order to stir up…you know…s**t. ;) That's kindergarten. It's really like going to a good restaurant and telling all the guests that the food is shite (=arcade? :roflmao: ) and you know it better than the chef but unfortunately you're not in charge. You don't have a frigging clou, do you?

Has anyone got a video of the safety car? ^^

Does the safety car have a unique design, even in historic races?

On which races does the safety car not intervene?

Also not much feedback on the update and trucks sensations, any opinions?

Ah, I didn't know the head engineer of Pirelli is on Racedepartment too. It's always good to see that someone with so much field experience on the subject still can find the time to teach us peasants the working of a tire.

ah gotta love people who think subjective opinon is objective fact. AMS2 threads never fail to highlight that "type" of "person".

"My favourite game is Game A, Game B doesn't Feel like Game A so Game B SUUUUUUCKS."
 
I haven't been able to test many cars and tracks and I've been impressed by the classic GT and touring cars. They are much better than before and absolutely fun, the throttle control in corners is unprecedented (maybe too much, I don't know).

The GT1s and the Group C cars feel much more direct and "strong" but I haven't spent enough time on them to truly enjoy them, they felt really different, as if it was another sim. the Sigma P1 felt absolutely different too and felt closer to other sim titles. I need to find time to make further tests, it felt before overall but with different results. The 2023 Brazil Stock car felt good, not my favourite series (because I need practice) since AMS1, but, although specs are different, it drived similarly and in more enjoyable way for me.

One thing though, I've tested 2 karts, the rental and the 125cc ones, and I was quiet sceptical. The 125cc felt like an improved kart from AMS1, really good but not sensitive. Maybe it is this specific category, but the direction didn't feel as sensitive as in other sims, which maybe simulates other categories (Kartkraft, Karsim, Kart racing Pro), so I'm not sure about that. The rental kart felt atrocious : it had the sensitivity of fast karts from the other mentionned sims with no FFB around the center with a huge diameter, and it got strong without any progresion on the edges. This last car is a total disappointment, something seems broken.

Overall, the game is on the right direction and obviously some cars received more attention than others. We'll have to wait additionnal udpdates for some of them.

Karts are the only classes not to have the updated physics.

I believe they are pencilled in for the next update.

Only ever tried them once, many moons ago...decided not to go back...

I've been playing the RX alot, and I do think its significantly more fun than than the iRacing version, for a fraction of the cost. I did an open lobby last night and it was carnage, but in a good way, an absolute blast. Is it realistic? No idea, don't care. I had a lot of fun and was fully immersed. I'll never drive a real RX car so all I care about is the game fooling me into thinking I'm driving a real RX car, and AMS2 does a standout job of that. Same applies to the other cars in the sim. I'm not someone training for a real life race, I'm a gamer. This is a rock solid, super fun game that does most things right. Now sort out the multiplayer Reiza!

I had a race last night where I passed the leader and "he" stayed on my tail and passed me a few corners later and then we raced side by side, trading the lead and "he" ended up beating me by inches at the finish line. And while all of that happened the rest of the pack caught up and was on our tail, it was very immersive and exciting.

The two cannot be compared. Reiza has stated they had two tire models running at the same time, and car models would randomnly flip between the two models. This is because AMS2 is built on older codes from PC2. They fixed that problem, finally, now they only have one tire model running. However, that tire model has issues with slip angles as there is too much lateral sliding, which seems accurate to 60s bias ply models, but not modern tires.
That is not what they said. They said certain values to be input into the SETA model were taken from the pmotor code. The way this was done was incorrect and caused fluctuation of tires parameters in a way that would alter the parameters they were tuning into the SETA component in an unexpected and incorrect way. They never said there were two tire models and no flipping between anything, don't invent. There are just inputs pmotor had to provide to SETA model which is the tire model.
About slip angles it is the old quarrel in simracing between people saying that cars should have no grip after their tire's peak and those who say the opposite. None of the two sides actually having any objective back-up. Most of the real life drivers however say that real world tires are not as punishing for overdriving as the sims depict them. And this should already tell something.

Maybe because they don't think it's so fundamentally wrong? What makes some people think they can judge "fundamentally wrong" when they don't know much first hand about the subject and try and push it down to everyone else telling them what to like or consider realistic? That's really weird thinking.
