1.3 AI issues

[hexagramme]

From the video description:

Assetto Corsa version 1.3 with Dreampack #1 and #2, fresh install, no 3rd party mods installed.

Opponent strength = 100%
Track surface = optimum

This is what I was able to observe/capture during 1 hour of gameplay with a handful of different car/track combinations.

00:03 – AI piling up before Eau Rouge for no apparent reason, AI not registering speed differences, AI not taking avoiding action, AI falling through the world.
00:22 – A lot of AI cars running on the grass instead of on the track, AI not registering walls/barriers and hitting them, AI not taking avoiding action to avoid hitting other slower cars, AI not able to brake after the car has broken down, AI falling through the world.
00:48 – AI rear ending other car, continues to race with the other car on top of it, the lifted AI is sent back to the pits and immediately races straight into the pit wall.
00:57 – Yellow AI car rear ends blue AI car, with no concern at all for the difference in speed. Yellow car races on as if nothing happened. Another AI behind doesn’t register the blue car is stationary and slams into it. The blue car’s physics go haywire, then it’s hit by another AI, and it almost falls through the world too.
01:30 – AI cars running off the track en masse, total disregard of the appropriate speed for that particular corner.
01:42 – Same thing, total disregard of appropriate speed.
01:49 – Same thing, only much worse, AI cars crashing even before the actual corner.
01:56 – AI car running off the track for no reason at all, then rejoins unsafely and gets hit by two AI cars. Again, they don’t even register the difference in speed and take close to no avoiding action.
02:06 – The typical pile-up before Eau Rouge. The AI is still unable to drive around stationary cars. It just sits and waits for the stationary cars to be moved off the track.
02:30 – Car clipping through the track surface and then sliding on its side in an unrealistic manner.
02:40 – AI car stopping on track for no reason at all. Then gets hit by another car which again takes no avoiding action or heed the yellow flags.
02:50 – Another nonsensical AI contact before Eau Rouge.
02:57 – This time the RUF AI stops on track for no reason at all. Other AI lacks logic to drive around the stationary car properly. Another big crash ensues.
03:08 – An AI car suddenly locks all four wheels and momentarily loses drive, goes off into the gravel, and rejoins the track in an unsafe manner. Another AI hits the first car, then another, and then another. Many AI cars drive off the track, plowing through the gravel.
03:39 – CPU 99% occupancy bug. Multiple AI cars swerving dangerously, which sends me into a spin and another AI then rams me into the barriers.
03:50 – Restart the race, AI still swerving and sends me into the barrier once more.
03:59 – AI cars running into each other, rejoining unsafely, overtaking on the grass and bumping into each other on straights.
04:28 – Me hanging back, observing some quite absurd AI behavior.
04:53 – AI smashing into the barrier for no reason, suspension physics going haywire, big crash.
05:08 – Another clip of the absurd AI behavior on Nordschleife
05:17 – Me hanging back, observing some more bizarre AI behavior. This time an AI keeps rear ending and pushing another AI car along the track, until one of them finally goes off into the barrier. The yellow AI car starts racing on the grass instead of on the track. After that, another AI plows into the yellow car.
06:16 – Multiple AI going off the track and ramming into each other.
06:24 – More absurd AI behavior, plowing into each other.
06:30 – AI running off the track and rejoining unsafely.
06:40 – More absurd AI ramming into each other.
06:46 – AI stopping on track before Eau Rouge, again.
07:03 – AI swerving, ramming each other and me, stopping on track, ramming each other some more, and lack the logic to drive around stopped cars on track.
07:32 – Most of the AI cars go off in the corner, some DNF’ing.
07:40 – AI cars slide all over the track, hitting the barriers and each other, causing a traffic jam. Yet again, the AI can’t figure out how to drive around stopped cars.
07:54 – Same story as above, insane driving causing DNF’s and traffic jams due to lack of logic.
08:07 – Another instance of the same problem, third time in one race.
08:17 – AI losing control under braking, then swerving wildly to defend, defending on the grass, ramming.
08:32 – AI making a mess ending up on top of each other.
08:44 – AI plowing into another AI, ramming it off the road.
08:51 – AI completely miscalculating the available grip, ramming the outside barrier, stopping on track.

I completely understand your viewpoint on SP vs MP. I was just pointing out your hypocritical double standards with regards to branding people. All I said was that MP was better than SP (my subjective opinion), and I get labeled as an "elitist" and that MP racers "act like little girls".

Lol and now I'm a "Multiplayer fanboy". Nice.

I am a premium member for about 2 months and I enjoy most of the RD AC online CLUB (friendly) races! I usually don't have much time for practice, I try just to be on time during the server's practice session, in order to be prepared, i.e. to spectate the fast guys, exchange setups and have a nice race! Obviously, I am not a fast driver, most of the times I finish the races in the middle position, but what really excites me is not to finish 1st or last, but the competition and the (clean) fights during the race, even if you are at the last positions... As far as people's behavior, I am very pleased with the kindness and understanding they have, whenever an incident occurs!

It is noticeable though, that I haven't seen any of you who criticize the MP at the RD club/friendly on line races, at least recently...

But that wasn't all you said.
What got you the elitist label (not from me by the way, I called you "shortsighted" which is different ) is the much echoed sentiment that devs should stop working on singleplayer completely just so they can focus solely on the part of the game you care about, at the exclusion of the other majority of players who you share the game with. The kind of does smack of elitism a little (though I'll still stick with "shortsighted" just for consistency's sake ).

Actually I would love one right about now. Got any milk to go with it Jebus?

Milk is for babies. And I hate babies.

Well - The main reason for me not liking MP is that I rarely find a car/track combo I like or know.
With SP I can pick and choose exactly what I want when I want.

Somehow some people find that really hard to understand

 

[Chris]

Yes but again, my opinion (even if others view it as short sighted, or elitist) was just that. My opinion.

I explained completely rationally and reasonably why I feel MP racing is better, and only one person has actually given me a reasonable response as to why they think Single player is better, Brandon. Most others have done nothing but hurl insults at me.

You don't see me calling Mikaela out as a "Singleplayer fanboy" and a "SP Elitist!" I give a different opinion and suddenly I'm vilified?

 

[poet]

Yes, it is your opinion, and of course you're welcome to it.
It's still an elitist opinion, cry all you like.

 

[Tobbe Bergman]

Sounds to me like you just want to be able to crash into people with no repercussions, yet when the AI crash into you the game is broken?

It doesn't get much dumber than that !

 

[poet]

Yes, because not once, ever, on all the sim forums I read and post on have I ever seen a SP-only player say that Devs should stop working on Multiplayer.
Seems to be purely an MP-only player obsession that one.

 

[Chris]

It doesn't get much dumber than that !

And that right there is exactly what I'm talking about. lol
Cheers fellas.

Eh, I wasn't saying SP is better, I was just saying there's a valid reason for it to exist and that it should not be excluded. But that gets to the crux of the problem, one style doesn't have to be better than the other and just because one person prefers one method doesn't mean they have to dislike the other method. The world seems to have become a place of "if you're not with me, you're against me" attitudes, and that's not a good way to be. This leads to a vicious circle of people feeling the need to criticize or bash anyone that has a different opinion than them. This accomplishes nothing positive.

For the record, I prefer MP racing, when my schedule allows it. But you won't see me calling AI racers uppity and deserving of a cookie for beating 1's and 0's, because how other people use their sim is none of my business and has no effect on my enjoyment of the sim. I say the more people sim racing, the better, whether they're racing real people or compubots I could care less.

No, and I'll admit (and apologise) that it wasn't the best terminology on my part. But nor will you see me referring to SP racers as "fanboys", "little girls", or "elitists" for simply expressing a different opinion. Because the moment those terms start getting thrown around, any chance of having a civilized discussion is lost.

I've already stated multiple times that I've absolutely zero qualms with how people want to play the game, because as you say, it's none of my business and I completely agree with you.
----------------------------------------------------------------------------------------------------------------------------

And with that, that's probably a good place to leave this as we've gotten someway off topic.

Back on topic: I know Hex has some what of a reputation, however those videos do appear to show some pretty glaring faults. Hopefully they can be addressed in time as I know that AI coding is arguably the most difficult thing to do.

Agreed. And that was really the only point I was ever trying to make. Cheers.

Problem with anything posted by Hex is trust - given the completely one-sided nature of his posts - I'm pretty sure anyone can make the AI look awful by setting grip to low, temps to low and setting a new, intentionally awful, racing line for the AI to follow - oh, and sticking them in a high powered monster with no downforce which would trouble most human drivers.

Not saying Hex does any of this, but there's too much anti-AC sentiment in every single post to make it sound feasible.

I've seen some poor AI behaviour, and some very good behaviour - Hex, have you enjoyed even a second of racing against AI?

 

[Peter Klawitter]

first thread/ topic says it all.
AI = crap! in all games across the platforms! devs/ publishers have neglected AI for 10 years or more!
(they should contact IBM and have them develop AI for sim games, like IBM Watson!)

PS: still love all sim racing games and race against AI no matter the problems and bugs! i enjoy every second of it! AC, F1 2015, pCARS, rF2...and all orthers!

 

[Peter Klawitter]

curious, question to all AC veterans, possible in AC to do race only AI's and spectate race(s)?

Yes, at least when I tested some AI behavior I usually put my car on pits and watch the AI racing each other. You still have your car on the grid. I place it at last, hit escape an send it to pits.

S

Come on Mikaela, it's because you are not very good at sim racing so you stick to Single player.

 

[paracletus]

All the drama aside, was riding onboard with AI at spa after the race, because they were no challenge in the Audi R8 set at 100% and wanted to see what the problem was.
Of course they slow down too much at Au Rouge, but worse than that they don't change down gear after braking & labour the engine in top gear - crawling along the kemmel.
Other than that, they are certainly quick on a few sections of the track.
It's not great yet by any means, but improving.
