Official General AI Comments & Discussion Topic

More new content with no urgency to fix game-breaking bugs is disappointing to see. I still can't complete a 2hr enduro at Daytona without the AI prototypes imploding at the slightest contact with each other. No reference to ghosting issues at major tracks causing AI to miss pit entry, run out of fuel, and start a chain of FCY's.

(Moved from Dev Blog to this topic)

 

I see you have only just now made a bug report about it , I’m not sure how you expect it to be featured as a fix in an unrelated Dev update , and it’s a very specific thing to expect in a blog .

Many many things are not mentioned in updates blogs that may see a much better experience for a user , there is just too many and would take hours to write , but overall Ai has had many improvements, but as mentioned in blog, it will take time to populate all classes.
FYI : Custom Ai files make report somewhat grey and probably won’t be considered valid .

 

That is my most recent bug report on the issue. I’ve posted 2 others in the past. I understand I shouldn’t have posted that on the Dev update thread though.

 

Ok, well it’s best to wait until after the update , try it out and see if it’s better or not , ( without custom Ai files) and if not post a follow up .
brief testing in Beta doesn’t seem too problematic, but I would need more time to kill to fully replicate several multiclass lapping scenarios.
The Bus stop is always something that can trip up some cars . ai will never be as risk averse as humans in ill-timed moments of traffic in certain places.

 

Circuit De Barcelona-Catalunya GP(no chicane) Might be nice and fun to race at. But there are a few AI tweaks that should be done:

AIs are only slightly a bit better through corner 12.
Another issue I also have found is, AIs are doing somewhat late dives on the last corner(14)
Pacewise, they feel a bit too fast. This is done with 105 difficulty.

 

This is just one short (!) demo of what happens when I try to race the AI in AMS 2. To sum it up it's hard to complete a whole race without any of these incidents. This was using the current version
AMS2 1.6.9.5 3233 AVX
Hockenheim short
Group C cars
No custom AI, all "stock"
AI at 95
Aggression: medium

Funny (sad?) too how the orange "Gold Seal" car in the first clip completely ignores what just happened and just runs into me even though anyone at this point would just brake refrain from accelerating and running into the collided car. But yes, I didn't really want to do any explaning...

 

I'm enjoying the AI making more setup differences and having a better refuelling strategies. It adds a nice layer of depth and can really shake things up sometimes. One thing I'm interested in is will we be seeing the AI using more appropriate dry tyres in the future?

It's a great experience running a short F1 race at Barcelona against AI but in longer races it's a bit easy when they're all solely on softs that burn up after a few laps when I decide to use mediums/hards and can just win by over a lap because the AI stop for new tyres 4 times while I only need to stop once or twice.

Just curious more than anything, very much enjoying the update!

 

In version 1.6.9.5 3233 AVX some issues are still there:

- AI still cut corners in order to avoid being overtaken by player. They then also have way too much grip when driving over grass/gravel.
- When driving in a pack of cars, AI in front tends to braketest player, whilst the ones from behind attack like crazy.
- When fighting the player, AI has magic brakes before corners. It can brake extremely late without damaging the tyres.

 

I think the AI cars' strategy is correct, but the AI cars don't experience a performance impact based on their tire choice.

I ran a 200 mile/50 lap race at Road America in the F-V8 Gen 1's last night. The AI cars pitted on laps 14 and 28, then ran to the end, implying a S/S/H strategy - very appropriate for the era. But the leading AI cars ran the same lap times in clean air for the entire race. So no difference in lap times for the different tire compounds.

 

Take a look at where your car is heading here. You have to aknowledge that there is a car beside you that wants to go around the corner too, you can't expect a full car width space next to the curb


The 2nd clip is hilarious, your audio spotter even warns left side and you just move the up to the left curb. Go defend the inner corner if you don't want a car accelerating faster than you going for the inner side. Yeah the clip 3 was of course a bit hard from the AI, but it looks like you were way too slow so tried to find a gap for his pace

 

Tested now 20 laps F-V8 Gen2 and AI cars have a drop in times after lap 14, AI 100.

For sure AI have a drop in times with tyres degradation. Maybe a lighter car can keep times at the end of race, but only devs can tell how all this are moddeled now.

 

AI atm is only running the Softest compound, so there are no S/S/H strategy unfortunately. Thats why their laptimes are so similar.

 

Yes, AI at least in Formula cars love soft tyres. Never saw AI pick medium or hard, in a range of 1 to 100 laps races.

This is because AI isn't tweaked yet to other compounds?

 

correct, for now they only use the softest compound on every class.

 

From what i have read over the years the "soft compound" we see on the AI is only visually represented, it is more like "medium", they have a universal tyre special for the AI.

------------------

Unfortunately the AI still does not know how to take an obvious overtake opportunity. Between lap 4 and lap 14 , P2 always yielded.

 

Yes, the tyre on the AI is modeled to be somewhat a middle ground, it mostly depends on the class, F1 cars very different from GT cars and so on, but in general the AI only runs the "one" tyre compound.

 

Do you recall the track temperature?
I've found they tend to struggle hard in hot conditions (Track temp 45°C+), they just seem to have a pace drop off after a few laps, and hit a cliff at about 10-ish laps at Barcelona. It's as if they're burning them up.

I mean, I don't know what it's like on the back end but as part of their setup strategy there could be a fairly simple compound choice scale with it being if track temp >= x +/- y (so they don't all pick the exact same strategy) then choose the hard the hard, else if it's <= x +/- y use soft, otherwise use medium. Add z value for race length, etc.
And the only difference really needs to be degredation rate and a slight change to overall grip. If only to have that visual representation of the F1 cars using the different compounds. It always takes me out of it when they're all just on the same tyre.

Edit - I mean "Fairly simple" as in the formula to choose a compound. I'm sure the implementation is anything but simple, especially with so many classes, etc. But it's just an idea, anyway.

 

I have fully enjoyed racing against the AIs on all the newly added tracks, sadly except for one track. And that sadly is the Indianapolis RC 2001. Here are the things I have found:

#1. Much like Virginia, at this track the AIs are feeling too fast in terms of pace for its difficulty, especially through sector 1
#2. The AIs are too good on the brakes on the first corner.
#3. Even with private qualifying, the AIs have really good straight-line-speed in the final sector!

*UPDATE*
These issues are more common with open wheelers. Have tried with F1 and Indycar. But with GT1 cars its different!

 

I really enjoy driving GT3 and GT4 at Imola, but the AI always causes accidents and ruins my fun. Please fix this issue as soon as possible. I remember reporting it many times—Imola is an important track too.
