Official General AI Comments & Discussion Topic

Track and layout used: Pocono Oval
Car: Stock USA Gen 1 (applies to Stock USA Gen 2 as well, have finished a full race weekend with both under these same conditions, have not tested with Gen 3)
Ai settings: 112%, medium aggression
Report: AI is slower in turn 3 compared to expected times based off their turn 1 and 2 performance and player’s times. Also have a tendency to hit the wall out of turn 2 more often than one would expect and dip below the apron fairly regularly on the same turn 2.

Also, ai for ovals in general seems to be calibrated to a slower pace/difficulty compared to the normal road courses AI. I usually need to raise the ai difficulty level from the normal range I play with of ~102-108 to ~110-116 for a similar level of competition.

edit: after testing more oval racing, on top of the multiple races I’ve done prior to this post since the release of the stock cars. It seems that on ovals with more braking involved like Pocono, or even Indy and Gateway, the ai is slower than usual, but at more high speed ovals such as Daytona and Fontana they perform at a level much faster than expected for their difficulty level. Understandable for the second part considering it’s based on cornering difficulty and there isn’t really as much there to adjust for but oval ai when the corners are a bit trickier to navigate does seem to be performing at a lower than expected per difficulty level chosen in my opinion/experience.

 

Track and layout used: Laguna Seca
Car: Lambo diablo V12
Ai settings: 120%, medium aggression, default mistakes
Report: AI always does this side to side move when they're in a pack, it looks like they intend to attack the car ahead even if they're nowhere near close to make the move, and they don't care if you're along side or not. Video to show what I mean.

 

Track and layout used: Nurburgring GP 2025
Car: German Group A
Ai settings: 105%, medium aggression
Report: AI seemed to be taking too much of the sausage curbs at the last chicane leaving them prone to flipping themselves over and/or on their side (no contact from other cars, just over aggressive on curb) (possible/likely that it only happens when there’s a few/at least more than one ai grouped up on the straight before going into corner?), happened on the first curb on the first lap by a Mercedes and on the second curb by a BMW on the third lap (second actual racing lap since first incident triggered fcy), both directly in front of me by a few cars so was able to clearly see it happen during the race live and viewed in replay to confirm. Also, happened one more time during the same 25 minute race.

 

Track and layout used: Mosport
Car: GT3 Gen2
AI settings: 110%, high aggression
Report: On T8 (the right turn after the straigth) the AI is sometimes going too far over the inside curb, making them drive on two wheels for a moment.

 

Track- Nurburgring Veedol
Car- Group C (I was in a 962c, the AI was in a C9)
AI- 100% Medium
Report- At Time 44:10 mins, Lap 24 I'm at T1, the C9 AI overtakes me. At track exit he warps through me. It should have been contact because the AI was not exiting the pits.

The game version is not the most recent, I rolled back to 1.6.8 through Steam

 

In my last two f1 seasons (classic gen 3 and gen 4) using all locations available in game, I used 107 AI having a decently balanced experience (sometimes they are faster, sometimes slower, but the variance is reasonable).

Except Suzuka. Suzuka is a clear exception, even at 115 I won with little effort (I usually do some points (top6) and had 2 or 3 podiums in the season). They are slow in all three sectors.

 

Track and layout used: Daytona Sports Car Course
Session: Race 40 min wet (soaked track)
Car: Lamborghini Diablo Super Trofeo
Ai settings: strength 112, 1x wet scalar, medium aggression, 1x mistakes
Report 1: The AI breaks very late into the busstop.
Report 2: The AI is slow through the busstop. They seem rather slow through any corner, specifically at the apex.
Report 3: The AI is quite slow compared to the dry. I normally run at AI strength 110, but at 112 in the wet I just drove away from them, being up to 1 sec faster per lap (2.01 for me vs 2.03 fastest for the fastest AI.)

 

Not trying now to pressurize you guys at Reiza. While I can sense that we could get some news soon, I so am praying that the next update will fix the previously mentioned issues with Road America. Been trying to enjoy the track but its hammered down with these issues.
The most obvious ones like: Late braking into turn one after the opening lap, AIs leaning on the inside throughout the whole "Road America Straight" and them being slightly up through corner "Kink".
But I have found some more concerns: The AIs tend to be a bit alien-like in the last corner and when I manage to overtake the leading AI driver, they will then start switching up their pace which doesn't happen if I am behind them.
Here is an example happning using LMDH with skill level 107:

The leading AI might make around 1:51 but when I pass it, the AI then makes 1:49s!

 

Track and layout used: Imola 1972
Car: Formula Vintage G2
Ai settings: 120%, medium aggression, default mistakes
Report: Tamburello the AI has a tendency to go wide while defending but then cuts abruptly into the path of other drivers, frequently causing collisions.
Variante alta you can go flat out in the L49C, I understand some cars may not be able, but every AI seems to slow down way too much in that particular section loosing easily 3 tenths vs me.

 

Track and layout used: Silverstone
Session: Race 20min Dry
Car: Porsche 992 cup (mod) & Ligier JS-P4
Ai settings: strength 107, 1x wet scalar, medium aggression, 2x mistakes
Report : The AI is overall very slow in the 2nd sector starting from abbey corner until Brooklands.
they do no use the curb on entry in abbey corner, and immediately hug the left side and overslow instead of using the whole width of the track, resulting in an easy cheese. At loop/ aintree they also do not carry enough speed into the turn and follow too tight of a line instead of using exit curb

 

All Watkins Glen layouts are inconsistant with the AIs. Here are the issues I found regarding each layout. And bare in mind that, if one issue isn't mentioned in a different layout then I can confirm the issue doesn't exist on that version.

Short(Inner Loop)
This one is more severe compared to the rest! AIs can easily fly through turn 2,3 and 4 without lifting even with cars that impossible to go flat-out at this section. Can easily lose 0,4 seconds! Have tried it with all Nascar types and the Diablo ST. The other issues I found at this track were, AI do late braking and diving at the "Inner Loop" and the final corner.

Short
A very minor issue! AIs are slightly better on the exit of "Outer Loop"

GP(Inner Loop)
AIs are so slow through the "Inner Loop. They also do late braking and diving at the final corner!

GP
This happens more with GT and LMP cars. AIs make late dives on the "Outer Loop"

 

I just hope someone can come up with a slightly more intelligent AI for multiclass races. Maybe teach them not to intentionally rearend slower cars and brake check faster cars on turn exits, especially on the first lap.

 

AI is a complicated thing. I'd like to see a more realistic and intelligent AI, attacking, but mainly defending well. Honestly, I don't want an AI with the same physics as the player (imagine the hardware needed to run it well!). My simple PC can't handle it, so I understand the limitations they face. It must be very difficult for the developers. And to be quite honest, of all the simulators I use, the AI in AMS2 is the best. The only detail that always weighs on me is the variation in skill between tracks (I even noticed that the more challenging the track, the slower they are). The funny thing is that AMS1 is the opposite. For example, two different tracks, Buenos Aires #8 and Curvelo, in AMS1 I'm better in Buenos Aires but lose badly in Curvelo, AI at 105%. In AMS2 Curvelo, I drove with an AI of 117 and won easily, while in Buenos Aires, at 110%, it was difficult to keep up using Stock Car Brasil 2017 in AMS1 and 2019 in AMS2. Well, to sum it all up, what I want to say is that they are on the right track.

 

I have found for quite some time an issue with the AI just not seeing the player and rear-ending them at high speed. I am tinkering with vr setup atm and parked up along the long downhill straight towards the kink at historic Spa, off the racing line and while not paying attention to what is going on in the game get absolutely smashed by another car followed by a huge pile-up, all clearly visible from a long distance.

 

That, I can understand a little more than being rearended and pitted 10 feet past the apex of a hard right turn by a car that that forced me to lift at the exact same place in the previous lap when I was right behind it instead.. tests the limit of credulity in a way that makes you think "WTF was THAT?"

 

Track: Sebring
Car/Car Class: Porsche 911 GT3 R/GT3 Gen 1
AI Difficulty: 103 (not really relevant)
AI Aggression: Medium (also tested max aggression with similar results)
AI Mistakes: 1x
Issue Described: The Porsche 911 GT3 R remains one of the few cars that the AI still spins out at T1 frequently at Sebring when it's racing with other cars. It is prone to losing the back end mid corner and then either hit a car on the left side of it or if no car is there smashing into the wall. It then has trouble if it's facing the wrong direction of getting going again as it spends an excessive amount of time trying to turn around. This behavior causes excessive FCY, leads to all the Porsches crashing out and being heavily damaged in races, and in the AI hands makes them completely uncompetitive to the rest of the field.

 

Now with you developers mentioning that V 1.7 being set to become a "massive" update, I so hope you read what we are seeing AIs being a problem with. I still have fingers crossed you will fix all issues!

But here is another alarming issue:
Spa 2022 remains in very very good condition with the AIs and can't complain about it. Sadly, Spa 2020 is broken!
The issues are, AI being somewhat slow in S2 but the worst part is that they literally warp and cheat through the final chicane(Bus Stop)

Skill level 107!

 

Thank you very much for the great work. I love the game! But I have a problem: Before patch 1.6.9.5, I drove several hundred laps with formula usa on Long Beach. Since the new update, the AI has become extremely aggressive and keeps crashing into me, forcing me off the track, or getting stuck in my car. It no longer recognizes the distance to my vehicle properly. It’s frustrating and impossible to complete a race. I reduced AI aggression from max to medium and AI strength from 100% to 90%, but the problem remains.

 

1.6.9.5, AI are still ramming into non-host players in multiplayer. It's almost like they're not accounting for ping, otherwise this game would be perfect for MP with AI racing.
