    Thanks for all your work, most of my reports have been fixed.


    "AI slow at start", they react and go too much slowly at start.

    Classes : DTM95 not fixed, still slow
    Ai difficulty : 95
    AI Number : 29
    Auto clutch : ON
    Tracks : all

    Mazda MX5/Porsche cup car 991+992 : fixed


    "AI prone to accident"
    Class : F1 90, maybe more F1
    Track : Watkins glen GP or with chicane
    % difficulty : 95
    number AI : 19 or +

    In this first turn, at start, with a pack, there is usually some AI touching the "violent" interior kerb, and it is an accident, when the are spread out, with train/queue, no issue.
    I have seen an issue when an AI tries to overtake in this corner, it will overtake in the interior of the turn, try to slighty cut, and will touch the kerb = accident. This kerb is the cause of accident.

    some AI take to much curb in turn 8 (without fighting with an other car) which unsettles the car and makes it spin. The orange car in front took less curb and was fine. Happens often in an 15 minute race. Formula 4 seems fine, no issues

    Super Touring at 100% at Silverstone Circuit Classic - Luffield and Copse discrepancies from the Grand Prix layout and the International layout.

    On the international layout for me personally the AI are awesome and I honestly can’t fault them. I’ve done several races between ten and twenty laps and I score them 10 out of 10. Only nitpick is they could cover the inside line of the hairpin when I’m attacking them, but other than I can’t fault them.

    I’ve done several races on the Grand Prix layout again between ten and twenty laps and used all the cars available and always same settings of afternoon and no clouds.

    On the Grand Prix layout they have superior speed and traction through Luffield and they pull away from me every lap exiting Luffield, through Woodcote and down the start finish straight. They can even get passed me going round me on the outside with a tyre or two in the dirt at Luffield and still pull away from me, it’s almost like they get a boost going round that corner but only on the GP layout.

    On the International layout they have equal speed and traction to me and on the odd occasion I get to Woodcote a head of them, I can inch a head down the start finish straight preparing for Copse and it’s completely fair and fun and causes me zero frustration.

    This boost the AI get at Luffield GP layout causes further complications at Copse where the AI are following me and gaining on me through Woodcote and the start finish straight, they can close the gap by around 0.3 to 0.5 seconds and if they are within half a second of me they keep sticking their nose on me going into Copse if they are close enough or if not close enough they take a tighter line into Copse instead of following me on the racing line. This hasn’t caused any contact or wrecks with me, but because they are needlessly taking a tighter line it’s compromising their exit speed and by the time I reach Maggotts I’m 0.3 seconds a head of them which ruins the racing each lap because they should still be on my bumper.

    I’ve tried to recreate this at the international layout many times, but they never get boosts out of Luffield and they always take the correct line through Copse when within half a second of me and they stay stuck to my bumper going into Maggotts and they are perfectly behaved at International and again I can’t fault them. But GP layout they make me grind my teeth every lap from Luffield to Maggotts.

    One last thing that I’ve never noticed before, the AI’s speed is not affected if they go two or four tyres into the grass and dirt. I kept one AI and all four of his tyres in the dirt the whole way down the Hangar Straight and three quarters of the way down he inched his whole car ahead of me whilst driving all four tyres in the dirt and got to Stowe before I did. If I go in the dirt, quite rightly my car slows down a lot and it’s bouncing all over the place and hard to control. AI don’t have any adverse effects driving in the dirt and can continue on as if they were on the grey stuff.

    "AI brake too much and slow"
    Class : any car
    Track : Brands Hatch GP
    % difficulty : 108
    number AI : 29
    [​IMG]

    I report again this this as it's still present, and it's not about lap time or sector, I use on purpose a faster AI than me, 108, they are faster in every corner than me, but at those 2 corners I can close the gap cause they are too much slow and brake too much

    "AI generaly slow"
    Class : Super touring
    Track : Brands Hatch GP (maybe more)
    % difficulty : 108
    number AI : 29

    Usually I use 98% difficulty

    EDIT : finally not so much, I have found the good value at 102, on the tracks where I'm good

    Edit 2 : finally 98 is my skill, so no issue

    Class: DTM 2016
    Track: Moscow Full
    AI: Adaptive AI, normally around 105-110%, Full DTM 16 grid
    Start Position: Tried it in P3, P8 and P15

    I tried it five times, results were always the same. The start is an ai wreckage after turn 1, a lot of cars are losing their rears and causing a mess. If you make it through that carnage the lap itself is fun to drive and the ai lines are good too..until the last corner, many cars are overshooting the corner and are overcorrecting back to track (which sadly occured at many tracks I raced the last days) which results in brutal rejoins wrecking those cars that survived the T1 incident.

    AI seems to have an advantage in speed and acceleration at long straights. AI is faster than me at long straights. Even if i am into the slipstream they pull away from me or easily overtake me. In turns they are slow so i could easily overtake them. I think this is car related and not track related as other cars are fine. Screenshot 2024-12-15 193049.png

    I have the feeling the AIs brake too much early and strong in many many corners, obvious with FRX22, but noticeable in all the others cars, Imola, Brands Hatch, Nordschleife...in the others game, in Brands Hatch, Imola or Nordschleife, no issue, I dont bump the AI from behind. It's not about lap times, to test it, I put stronger AI than me, and I can't follow them, but they brake too much early in many corners, I have already reported this in the september AI thread.

    AI off track with insane speed and grip
    screen shots of results: see below

    mention the ai: adaptive - championship

    explain the issue ; Volvo (ai) car went wide, got off the track and was as speedy as on the tarmac. No issues at all to get back to track and kept its position. Like there is no gras, gravel etc. for the car.

    how many: 1 example, see pic (but I noticed this in other races as well. Always by Super Touring Cars.)

    starting position: last

    Tried Group 5 at the Norisring, difficulty 90. Again, at this relatively low difficulty level, the AI were just so damn fast, it was unbelievable. I drove the Fabcar 935, which has chronic understeer, severe locking of the brakes, and setup the car to extremes to try and negate this, but it’s a lost cause, and the tyres stay cold for a long time. I’ve noticed with all classic content, i.e., cars without TC/ABS that the AI do not have these issues, but zip by with super fast lap times, without locking up, understeering or clearly don’t have cold tyres, as they are super quick from the get go. I’m competitive with most other cars, but with classic content, it appears to me that issues I mentioned, which are right, understeer and brakes locking up have been adapted for the user, but are clearly not applied to the AI. Any thoughts on this? I noted the time of the fastest car in quali’ with the screen shot, 51.379 after 4 laps, again at difficulty 90. Tried for another 30 mins and just gave up, it was hopeless.Tried with ABS this time, and the AI are still outbraking me, but time at difficulty 90 is a little better, with 25kg ballast. The state of classic content against the AI is a real disappointment, and almost pointless.

    AI brakes without need instead of going full throttle at uphill to start finish. There seem to be two racing lines. The inner one looks good, the outer one has the braking

    yellow flag nearly every lap in T1/T2 = chicane after start/finish. Happens when in single row. Seems the car oversteers after turn 1 and when countersteering it spins or comes nearly to a standstill

    Please please read the first post in this thread
    It is really important for us to get the lap times ; both yourself and the Ai as this can make a huge difference in the way we treat any ai issues

    Thanks

    Quick question, if I’m using adaptive ai, how do I find out what strength the ai was running at?

    lap times added but in this case its hard to do a clean lap as you have to slow down nearly every lap because of a spinning car in front of you
