    That’s honestly awesome of Raceroom! That and WTCR cornering tune too!
    That’s put a huge smile on my face!

    Ningbo full no chicane ai tested at 100% 106% and 110% 10 laps standing start 19 ai cars no quali I start 12th out of 20 default set up WTCR 2019 in the Golf as always haha.
    Massive improvement I didn’t hear the words white flag once during each race at each AI level.
    They are incredibly slow through T6, they look scared and confused by it. At 110% they are losing on average about 0.6 of a second through there to me, but then will claim around 0.4 of it back by getting crazy high traction and grip through the following series of right hand corners and the tiny straight to the hairpin. The final three corners and the start finish straight they are absolutely murdering me.
    At 106% they are of course slower at T6 and can lose anywhere upwards of 1.0 second to me at T6 and the with their extra traction and grip boost they claw back about 0.3 to 0.4 seconds of it through the following series of right handers and the short straight to the hairpin. The final three corners and the start finish straight they are well behaved and have normal speed.
    I’ll try 108% tomorrow evening.
    Overall what a huge improvement, thank you so much! They only need a tiny tweak in T6 and a bit of encouragement not to be so scared of it and they are perfect I’d say!
    Really appreciate you guys taking on our feedback and then fixing it, that’s really cool of all of you and makes us want to test more to help with the AI!

    Car: DTM 1995 Pack
    Track: Hockenheimring Classic
    Start: Rolling Start. P 15, Q 15, R 20min.
    A.I Skill: 100%
    A.I Aggression: 50%
    Lap Time: I usually do around 2:12.xxx, and I usually manage to qualify at P9 - P11
    Grid count: 31 A.I cars, but it also happened with a 20 A.I cars grid.
    Corner: Senna T10

    The problem is: very often, during the race on the exit of the third chicane, you can see a random car, most times it's the Benz, going wide in the left side of the track in the sand, causing a pile up and incidents with the other A.I, trying to re-join the track. It does not happen every lap and when they drive in a row, but most often when they fight for a position. Usually it happens 3 - 4 times in each 20min race I do.

    Good friday!

    ai 102 %
    40 cars, GT3
    track /layout: Paul Ricard 1A-V2 (with slow first chicane and No chicane on back straight, typical GT3 layout)
    standing/rolling start: rolling
    start position: last
    Race duration laps: 6

    On the first S chicane some random Ai cars spinning and crasing. As well as turn 3 (long right hand curve before back straight). Ai rejoin desperately, causing even more hits with AI, and traffic jam appears. So in just few laps you already 20+ cars ahead.

    The fast right curve after long back straight: Ai going as fast as they have a ground effect on their cars, completely unnatural. Its impossible to go this fast, at least you can never see it in real onboards.

    Rest part of the track is OK. But this time it's not really playable with Ai

    turn 1 clusterfuck. Some cars hit the high curb in turn 1 to much/to hard which unsettles them and make them spin because of driving on two wheels, causing a pile-up. Happens every race so far. Hitting those high curbs seems not to be a good idea.

    As an old RF2 AIW modder i would try to adjust some corridors where high curbs are

    Not that I did an extensive test, but something is broken since the last update, apparently.

    ai % - 103%
    # cars 16 GT3 (911 R992) +22 BMW M2 CS
    track /layout - Dubai GP
    standing/rolling start - Rolling
    start position - 16 (last GT3)
    laptimes/screenshot of result - n/a

    They were doing good on practice and qualifying as well, but race turned out to be a GT3 wreck fest on corner 10 (hairpin after long stright). Thing is I don't believe there's a problem on that particular corner but the ai, that seems to be lacking the awareness she previously had.

    In my experience the ai made contact on very rare occasions, and most of them it was I to blame. They were able to locate me when I attempted to overtake, and left space to engage in a side by side action. They were also successful in attacking my position without banging my car.

    Now, both in aforementioned Dubai race and a practice at Watkins GP Inner Loop with 30 Mazda MX5 @103%, they often rear-end me on corners and even some straights, and always close on me when I manage to get side by side on a corner, forcing me to off track if I don't want to suffer an accident.

    Sorry I can't provide more and better evidence, it's that sometimes it feels like they can't see me :grin:

    Edit: all gt3 were 911 GT3R 992

    WTCR 2019 at Portimao Chicane layout 100% AI and default set up but added one click extra rear wing, 19 AI cars I start 12th standing start etc.
    WOW what a massive change and a huge improvement! It’s like I’m playing a completely different game compared to last week and the last handful of months.
    That WTCR cornering speed adjustment in latest update is very noticeable thank you.
    I need to up AI level and I’ll test again either tonight or tomorrow but at 100% I’d say they are braking at the correct points in the heavy braking zones of T1 and the hairpin.
    The final two corners leading on to the start finish straight are completely fair now, they aren’t defying physics anymore, they aren’t going off track and cheating for more speed and I’m actually quicker than them through the final two corners and can play and mess with them.
    My only criticism is that they get a speed boost on long straights but it’s massively decreased compared to what it was.
    Coming out of those last two corners I can open a gap, which is awesome, but once we start going up the little slope the delta will decrease and you can see them coming back at you. Fair enough they could be drafting and seems fair BUT
    If I mess and play with them and we go into the final corner either equal or me slightly ahead and I hinder their line and I can see the AI ease up to let me stay ahead and they lose speed and momentum and I give them the narrower line, by the time we start going up the little slope on the start finish straight you will see the delta start to drop and they claw back around two tenths back going into T1 because they get a visible second wave speed boost down the start finish straight. Where really given they let up off the gas and I maintained the better line speed and momentum my lead should be increasing by quite a bit.
    It’s subtle but no matter what the circumstance of the AI and their momentum compared to me whether good or bad you can see that delta drop, where in some cases I should be increasing my lead or drafting them and getting closer to them.
    It’s the same when I’m following them out of the final corner you can see me physically close the gap and have the greater speed and momentum because I’m better than them coming out of the final corner and I can catch up to their rear bumper or in some cases almost side by side with them and then they will start inching a head again from the boost being activated.
    I’ll try other circuits with long straights and see how they play.
    Honestly though, the WTCR updated AI cornering speeds has made racing WTCR 2019 AI so much fun again, thank you so much!

    To add to this, because I thought it was related to the car class, but it looks like it's not. I also did races with:
    DTM 1992
    TCR Cup
    WTCR 2019
    Audi TT Cup 2016
    BMW 325i Cup
    GT3

    I tried with A.I skill 100% / Aggression 50% also Adaptive A.I. . Every class, every race same error at the same turn.

    Not so regularly the A.I have problems in first chicane, but it's at acceptable rate.

    Second chicane 99% of the time is OK.

    AI - 100%
    Car - F1-22 (default set-up)
    Track - Silverstone Grand Prix
    Practise Session

    It was only a quick practise session but the AI seem too slow through Sector 2. In particularly, I think they're too tentative through the twisty section from Maggots to Becketts.

    Silverstone Grand Prix ai tested at 100% 10 laps standing start 19 ai cars no quali I start 12th out of 20 default set up WTCR 2019 in the Golf. I will need to increase AI percentage as I’m quicker in the corners through out the circuit, not a game issue at all, they brake in all the right places for 100% and nothing looks or feels out of place for them braking or cornering, thank you!
    Firstly thank you for sorting the AI out through out the whole of Luffield, that used to drive me bonkers how unfair and quick they were through there and now I’m quicker than them at 100% level.
    The WTCR cars get the second wave speed boosts at Silverstone too. No matter if I hinder them to get them to ease up, if we come out of a corner side by side I can look to my left or right and you can see their car activate and creep ahead. You can also see it when they are just in front of you ( bumper to bumper ) I never get any draft advantage of any kind. It’s the same when they are half a second behind you coming out of a corner into a long straight they creep back or creep ahead with a secondary boost and it’s on average around 0.2 seconds.
    I’m killing them going from Abbey into the loop, but out of the loop, into aintree and down the wellington straight they are destroying me and getting crazy boosts and I can never draft them, keep up with them or pull away from them. Again it’s massively decreased since pre three days ago update, but it’s really noticeable in this part of the track.
    Coming out of Luffield I’m miles better than AI and have better traction and momentum and you’ll see your delta increase your lead, but going down to copse they take some of it back, same again at copse and then again coming out of Chapel onto the Hangar straight.
    My lap time is 0.750 faster than the second place AI who had the second fastest lap but in sector 1 he beat me by 0.3 seconds and all other AI are very comparable, but I’m destroying them from Abbey to the Loop entrance ( I would need to up the AI percentage for it to be fair ) but coming out of the loop down to Brooklands they are getting straight line boosts regardless of easing off and momentum carried through Aintree.
    A million times better than it was, it’s now fun to race, but it’s soul destroying watching the AI get speed boosts on long straights. I did try different levels of rear wing and it’s the same result each time. If you can pull the same magic that you did on their braking and cornering for their long straight speed, I’ll be over the moon and these AI will be perfect as it’s the only negative / critique I can find on them.
    Right time for an afternoon nap watching the F1 haha

    1. AI spins after hitting the higher part of the curb in turn 1. Driving on the lower part of the curb seems ok. Had yellow flags in every lap.
    2. Clusterfuck in turn 1 every race in lap 1

    A bit of a follow-up on Watkins Curse(Glen):
    So after the recent patch on the Watkins Glen AI pace tune, I gave the track another shot to see what was done. The layout GP with chicane is now at it's very best. I really enjoy the track now fully and cant complain about it that much now that fewer things bother me with that, but sadly same can't be said for two other layouts I have given a try:

    Problematic layout #1
    Layout:GP without chicane
    Car: GTR3
    AI difficulty:98
    Starting position: 10th

    Somehow, it feels like the AIs are just slightly faster out of "chute" which I do not feel with the "chicane" version.
    The rubberbanding is still not cleared on this version! And the AIs still make insane lap times!
    Also is it just me, or are the AIs way too fast on the straight? When I am in front, they literally snipe me with higher straight-line-speed but when I try slipstreaming the AI, I can only catch them very very slightly compared to them.

    Problematic layout #2
    Layout:Short wth inner loop
    Car, AI skill difficulty is the same as before
    Starting position this time:2nd

    Still the same rubberbanding here as well as the insane straight-line-speed just as mentioned before but it also extends through the straight between "the loop" and the penultimate corner.
    When you take the lead, the AIs tend to have better handling in the last two corners.

    PS: I know dear developers I have moaned a whole lot about this track and its issues but dont be too surprised why I am not mentioning any other when they are a charm. Which also include Brno, Nordschleife, Road America and Most

    there is no rubber banding in the sense that the ai have a minimum and a maximum lap time and in all my efforts they have never been faster than the minimum lap time , so sometimes they will run between the two or at one extreme or the other , no ai driver is given more or less , so any of the cars can be faster or slower

    Still not fun that it only happens on this track all the time..Pay also attention to that Mercedes that finished P2. That AI was seconds away from me but then had massive pace advantage straight out of the blue..

    Exact same car, race and AI as above replied to message, AI set up at 100% and car is default set up but this time at Interlagos.
    Exact same AI patterns occurring here too unfortunately.
    From Curva Do Sol down Reta Oposta the AI have insane straight line speed, they fly away or will drive right by me, I out brake them into Descida Do Lago, carry better momentum and racing line but then on the run up to Ferradura they get away from me. Then the next most blatant and strangest boost they get is the traction zone and short straight out of Pinheirinho where they really get away from me.
    The start finish straight where if you stay on the racing line they get closer but then for some mad reason they ease up once you hit the green paint, but if you go to the right of the racing line it triggers them into getting insane speed boosts and they will fly by you, but then I can easily out brake them into T1.
    It really is annoying nailing an apex that leads on to a straight and no matter what, they will either catch you or fly by you, regardless of how well you nail a corner going on to a straight.
