Re: Make the AI react to tyre temperatures

Currently (patch 1.09), the AIs can ALWAYS keep their tyres at 92ºC, no matter what.

After a pit stop, their tyres are also at 70ºC, just like the player's, but they can easily warm them up back to 92 in about 1 lap - the player needs about 2 or 3 laps to do the same (especially on Hards, which is where this AI advantage becomes easier to see/feel).

It seems - as a general rule - the ideal operating window for tyre temps is from 90 to 100ºC - anything below 90 or above 100 can cause the tyres to lose grip and the car to lose performance (trickier to brake, harder to take the corners, slower to accelerate, easier to lose control, spin, crash, etc)..

They need to simulate the AIs tyre core temps to fluctuate a bit more and sometimes get closer to (or slightly below) 90 and sometimes closer to (or slightly above) 100, which is what happens to the players most of the time - but the players also need to find the best values for tyre pressures, which helps to keep the tyres inside that optimal operating window throughout a whole stint, regardless of the tyre compound (Hards are harder to warm up and tend to be the 'coldest' tyres and Softs are the opposite - Mediums are naturally the middle point between them in this regard as well).

A tip here is to test during the FP sessions and try to take some laps on Mediums and see if the core temps are stabilizing around 95/96 and if so, you found the ideal values for tyre pressures and they should work fine both for Softs and Hards as well).

I'm about to write a whooooole topic about these findings in terms of tyre pressure/temps values - I've found some interesting stuff and I want to share this knowledge with everyone - it might help - I'll post a link to this topic here when it's up - cheers!

    I would guess that the AI always having perfect tyre temperature at 92deg is caused by one of the following reasons:

    a) It takes too much computing power to simulate AI tyre temperature

    b) The AI is not programmed to be able to "fairly" handle high or extremly low tyre temperature -- being either to fast or to slow / error-prone

    I am still on the edge whether I should just go to game settings and change tyre simulation to "surface only" instead of "surface + carcass". That way, you get pretty much the same behavior as the AI has, except you are even a little quicker on outlaps I think because the AI do start with 70* tyre temperature, though it goes up much faster (this is just scripted behavior, not simulated). But this might be mittigated by the fact that you still simulate surface temps, I guess the AI also do not simulate these (but cannot prove that).

    But on the other hand it takes a feature out of the game that I would like to have in there, having to manage tyre temperature seems very important to me for realism. But considering that once you set the correct tyre pressures, you pretty much do not have to worry at all about them for the entire race (except for formation lap and out laps / safety car restarts). 

    Currently though, I am using broadcast mode on safety car and formation lap, which always puts you on level with the AI or at least close. Same goes for flying laps vs. driving the out lap yourself. You are actually at a significant disadvantage when in Qualifying, you choose to drive the outlap yourself, because the tyre temps will be at least 6-7deg lower than when choosing flying lap, no matter what you do.

    This also gets rid of the unfair pit stop outlap advantage the AI have, so it might be a thing to consider, if you are happy only having tyre wear and surface temps simulated.

    I agree with you and these are precious tips that may help a lot!

    HOWEVER..
    It's a shame that us (the players) are the ones who have to come up with all kinds of 'crazy workarounds' to try and fix something that should be working from the start and it's just 'broken' at the moment..

    Once again, I hate to be super harsh, but the truth is that what we have right now is a bad/broken product since it's just not working properly as it should - not to mention we never had these issues (and this much) in previous games - talking about the AIs only, they were never a problem before, but right now they're completely messed up..

    Let me repeat this too: I honestly believe some ideas they had for the AIs this year are actually good, but they were badly executed and they're just not working as they should and causing more problems than making people happy about them.

    I honestly hope the devs can still work to fix, improve and/or adjust the AIs - I assume it's not that easy and simple, bla bla bla - but I hope they do and so the game can be a LOT better, especially for people who love the Career modes (and I tend to believe this is a big number and probably most of the players in this game)..
