You're mixing up my comments some referenced AC, other PCars. You seem to be attributing them all to PCars.
Anyway... Like I said. I've got over 400 hours in the game. And there are tons of videos online of people showing those problems. If it works for you. Great! Have at it. I only play it every once and a while these days, and consider it more eye candy than anything. I'll wait for PCars2.
Also... if it were as good as you say. It would have more community support and league play. But it doesn't because a lot of leagues gave up on it.
No i didn't mix up anything, i think the other poster mixed it up...
For me it is not only eyecandy, but also a lot of fun to race against AI...i use some mods that up the game of about 10% at least though (crew chief and FFB mod that definitely puts it on par with AC).
I have never tried it myself, but i learned that the online mode from Pcars is bugged. I have never bothered to try out, because AC has always been my to-go sim when it comes to online. That's probably why there is not so much league play (there is though, i know numerous sites out of my head that organize league and club racing for Pcars)..
Yeah... AC is what I was referring to. In PCars, they're far more aggressive. If you're not well alongside them when you reach the braking zone, they will turn into you.
So just like it is in real life?
I raced the AI in PCars with x3 tire wear in a FA race. Something seemed odd (the AI wasn't pitting, even though my tires were well worn). So I restarted and set the race to 50 laps. 22 laps in, the AI still hadn't pitted for tires. Does that seem right to you? 66 laps on a single set of tires?
And yes. I've played PCars since the last update. They stopped supporting it in the latter half of last year, so if you've played in the last 6 months (roughly), you've played the latest build. The tire model hasn't been changed in even longer.
Here are few (recent) comparison videos. This guy does a good job of showing the differences.
I think he has one that shows him setting near identical lap times in fresh, overheated, and completely worn tires. I just couldn't find it. Might be another reviewer. But the first video does deal with tire temps around the 6:00 min mark.
It definitely does not seem right, and i often heard that you can adjust things the AI can't cope with - same as it is in every other Sim i have encountered so far, even the Raceroom AI still needs fixing in some areas, that can be exploited (or it exploits you).
I am not a bug hunter however. I just wanna race normally, and set everything normal. Pitstops normal, tyres, fuel, all normal. And when all is normal, the AI behaves normal (a very good "normal"). In all the races i have done in 80 hours with club cars, street cars, GT3 cars and karts, only the superkart AI was bugged. So i rushed through it with 10% races (making career), and having fun since then without encountering any issues..
Tyre wear seems absolutely normal for me, if not a little exxagerated..the difference from worn tyres to new tyres in the FFB is almost a little extreme. Last race, which was my first GT3 race in the career, i spun twice, because the tyres were so bad in the end of my stints, and i just didn't expect it. Both the AI and me set the fastest lap times around 15 minutes after the pit stop, after that the worn tyres had a bigger negative effect, then the less weight had a positive effect..was the same for AI and me. So while i acknowledge that other people encounter oddities in this area, and there may be videos out there that "prove" some errors (i know that some people changed core code from Pcars though, and then made fake videos, only to shade it in a worse light, so i wouldn't interpret any youtube vid as proof for anything), in my game version on my computer all seems right, and i have a lot of fun. That doesn't mean that there aren't sims out there, that makes things in a lot of areas better.
For
AI racing though, my first two recommendations are definitely R3E and then Pcars, in that order. Those are the (only) two sims i see worthy to race against AI.
I also use F1 2016 for AI racing, the AI there mostly is also very good and challenging. But you absolutely have to enable rewind function, because sometimes they just divebomb you like mad. One rewind, and act like it never happened. Then you can also have quite some fun with the career mode.
