So anyone have noticed a bad intelligence when opponent cars enter the pit??

Running GT World Championship on the Professional hall, the AI seems to not think on how many laps the races have!!!

There you go to a 16 lap race and you see your tires getting orange on lap 8. So you think "I am on the middle of the race and maybe it's a good idea to have new tires to finish it". You enter the pit, change your tires and get back to the race. Then you notice your start driving much faster than the opponents and on lap 11 or 12 they all start to enter the pit.

My only conclusion to that is: there is no intelligence on the ralation between race distance and tires/fuel consumption!!! The opponents just wait until the tires get to an 'impossible to drive' state and then pit. You can see the cars running out of the track, braking into walls, etc.

My assumption, GT4 AI on pit strategy doesn't exist. :scared:
 
My favorite is when they pit on the last lap of the race and their pit box doesn't let them cross the finish. LOL
 
When I first attempted the GTWC (I think) I was beating the other cars but my tyres started to go off and when I pitted I was miles behind. So I quit and tried again. And again. And again. Only when I was thrashing them with the F1 car did I realise that the AI opponents were waiting till about lap 7 or 8 to pit! That really annoyed me.
 
The pit strategy of AI cars is a good as their ability to avoid immobile objects.

I spun out on the Ring last night and was hit by the 2nd place car broadside at around 150MPH.

If there was any sort of collision ability at all, he could have gone around me.

Stupid AI.

It is fun when the last lap pit give you the win though...a little cheap, but it is just playing the game.

Completely agree. The cars seem to have a pre-configured braking point for each curve. Maybe a relation between current speed X distance to the curve. They simple ignore obstacles. Thats why they simple get out of the tracks when the tires got worse :yuck:

I had a similar experience the other day. Driving my Minolta around the ring giving my B-Spec guy a good headstart for the 24 hour race (I went to Donington for the BTCC 👍) I span out on the tricky left hander at the top of a hill and ended up across the track. I reversed across the racing line and bam! i'm sliding at 200Mph into the Armco on the opposite side of the track :ouch: . The only car that didn't hit me was the Spoon S2000 because it spun out on the left hander and skidded to a halt in-front of me. :grumpy:
 
Unfortunately the AI hasn't improved much since GT3. :( THat's sad. And a big miss for PD. I hope Enthusia is better, I've heard Enthusia is better, dunno, isn't released here in Europe yet.

But wasn't paying much attention with the Seoul F1 race. I let my car pit one lap later than normally, to prevent he would pit 2 laps before the finish. But forgot to change the order to pit, and he pitted one lap before the finish. That's rediculous. Pitting in the last lap or so.. That's not realistic at all. :rolleyes:
 
Another thing to notice is that the AI Always refill their cars upto full.

If you're running in B-spec... wait for an AI to pit and switch to their car and watch them pit...

You can watch their fuel gauge fill up to full!! (You can't end the pit stop though!!)

I can stop my girl (b-spec) to pitstop! what wrong with her? she's good, even i got A-spec 12,000 and she got 3,000, but still good work in 24 hours (it's her FRIST race on 24 hours and won 6 laps 👍 👍 ) she's good... WHAT WRONG WITH MY GIRL????
 
I have also noticed how much like a brick the AI cars are. I mean they can bump you off the track, but if you are both going down a straight, they will just run you off the road. Also if you ever Tbone a car thats mid turn, they will recover way quicker than they should. I have given up playing dirty in desperate situations because it never works.. but that dang MacLaren SLR spun me out many many times during the Nurburgring race Legend of the Silver Arrow.
 
you sure about that?

i remember being able to run a car off the track just fine in one of the driving missions and i easily won despite the 5 second penalty.
 
The AI is lousy as far as pitting goes, like everybody else confirmed.

I was B-specing the Fuji 1000KM for the R92CP and I noticed the XJR-9 pitted really inconsistently (sometimes like 6 laps before everybody else) even though later he went almost the same number of laps as the other guys!
 
I have seen an AI opponent who was 10 seconds ahead of me enter the pits on the final lap. Doh! The computer has a lot of trouble trying to control cars with bad tires, I've seen them spin out often.
 
They also have trouble on the ring and la sarthe estimating how long their tires will last. I will happily underestimate tire wear and pit a lap earlier than I need to if it means that I don't risk cherry red tires. The AI has no concept of course distance and average tire wear / mile of course - you would think this is pretty important course knowledge (you know, that one might gain with the course knowledge skill points?), and in endurance races, it could mean much better overall time. I hate my b-spec driver for his stupidity, but I love him for when I leave him on all day.
 
Some of the races are satisfying or f%$"**g annoying on the last lap or 2. On the 1st race at Opera Paris in the dream car championship i was catching a Ford GT well fast before he pitted on the penultimate lap and ruined a good climax. Yeah, it does kinda spoil the action. :grumpy:
 
I was doing the Nurb 4h enduro in the Ford Falcon XR8 V8 supercar, and the two NSX's in the race (at one stage) kept spinning out, because of worn tyres - one did a 11 minute lap :dunce:
 
i was doing two laps round nurburgring in a black LMP car, a nissan, not the r390, cant remember its name
but yea i aspec'd the first lap, then let mr b take over for the second lap, i ended up being 20 secs behind a 7878B. i passed him halfway through the lap, because i found out in the replay, his tyres were rubbished and he was spinning out
stupid ai, should have pitted, but im not complaining, i won the race
 
i notice that in b-spec, b-spec bob wont pit until the tryes are red and theres no fuel :scared:

im b-speccing the 24hour ring now and noticed that he pits every 5 laps with red tyres and 1 bar of fuel left :scared: and then every 20 laps he misses the pits alltogether and goes half way around the ring at 50mph with no tyres :scared:

i just let it do that now, theres no way im staying up and telling him to pit on lap 4 all the time :crazy:

so very true, especially in B-spec mode wen your screaming at the playstation to overtake the car in front.. *pulls hair out*
 
I realise that if you stop refueling at say the half tank full mark then it saves you time in the pit stop, but does anyone definitively know if the reduced weight of fuel is reflected in vehicle performance?

My guess is yes, in the formula champioship I usually couldn'y get beyond sixth place until after the first pit stop when I wouldn't refuel at all, after that I kept the tank half full at pit stops and from then on I was generally able to work my way up the field with faster times as well as reduced pit times.
 
Did anyone watch the European F1 GP yesterday? If Kimi Raikonnen were a GT4 AI driver he would've pitted on or around the last lap. I'm not saying that the AI in GT4 is capable of flat-spotting tires (or even just wearing them inconsistently) but it's nice to see that even in RL sometimes a car needs to pit near the end. Makes the stupid AI a little less annoying...maybe :sly:

HAHAHA very very well said.. thats pretty much how i would sum things up. I dont think it would be possible to do the 24 hour races without him. The sheer boredom of repetitve'ness would make muh head explode.. ( or implode.. im not sure)
