Official General AI Comments & Discussion Topic

- Mini JCW / Virginia (full)
- AI 100/80 (same happens in 100/50)
- Race session in all default values (time, setup, weather (clear) etc)

- T11-12, "Oak Tree", the very slow double right hander before the back straight. AI is extremely slow on exit, can pass 3 of them in that spot and in next straight in every lap of the race.

- T16b - 17, "Hog Pen", last corner before the start/finish straight. In this case, the AI has too fast exit speed, nothing extreme this time, but very noticeable when compared with every other spot in the track

- All other corners seem to be well enough balanced

 

A general observation: AI laptimes spread is very small, around 0.3-0.4s, regardless od strength and aggression setting.
27AI cars, all G40 cup.
Tracks driven@AI strength:
-Brands Hatch Indy@90, 88, 85
-Cadwell@86, 87, 89, 90, 92
-Oulton Int. & Fosters, both@90, 92
-Donnington nat@90, 91
all with G40 cup, aggression setting: 80, 70 on Cadwell.
Here and there the AI laptime spread is a bit larger, 0.5-0.8s, but it is very rare.

 

Car / Track used: pretty much every car / Adelaide
AI Strength setting: 103-107
Corner (if issue is corner specific): turn 8
AI Aggression setting: 90
Session Distance: any
Weather when the issue was observed: cloudy but also any
Player Tyre: slick
AI Tyre (if known to be different from player):
Type of session when the issue was observed (practice / quali / race) all

AI are always slow on exit of turn 8 and brake mid corner making the easy targets into 9 but then if you get along side into 9 them they can turn in on you and hold the turn even after inmpact causing cars to get stuck.
I have video of the Ai turn in if needed using the 2019 Stock car.

 

When filing a report please include the following information relevant to reproducing the issue:

• Car / Track used: F-Reiza / Spa
• AI Strength setting: 120
• Corner (if issue is corner specific):
• AI Aggression setting: 50
• Session Distance: Qualify 10 mins
• Weather when the issue was observed: Clear
• Player Tyre: Soft
• AI Tyre (if known to be different from player):
• Type of session when the issue was observed (practice / quali / race): Qualify

Issue: AI performance in qualify is completely off pace. I am 1.4s faster than the fastest AI at the strongest level, which absolutely makes no sense since I'm a very average or even below average driver. This issue has been reported before (one or two builds ago) for the F-Classic Gen 3 class.

I've read througout the forum quite a few people regarding the AI as awesome, but I'm starting to believe they aren't racing open wheelers. Or maybe... should I give Toto a call?

Nice!

So I was probably trapped in a loop of frustration: I would always use the first session to gauge the proper AI strength to race with. If the AI was too slow, I would quit the session and increase strength. If it was too fast, I would quit and lower strength (lately this has not been happening though).

 

• Car / Track used: Formula Gen3, Formula V12, Formula V10 Gen2/Kyalami Historic 1976, Estoril
  
• AI Strength setting: 99
  
• AI Aggression setting: 70
  
• Session Distance: 30 Minutes
  
• Weather when the issue was observed: Light Cloud
  
• Player Tyre: Hard Slick
  
• Type of session when the issue was observed: Race

Description: The AI either does not experience slipstream, or it is simply slower than me in a straight line, or it slows each other down in unrealistic ways in battle packs (braking a little while going for moves), probably all three. I can easily overtake several cars on the long straights.

 

Reporting back on this:

• Car / Track used: F-Reiza / Spa
• AI Strength setting: 120
• Corner (if issue is corner specific):
• AI Aggression setting: 50
• Session Distance: Qualify 10 mins
• Weather when the issue was observed: Clear
• Player Tyre: Soft
• AI Tyre (if known to be different from player):
• Type of session when the issue was observed (practice / quali / race): Qualify

After Renato's tip the AI lap times are much more competitive, however AI is likely off pace, since once again I got pole position and I'm a below average driver:

​

Maybe AI is not deploying KERS?

Edit: my lap time here is better than previously because I was not aware DRS zones were available in Spa (saw no boards before and still don't see them, only noticed it after AI in front of me opened DRS).

 

It's a shame you can't adjust AI in a session or at the end of it ready for the next session as AI seem to be faster or slow a bit from track to track or from class to class. I can imagine it would be very difficult to code in though.

 

• Car / Track used: Multiclass with P1, GT3, and GT4 classes (I was in a Ginetta P1, All classes affected for this report) / Spielberg modern
  
• AI Strength setting: 99%
  
• Corner (if issue is corner specific): Whole track
  
• AI Aggression setting: 100%
  
• Session Distance: Race weekend with practice / qualify / 20 minute race
  
• Weather when the issue was observed: Rain during practice (qual was dry and no issues) and rain started halfway through the race (2 weather slots, first was heavy clouds second was rain)
  
• Player Tyre: Wet
  
• AI Tyre (if known to be different from player): AI pit when I did (most at same time, some a lap later) so assuming they took wets
  
• Type of session when the issue was observed (practice / quali / race) Practice and race (qual was dry so they were fine)
  
  Keep in mind for the description below, when I say AI I mean all classes listed above.
  
  During the practice the AI were extremely slow (set to rain, rough estimate: about 2.5 - 4 seconds slow for the AI setting) During qualify the AI were at their normal pace. During the race they were at their normal pace in the first half but once the rain picked up and they pit for wet tires they began to drive extremely slow around every corner. They seemed to have decent speed on the straights but they were braking very early and taking all corners at a very low speed (~45 mph average for the P1s) Once they were on rain tires in the race they seemed to be driving at the same pace that they were driving at in practice.

 

• Car / Track used: German Group A - both cars (Mercedes 190E and BMW M3). Problem seem to be with all tracks. I've just tested Cascavel/Jacarepagua/Londrina/Interlagos/Donington/Montreal
• AI Strength setting: 100%
• Corner (if issue is corner specific): Start line
• AI Aggression setting: 100%
• Session Distance:
• Weather when the issue was observed: dry
• Player Tyre: dry
• AI Tyre (if known to be different from player):
• Type of session when the issue was observed (practice / quali / race): quick race

AI cars are much slower to get up to speed off the start line than the Player car. Starting from last in a field of 20, it's always too easy to make up numerous places before the AI cars get up to speed.

NB. this is not sim-racing notorious T1 issues, it's the AI speed off the start line.

 

• Car / Track used: all tracks
• AI Strength setting: 85%
• Corner (if issue is corner specific):
• AI Aggression setting: 50
• Session Distance: 1 hour Practice, + 1 hour Qualif
• Weather when the issue was observed: dry
• Player Tyre: dry
• AI Tyre (if known to be different from player):
• Type of session when the issue was observed (practice / quali / race): practice, quali

I adjusted the AI to be about my level, 85%.
I run a one hour practice, followed by a one hour qualif. From the first lap I returned to the pits so that the AI could drive the car.
After an hour, and in fact from the start of the practice my AI is about 1.5 seconds faster than the rest of the AIs.

The same goes for qualifying

I'm starting the Weekend again, and this time I'm setting the AI to 100%.
This time the lap times are correct, my AI who drove for me and the rest of the AIs are running in the same lap times.

So I think there is a little bug, which is that when you use the autopilot, its level is at 100%, even if the AI has been set to 60.70 or 80%. Autopilot should be aligned with the rest of the AI I think.

I tested this on several tracks and several cars and I had the same result all the time.

I did this test to be able to see the evolution of the track, but did not want to do an hour of practice myself.
