Official General AI Comments & Discussion Topic

NO need to apologise - I hope I was careful and sensitive in my response. I personally work in machine learning and I would certainly relish an opportunity to look at utilising the information you describe. But, this is not available to me (unless i hack the game and painstakingly download a bunch of ghosts). I would love to hear whether it is considered viable or interesting by the team, but don't hold my breath as they have more interesting things to do than entertain my(our?) curiosities.

 

Utilizing a vast array of driving lines generated by users is the approach iRacing is utilizing. Check out how long it is taking them to painstakingly tweak every series and track layout prior to individual release. It also cannot be the sum total of the approach--the AI still need behavioural programming to make decisions in the moment, so the machine learning portion of the exercise is really only replacing the racing lines and corridors part of the "AI package."

Project Motor Racing seems to be taking a ground-up approach using AI...news came out a few days ago about it.

 

I am aware of the iRacing approach, and it is a highly regarded single player experience from what I hear. I never have rented the game, bad internet rules me out of an online experience - I live in the middle of nowhere for good reason, people! Their approach is one that I believe Reiza should look at and learn from. If iRacing weren't so expensive I'd be tempted to try the single player experience...

PMR looks interesting, I sit firmly on the fence, been bitten by Mr Bell and his hyperbole before.

We are blessed with quite a few racing simulations but AMS2 is by far my favourite. I just hope the jank can be ironed out, not that Reiza are doing a bad job, there is an impressive amount of progress already made, but still a way to go with the computer drivers and niggly bugs...

 

Sorry for being "stroppy", spent hours on this combo post 1.6, wrote several detailed posts, reacted to changes in every hotfix, posted screenshots, video, and I wasn't alone doing that. So such a reaction from the moderator was very very weird to see and made me feel like all my contributions were useless or ignored.

 

Indoor go-kart track Speedland 1234. T1, T2 often show multi-car pile-ups against the tire wall, triggering the yellow flag. At this point, from the end of the grid, you can even be the first to cross the finish line.

 

Car: Gen1 GT3 gt4 formal classic
- Track: Silverstone
- AI strength: 100
- Track conditions: dry
- Report: AI struggle at T1, they seem to take a very wide entry into T1 and lock up and spin. This happens nearly every lap, I did gain places as a result but still not ideal

 

Car: Gen1 GT3 gt4 gen2
- Track: nurburgring gp 2020
- AI strength: 100
- Track conditions: dry
- Report: The AI car often suddenly goes into drift between corners T8 and T9, causing it to spin out, and the following vehicles pile up and collide into a chaotic mass.

 

Car: Porsche 911 1974
Track: Kyalami 1976
Ai strength: 107
Track conditions: dry
Report: the AI takes turn 3 with a really wide and slow line

 

Car: Chevrolet Corvette Touring car tier 2
Track: Monza 1971
Ai strenght: 107
Track conditions: dry
Report: the AI uses the higher gear ratio so they hit the limiter too early, about halfway in the straight.

 

are the AI running out of fuel at LeMans - especially in FCY episodes, and hitting the pit exit wall at Daytona Road turn 1 something that is being looked at?

 

Monza Modern - GT3 39 oponents - 120 AI - medium aggro - X1 mistakes - 10 laps

First I couldn't record the race since for whatever reason the software I used doesnt work anymore, so it's going to be just screenshots.
First Lamborghinis still seem to have an advantage in low downforce config, at least at monza they're way faster than anybody else:




The race was chaotic to say the least, 2 FCY in the 10 laps, mostly due to AI losing control at the Parabolica, Lesmo 1 and Ascari when fighting for position. It seems to me like the lines through those corners need some revision, maybe because of the 120 AI?

After the race we can see that the lambos had some big advantge to the rest, the last SC left at lap 8 so that advantage is only after 2 laps, and it seems like nobody can keep up:

 

All the AI drivers seem to never use boost. This results in their low top speed, making them easily overtaken by others.

 

Formula ultimate Gen 2 AI is much faster in the last sector of Spielberg than in the rest of the circuit. AI 105.

 

Can be safely said, every car at every difficulty is fast there!

 

After closely observing numerous AI accidents, I've noticed that in many cases, a single car spins out and then attempts to rush back onto the track, forcing the trailing pack to swerve and triggering chain-reaction collisions.

This pattern is alarming - what should be minor incidents escalate into major pile-ups solely due to reckless re-entry behavior. It's critical to modify the AI's dangerous tendency to immediately rejoin the track after spinning. Implementing a brief waiting period post-spin would be a realistic solution to prevent catastrophic chain collisions.

In all these incidents, GT3 models account for the majority of cases. They have experienced loss-of-control issues across numerous tracks, including but not limited to Silverstone, Silverstone National Circuit, sepring ,Nürburgring GP, Daytona,atlandta. and Oulton Park. and so on.This appears to be a widespread issue stemming from GT3-specific parameters.

It's understandable that some AI errors may occur during the race. The real issue is that whenever a car makes a mistake and makes a hazardous re-entry onto the track, it inevitably causes congestion and forces multiple cars behind it to enter the pits. This significantly undermines the integrity of fair competition.

 

I would like to kindly ask the Reiza guys to check the AI speed on the Buenos Aires circuit number 8 and 9, with all the Brazilian stock cars, GT3 G1 and G2, Porsche Cup, among other categories, because they have much more grip than the player, resulting in a much shorter lap time of course. I believe the real problem is the lack of grip for the player, as I have already done the 2023 and 2024 stock car championships, three times each, and this is the only track where I need to change the AI level to be competitive, and for comparison purposes, I still use Ams 1 a lot, and on the track in question there is no need to change the AI level (in Ams 1, I use 105 with the 2017 stock car), and in Ams 2 for the 2023 stock car championship I use AI at 114. So I ask, please, if possible, to check this track.

 

Add a newly discovered problematic track for GT3 cars: Autodromo Yahuarcocha. In the final S-bend, GT3 Gen1 vehicles will inevitably spin, while Gen2 vehicles have far fewer issues there.

 

At Sebring's final sweeping right-hander, GT3, GT4, and other vehicle classes frequently pile up in incidents – and their lap times fall significantly slower than human drivers
