Track layouts to receive AI line redos

Nurburgring GP 2020:

In Dunlop hairpin, AI in front drives extremely slow/brakes at corner exit instead of stepping on the throttle again. A complete braketest. AI from behind therefore attacks player like crazy, just steering in blindly.

They generally do that in almost each corner of the track. Going in too fast in front of player and then going slow/braking at exits.But in the hairpin, it is the worst.

Above that, they drive completely insane through last chicane when player is near.
In order to avoid being overtaken, they just jump over the sausage curb every time, lose control by being airborne and ram player off track. They would not even step back there when player already is cleary ahead. .
Just like they fell in some kind of rage mode when player is around.
Driving there in a pack of AI in an open wheeler is one of the most horrible experiences I ever had in this game.

Edit: It is a general issue in AMS 2: AI in front braketests player whilst the one from behind goes for a blind attack. They do not behave that weird when racing each others, just when player is around them.

 

Just did some testing at Pocono, and had interesting results. AI always at 106 and on Medium agression.
With Stock USA, the AI is a little too fast on the exit of T1, extremely slow through T2 (especially on exit) and a little slow on T3 entry. Same results across all 3 gens, though I'm still learning how to properly drive the old cars, so more testing would be ideal, just don't have the time for that yet.

Then I tested the F-USAs, in the 2023 the AI was so chaotic I couldn't even evaluate it properly. But on Gen2 and 3 (didn't have time to test Gen1) I had genuinely great racing. First time I left an oval race in AMS2 thinking I could actually include it in a championship if I ever do one on those cars.

Still had some issues though, consistent across both Gens 2 and 3: I need a perfect exit out of T1 to match them, but it is possible. I'd say they are a little too fast there, but being very nitpicky about it. Now, they were very slow on the exit of T2, but only on the exit. Unlike the Stock USAs, they were fine on entry. And finally, they are very slow on the entry to T3, perfectly fine on the exit.

 

the AI keeps running the inside banking when they are trying to overtake at Bathurst 1988 T6

 

I don't know if this post belongs here but it's concerning AI at Daytona NASCAR Tri-Oval. It's not about AI line but more about pace.

Track: Daytona NASCAR Tri-Oval
Car: Stock USA Gen2
AI settings: 113 strength, high aggression, default mistakes
Player setup: default (fuel 52 l)
Issue: AI is relatively slow in the kink before and at the start and finish line. It seems as AI lift off a bit during that kink for no reason (no car in front of them, no danger of collsion). As player you can take that corner flat out.
Other than that AI do a great job at the rest of the track. They drive as one would expect them to at 113 strength.

• Test Race, off camera: First corner, first lap, AI ran on the inside grass

Steps to reproduce: Watch the video in the laps mentioned above

 

Watkins Glen - GT3 / LMDH.
The AI brakes far too late and is way too fast on the brakes into Turn 5 (Outer Loop?) and is extreme slow on the exit. As a result, accidents occur very frequently in that corner. I usually let them pass me on entry and overtake them on the exit again each lap..

 

Spa 1993:
AI attack the high curbs all the time. Driving open wheelers, they often get airborne and flip the car.

 

Track: Kyalami Historic '76
Vehicle(s): F-Vintage G1
AI Strength: 120
Aggression: Medium
Mistakes: Standard
Sessions: Practice, Qualification & Race

Observations: AI currently losing time in certain corners that are resulting in uncompetitive times at the highest AI strength. I have identified (2) main problem areas that I believe could be better served with minor line/speed adjustments. The quickest lap I've seen from an AI at this setting was 1:18.20.

T3- Jukskei Sweep: AI is off throttle too long heading into the sweep, causing a very narrow exit. This costs them acceleration towards sunset and often bottlenecks traffic behind. User overtaking is too easy in this area due to the AI's slow pace. Cost Estimate: 0.30-0.40

T9- The Kink: AI lifts (off-throttle) into the kink and attempts to over-correct their line towards the middle of the road. Users can overtake multiple AI opponents here during races. During a previous race, I was able to over take 4 on exit, as they all lifted, then overcorrected to the middle of the track. This is probably the largest time-loss area for the AI, as they lose all their momentum on the straight. Cost Estimate: 0.50 (much more for trailing AI in the bottleneck).

I did a quick AI qualification test video so you can hear the off-throttle and slight over-correction behavior (overall time not indicative of what is currently possible for AI at 120). I think with minor fixes to these (2) areas, the AI could get into the low 1:17's and will be much more competitive at 120 Strength.

 

Kansai GP:
In qualifying, AI on fast lap have no idea how to overtake those on their inlap, just crawling behind them and pushing their rear in different kinds of open wheelers.
This leads to huge trains and weird results in qualifying.

 

Montreal Modern:
V_V10 Gen 2
AI cuts corners in order to overtake player and has magic grip all around.

 

Donington National:
Turn 1, Ai cutting a corner..
