December 2023 AI thread ...

NSU @ Falkenberg
Default setup
AI pace @ 100% seems too fast in sector 2.

I can easily get purple times in sector 1 but in sector 2, the AI are pretty much always 0.5 - 0.75 secs faster than me. They seem too fast exiting T4 and consistently seem to maintain top speed through T8 when I can barely achieve that without going off.

 

Hi - haven’t purchased Interlagos but tried it out during the free trial (great, will be buying the circuit after). Found some interesting AI performance:

Categories: GTR3, DTM2023, GTR2 (race only)
AI rating: 102
Setup: default

Issue: compared to other circuits, overall performance compared to mine seems to be too fast for this rating (notably much faster through sector 2 and 3).

Context: normally at this difficulty I’ll qualify somewhere between 50-75% of the field but race pace can match the front of the field (which is fine, good racing - more on that later). But with Interlagos, first tried with GTR2 doing a race (no qualifying), I fell off the other cars losing about 1 second a lap. Figured maybe my fuel load was bad, so tried qualifying and race with GTR3 and found the following…

Driving the 296, Qualified 30/30, 1.2 seconds off of 29th (so way down on what I usually get). I looked at sector times, I could match the AI in sector 1 (I did 23.367, 1st was 23.258; compared to other 296 cars, best placed was 23.457 and worst was 23.491). But sectors 2 and 3 saw big differences. Sector 2, I did 40.792, 1st place was 39.215, best 296 was 39.258 and worst 296 was 39.512 (so I was 1.2 to 1.5 down in S2). Sector 3 was a bit better but still a gap: I did 29.213, 1st was 28.478, best 296 was 28.801 and worst 296 was 28.878 (so 0.4 to 0.8 seconds down).

I wondered if it was just me needing to get good, but comparing my lap time to where I normally come in the leaderboards, I was in similar place I’d normally be on other tracks. Which makes me think that AI seem too quick through sectors 2 and 3 at Interlagos. I’ll try and tweak setup later to see if that helps.

Otherwise, had some great races against the AI these past few days. Great close racing, battles on track and clean racing. Did a multiclass race at Watkins Glen this weekend and it was a lot of fun. Along with two others at Portimao that were great fun (and also visually looks good with the upgrades here). Good work all involved!

 

FR X-22 @ Silverstone GP
Default setup
AI pace @ 100% seems too slow

AI is very slow in the middle sector, particularly through Becketts.
They're also a bit slow going through Luffield and the final chicane.

 

AI pace is a little off:
The car class (AI selection): GT4
The track layout: Circuit Zolder GP
The AI Strength setting: 103%
Your qualifying time versus AI qualifying time: see attached image below (this was a practice session)
Your race best lap versus AI pace: see attached image below
Description of how AI pace is off:

As you can see, although the lap times overall look correct, when looking at the individual sectors we can find some inconsistencies. I've been having trouble catching up with the AI in S1 since I started learning this track, and at first I thought their pace was way off in that sector, but then I saw that I was doing much better in S2, and about the same in S3. So I chased one of them and I saw that the problem was at the Villeneuve chicanne. Apparently, they brake too early at Villeneuve, and then exit too slowly at Terlamenbocht (if done correctly, you can gain a lot of speed on that exit). Also, they could carry a bit more speed into Bloderbergbocht.

So my impression so far is that their pace needs to be 5 tenths slower in S1 and 5 tenths faster in S2 to be consistent.

I will post the qualifying and race results if they reveal a different behaviour.

 

More information on this last report.

The behaviour described above was clearly observed in practice. Then, in both qualifying and the race, the AI found the missing tenths in sectors 2 and 3, but absolutely obliterated me in S1. The exact spot where they gained a remarkable amount of speed was at Lucien Bianchi's corner. It's not easy to keep the momentum there, but they manage to blast away from that point. The problem is that this can cause an accident against a human player, as was the case. Halfway through the race I was hit from behind because one of the AIs came up so unexpectedly fast that none of us could avoid it.

Other than that, it was a very good, exciting experience. Yellow flags on the first two or three laps, close racing, daring attacks on position, good defence.... I would have taken P17 if it wasn't for that one hit, so very good job by the AI in the GTR 4 class!

I attach images of lap times to document it.

Qualifying

Race

 

I did a FR-X 22 race at Silverstone and the AI (difficulty 108) is too slow at the corner entries of The Loop and Luffield. They are too fast at Stowe.

Is there a rough date for when the next AI update will be made publicly available for us to test, try out and report back?

 

There should be a bigger update in late August / early September.

 

Moskau (FIM) mayhem, last turn onto start/finish straight AI (almost) always crashing into each other, even worse with Multiclass grid (GT3/GT4).

 

I did a FR-X 22 race at Spa and the AI (difficulty 108) is way too slow at the chicane and La Source. They are too fast at Double Gauche (Pouhon).

Spoiler: Track map

 

AIs are too fast in the following corners
Slovakiaring turn 2
Salzburgring turn 11

This has been an issue for way too long that, the AIs are blistering fast through these corners whether I am racing on 95 % difficulty or higher. Here you always likely to get annihilated by the AI like getting overtaken on the outside of both the corners. It happens with every class I tried but mostly noticeable with GT3R.

What you did with the Road America annoyance at the "carousel" is just what these two corners need in the patch and the worst parts of the tracks are fixed!

 

AI prone to accidents:
The car class (AI selection) DTM 2016
The track layout Lausitzring DTM GP Course
The AI Strength setting 97

AI hits very often the wall in turn 1, causing yellow flag and pile-ups

 

For example Silverstone Spa racewayGP 。。。。Almost 80% track have this problems
The AI car will all be in fixed corners, lose control and collide with each other almost every lap the same
This seriously interfered with single-player matches
Hopefully it can be resolved soon

 

Mid Ohio Full
WTCR 2019
Adaptive AI

AI are struggling at turn 1. They are coming in too fast, cannot take the turn, going well off track to the right and then flying back to the track sometimes spinning and sometimes not. Yellow flags on every lap.

 

I noticed this as well, if you use the GP layout instead of the DTM GP layout they seem to be fine as turn 1 is not as tight in that layout.

 

I did another FR-X 22 race at Zandvoort and the AI (difficulty 112) is too slow at Hugenholzbocht and Hans Ernst Bocht. They are slightly too fast at Scheivlak and Mastersbocht.

Corner: Acque Minerali

AI losing the rear end and spinning on entry to Acque Minerali causing a big pileup, happened 4 laps in a row.

 

Something is off with the AI, and I’ve highlighted this before with Group 5. Since the tyre update, which is now a while ago, the AI are ridiculously fast, and unrealistic. I raced today with DTM 2020 (BMW) at the Red Bull Ring grand prix circuit, difficulty 90!!!. The fastest AI came in at 1,21,309, which for diff’ 90, is totally nuts. I checked the leaderboards, for this combo, and the fastest time is 1,22,447. This can’t be right, that at this diff’ level, the AI are that quick. It’s one of the reasons, why I stopped playing RR3. The AI drive like they’re on damn rails; in particular in fast turns they have grip levels that are just not normal, and there is no way to compete. Can this be looked into, or will it be addressed in the next update? Thanks all…

 

AI no fun in Raceroom.
Every track i play and every car AI at slow corners they are very slow and sometimes they almost stop there. On fast corners their tyres seams to have glue to the track and off they go.
So when i race ( AI at 97%) no fun, at slow corners i get them and pass them, them comes a fast corner here they go......No close battles.

 

Tried racing the carrera cup germany 2023 around spa gp but the ai just lose too much time through the bus stop, la source and eau rouge sections. On 111 strength they lost up to 2.5s through there compared to me and then made that up again by being much quicker than me on the rest of the lap, especially pouhon and stavelot 2. Lap time wise they were roughly where id want them to be but i ended up winning after having started from p15 because i could just overtake them and then mostly keep them behind fairly comfortably
