SOLVED!

For those that comes across similar issues... Inside the LFS install directory (C:\LFS for me), you'll find a riftvr log file. This log will have the latest logs from your game session.

In my case I noticed and "ERROR -3009 Graphics adapters do not match between client and service. required: c85e (NVIDIA GeForce RTX 2070 with Max-Q Design)...

This tells me that the game is utilizing the integrated graphics (at least in windowed mode).

My FIX:

1. Open NVIDIA Control Panel
   
2. Click "Manage 3d Settings" on the left pane
   
3. Click the "Program Settings" tab in the main window
   
4. Select "Live for Speed (lfs.exe) from the #1 option drop down (browse to the exe if it's not in your list)
   
5. In section 2, your setting is likely the default "global setting" which uses the integrated graphics. Swap this to high performance and apply.
   
6. Restart the game and now try swapping view to 3D
   

I did not try yet. I have seen the model picture and damn my Xsara ! how is it possible??? I had a 5 doors dark blue and 3 doors white same engine 90hp HDi. I have also tried the TDI gen 1 ànd passenger in the VTS or VTR...
What is an elk test? I did irl the young wild boar test 1500euros worth of repair, The truck tire test even worse (around 3k)...
I will give it a try soon.

make wheels within the limits of what is permitted, nooo ... I will break the LFS editor and throw the wheels on 20k polygons ...

Quote from nacim :

That would make the banning a bit more robust maybe if only accounts that are only 6 months/1 year old are allowed to post on theses threads ?

I would add a certain amount of posts to that as well.
Otherwise people will start creating accounts now (or maybe did so in the past) and can use them ofter 6 or 12 months.
Okay, setting a certain amount of posts can be bypassed as well by giving random reactions to crank up the numbers, but mods will catch that and if the percentage of 'non-reactions' is too high ...

Quote from UniValvePlums :

I wonder if any other racing drivers will sprout from the LFS seed?

Beautiful mod but rly bad that driving it with the steering wheel is really bad!

in the curves you have to slow down really a lot to be able to turn the car ... also by doing this the front tires wear out even if you do a complete turn of the map!

17.5mpg seems to be 13.5l/100km => with the amg cars I had (v8 aswell), it sounds impossible to reach this unless you are on highway driving at a constant speed for a longtime . In normal condition, 16l/100km was quite good by being very gentle. While on highway I could effectively reach 11.5.

Do not know this car model nor even the brand, but it looks nice and sexy ! The seats look very nice !

Have thought for me, I will have electric engines soon instead of the mighty NA v8 ...

Good question but the answer is quite unknown at the moment.

In fact it's not really 10 times the workload, although there is certainly more workload. The current LFS does 'subupdates' within the physics updates. The main reason for that is the wheel object suspended between a strong spring pushing down (suspension) and another stiff spring pushing up, the physics needed a higher update rate to avoid instability in that and I think on some other areas too.

In the public version that subupdate rate is 20 times the overall physics rate. So there is a part of the car already updating at 2000 Hz. In the development version there are 10 subupdates so it's already running at 1000 Hz.

But the ray checks vs world objects (and other cars) only happen at the base physics rate, so that is only at 100 Hz. This part might be 10 times the workload, as you suggest. There is also an advantage in the existing version that the subupdates are done as a tight loop on an individual car so I assume this is good for cache access. I'm sure that expanding the tight subupdate loop into full physics frame loops will be less efficient for cache hits.

Diagram:

Current:

0.00 - Environment check for all cars
Physics update for car 1 (10 subupdates)
Physics update for car 2 (10 subupdates)
...
0.01 - Environment check for all cars
Physics update for car 1 (10 subupdates)
Physics update for car 2 (10 subupdates)
...
[0.02s elapsed]

Proposed:

0.000 - Environment check for all cars
Physics update for car 1 (1 subupdate)
Physics update for car 2 (1 subupdate)
...
0.001 - Environment check for all cars
Physics update for car 1 (1 subupdate)
Physics update for car 2 (1 subupdate)
...
[0.002s elapsed]

I really can't guess how much more work this would be. The environment checks may be 10 times, as you pointed out. I think some optimisations might help with this. The subupdates shouldn't cost any more calculations but presumably will be slowed by memory access as the 'subupdates' are no longer done on a tight loop for a single car.

I think the way forward is to go through the program, adjusting it where necessary so that I can test the two scenarios above with a simple program change (update frequency & number of subupdates). Then test the CPU usage for the physics loop and see how it compares. That sounds simple but as you may imagine, I haven't always put in a suitable multiplier when trying to work quickly to release updates. There is some code around like "do this for 100 updates" which I knew would take 1 second. But now such code needs to be changed to the equivalent of "do this for 1/update_time updates" etc. It shouldn't take too long to get for a first test just to see how the CPU usage is affected. Hopefully it's just a search for the word "turns" and look at each one to see if it needs a fix.

The word "turns" (not case sensitive) appears 671 times
The word "Turn" (case sensitive) appears 785 times

Unfortunately the word "turn" in lower case is part of the word "return" which appears 9687 times. But don't worry, I should be able to devise reasonable strategies to find the relevant lines to check.

Quote from versiu :

U seem to be very closed to any development or opening this game to more people

That is a strange statement considering I'm indirectly responsible for existence of mods in LFS in first place. But I'm not here to brag about it...

Quote from versiu :

Worrying about someone who can judge game basing on mod content is a bit silly

It is perfectly valid concern for a game where vast majority of content consists of mods.

Quote from versiu :

Modders in RBR making stages for years now and it really good quality models and ain't riped from other games. Also in Assetto Corsa there's modding teams who scan road themselves, doing photos etc to make map.

Yep, that's why. Modders in RBR and AC are doing great job and put in massive effort. Meanwhile most modders in LFS take random model of their favourite car from sketchfab, load it in editor and export to LFS. Physics is wonky, lights don't work, shadow does not exist,... Feels like with the editor it is easy to make a mod, but hard to make a good mod.

Don't get me wrong, I'd love to see well made custom tracks in LFS, but what I'm trying to say is - LFS is not ready for community-made tracks. And even less so is the community itself. I've been told how hard to use the track editor is compared to the vehicle editor, we are not ready for it. At least not until LFS modders do the mods at the same quality level like RBR and AC modders do...

post is for Victor too ^^
omg,there is years i delay to post this kind of post .. thanks Rob !

yes, we saw so beautiful night & day effect 2 years ago ... and it make us in a very long awaiting and dreaming about Enduros events simulating 12 hours in 2 or 3h like in AMS2 for example....
and no more news about this dream feature ...

we are races org and last year, there was a teaser about new South City with open roads actually closed and again, we are dreaming about possibilities.

and Mods arrived, that is cool ! and Tyre physics was also in work apparently, so Night & Day and SO seems to be delayed again (yes i read the self excitement with SO in the may2021 progress report)

please, just tell us a approximative date for an update release,even partially , it will be great , the awaiting is literally a torture for an event orga with many planned events.

why not many updates ? AMS2 works like that, improvements by improvements.
ok, you are the bosses, but we are also community who bring life to LFS.. please feed us

please, give us a date .. we are turning mad

Making my way down town ...

Enjoy

Quote from fatalunfair :

Lazy reads memory and that why it goes out of date with every update as far as I know.

ok, we understand ... but is there any possibilities to get these informations in an another ways ?

that is the question of kingofice finally

i used the option "hidden" to release T46 mod before it is finished.
to permit selected users to improve setup or engine.
for me, it is unfair to release a buggued or unfinished mod with too hard handling. so i prefer hide, private access for few testers, collect informations from tests and release later.

unfortunaly, with that method, T46 was not listed by LFStech in his dedicated topic about mod.
so i will not re-use this method for the Nascar wich i work actually ...

but private access has a real interest to release well tested mod.

Quote from lfsrm :

The car general dimensions are fine (compared to other small hatchbacks), it's the car width around the windows/pillars area that are a bit too large, that's why I should've gave some more thickness to the interior panels and narrowed the whole top of the car when I started this project.

it's fascinating how interiors ergonomics expose all the flaws of exterior design !

I understand the comment from versiu : when you put the xf2 next to current LFS cars : it looks very huge

Anyway, the changes done are very good , the car feels nicer, even if the base setup makes it quite brutal by losing the back (clutch pack lsd is increasing the thing). Anyway, as expected, it looks beautiful ... this and the RB4 2.0 are clearly beauties ! Can't wait to have the graphical updates on the tracks to admire these !!

Gum Garage is proud to present and offer "Detect" to the LFS community.
It is the first public release of a GumGarage Tools

"Detect" is a powerfull app conceived and coded by KingOfIce from GUM team.
enterely full insim, it is a very light cpu use and it works fine in VR.

This is a very immersive alerts system. you'll not see your car and others in a helico view ...
you will be alert for near opponents with arrows or triangles system like a spotter.
more the other car is near change the color of the alert indicator !
white : the opponent is approaching
yellow : the opponent is near
red : the opponent is very near ! take care about racing room !

yes, at GumGarage, we are looking for racing room seriously



you can custom your degree of alerts in meters
you can move the display in any place of your screen
you can select beetween 4 display modes of alerts
- a tiny and discreet arrows/triangles
- a massive rectangle
- a dynamique alert mode to follow opponents
- a blip radar like to follow and give distance of the opponents

you can switch off frontview alerts
you can switch off the grey rectangle (used to custom position, and figure your car)

simple to install :
1.Launch LFS
2.type "/insim=29999" anywhere
3.Launch "Detect.exe"
Enjoy clean racing !!

config :
- Win11 : ok
- Win10 : ok
- Win8 : maybe
- Win7 : don't know

the accuracy of the alerts depends on the precise knowledge of the dimensions of the cars.
all official cars were measured by King but the mods had to be estimated. further development of more precise measures is foreseen

"Detect" is the property of KingOfIce.

Gum Garage est fier de présenter et d’offrir "Détect" à la communauté LFS
Il s’agit de la première version publique d'un outil GumGarage

"Detect" est une application puissante conçue et codée par KingOfIce de l’équipe GUM.
totalement InSim , il est très léger en ressources et fonctionne très bien en VR.

C’est un système d’alertes très immersif. vous ne verrez pas votre voiture et les autres dans une vue hélico ... ; vous serez alerté de la proximité des concurrents avec des flèches ou un système de triangles comme un spotter.
la couleur de l’indicateur d’alerte change avec la distance des autres voitures !
blanc : l’adversaire s’approche
jaune : l’adversaire est proche
rouge : l’adversaire est très proche ! attention au racing room !

oui, au GumGarage, nous sommes tres soucieux du racing room

vous pouvez personnaliser votre degré d’alerte
vous pouvez déplacer l’affichage à n’importe quel endroit de votre écran
vous pouvez sélectionner entre 4 modes d’affichage des alertes
- des flèches/triangles minuscules et discrets
- un rectangle massif
- un mode d’alerte dynamique pour suivre les adversaires
- un radar de blip comme pour suivre et apprecier la distance des adversaires

vous pouvez désactiver les alertes devant vous
vous pouvez désactiver le rectangle gris (utilisé pour la position personnalisée, et symbolisant votre voiture)

simple à installer :
1. Lancer LFS
2. tapez "/insim=29999" n’importe où
3. Lancer"Detect.exe"
Profitez de courses propres !

Config :
- Win10 : ok
- Win8 : peut être
- Win7 : on ne sait pas

l’exactitude des alertes dépend de la connaissance précise des dimensions des voitures.
toutes les voitures officielles ont été mesurées par King mais les mods ont dû être estimés. Le développement de mesures plus précises est prévu.

"Détect" est la propriété de KingOfIce.

edit / Detect is now release as part of Detect & Monitor

Mine looked like this:



I have unchecked the box 'Single Page Application' for the ClientID I had, restarted Lapper but it still crashes.
Then I deleted the ClientID I had and created a one without the 'Single Page Application' box ticked.
I've entered the new CliendID and ClientSecret into myinc.lpr , restarted Lapper , executed my code ... and it still crashes.

yes, i tried this, Martin is the enginneer of the T28, and i kept our mp exchange about the T34 similar fix issue
but on T46, redline is already too high ...

Been out of LFS for 2 months just enjoying what life has outside Sim Racing. Have to say I now see why people might not want to attend leagues in the long run - consistency and results...

If I was not capable of reaching points, and had a busy schedule, there would be little incentive for me to continue racing. At least, that's the train of thought I have. There are much more things out there to do.

I believe the way forward is reliable stewarding, regular broadcasts for PR, interesting combos (to circumvent the lack of tracks at the mo)... and a (consistent) set of ballast to bring the field closer together.

That being said, ballast is a hot topic on its own so we have to find other ways to retain the participant rate. Hope someone else shares my point or is able to shed an alternate perspective.

Also with that being said above, Layout Racing League is heading into its 4th season. The first races always had close to 30 racers, but we've been able to maintain close to 20-ish throughout the season. I'm hoping that stays the same this year... New tracks, Indy events and classic combos from Season 1 remain, I really hope LRL S4 can hold its own this year. Props to Jp and Jp2 for sticking with it
