Then we got a moza shifter that will autoblip on downshifts.

Hm... looks like that solution is outdate anyway?

I think the more realistic thing is that Pubstats hasn't been updated in 12 years. Not much need for it as it's fairly stable of a feature.

First one, I tried to change S_PLATE_ALP to different mode, from ALPHA TEST and TREE EDGE ALPHA, whenever I exit from modeller, it resets to ALPHA only, is this bug or what?

This one might be just a LFS rendering quirk with regards to multiple surfaces requiring alpha blending

What do the option "Sleep every frame"? It have no effect. I guess CHatGPT-4 described me his option wrong.

The GPT-4 description isn't too wrong. It's basically an intentional delay where LFS does nothing to allow other processes to do something. Less of an issue on modern multicore systems as there's 2-32 "cores" (cores + hyperthreaded cores) available to carry out tasks.

@Scawen:

Stupid question (because I have no idea about the technical implementation): Why is it not possible to create/generate such an AI path in multiplayer as well instead only for single player?
Is that planned (on todo list) but too time-consuming/complex at the moment?

Huh that gave me an interesting idea. Have people locally generate their own AI for a mod and then join an MP race and race their generated AI paths. It'd be interesting to see how "identical" they'd be or if there'd be differences.

Quote from NewDriver96 :

Hello there,

I have the V3 Advanced FX (Dale) steering wheel and pad and it has the vibration mode turned on.

However, in the game there is no vibrations.

Is there a setting that I have to turn on in order to feel vibrations?


Thank you for your help

LFS only supports force feedback (rotational output), not vibrations.

I have it installed and I guess it works for AC (in the rare times I use AC). I use iRacing's native LFE as it is entirely derived from physics rather than telemetry like the ButtKicker one is.

HaptiConnect isn't something required to use ButtKicker, it's just a first party centralized app for sim integration => effects generated from telemetry => bass effects being output to the correct device.

LFS could implement its own bass effects and allow you to output it to a 2nd audio device (like iRacing does) and you still don't need HaptiConnect or SimHub to generate those effects.

Quote from farcar :

I figured as such.

Of course, my next question is whether anyone has a way to get the LEDs working on a CSL DD Base?

I can't see the dash clocks with my FOV, so they're important to my setup.

It doesn't seem like there is. Fanalabs is the official app for it but doesn't seem to support LFS.

Quote from farcar :

Apologies for the massive bump, but wondering if FanaLEDs is still supported?
I can't get it working with my Fanatec CSL DD.
It seems to detect my Clubsport Pedals but not my wheel or display.

It doesn't seem like it's been updated since 2021 so it might not support the CSL DD (and newer hardware).

No. Forever ago the training AI (which were slow) was replaced with a new AI system. We can see with the mods that it is able to quickly iterate an optimal race path in a short period (30-40 seconds)

For the longest time I basically had a set of scripts to do just that with the F9-F12 menus.

Quote from rane_nbg :

Isn't the following update release with "new lighting + new tire physics" including day and night stuff?

Sorry yeah, it's 1 patch. But at this current point it seems like Scawen's more or less "done" with the day/night stuff and has transitioned his efforts to finishing the physics

Quote from chaitany :

when is the day and night update dropping out?

after the new tyre physics

also probably will require a paid licence too for dynamic day/time

The AI in the game aren't very intelligent and have little awareness of other cars. You'll have to drive considering that fact and take preventative measures from them hitting you.

Quote from davidtaurog :

oh that sux,I wish it has normal transmission.thank you for answer and advice,I will try that.

Interestingly generations of the FBMW that we have does have autocut for upshifts. The one that LFS simulates just has a less technological gearbox in it.

Quote from davidtaurog :

well it is hard to shift gear up or down,very laggy and sometimes it doesnt shift gear at all.all other cars work normal.I got momo wheel...help!

The transmission is a sequential but doesn't have auto cut. You need to lift off the throttle to shift up. One thing you could do is basically hold the upshift paddle and then lift off the throttle to engage the next gear.

Downshifts should be easier as the gearbox will be under less load but you can't downshift too fast either.

Quote from Scawen :

As mentioned in another post, I've had an initial look and made some notes about converting LFS to 64-bit. I don't see any real problems but a lot of lines need to change. Initial thoughts are it might take a week or two, which puts it on a low priority compared with tyre physics. I can't really think of any short-term benefits at the moment other than allegedly it's the only way to connect to OpenXR (which I've barely heard of and obviously would have to code for as well).

Anyway, maybe you could tell me what is the difference or connections between OpenXR and OpenVR and SteamVR?

I thought that the aim of OpenVR was exactly what you seem to be suggesting is the aim of OpenXR. But as far as I know, the only implementation of OpenVR was SteamVR? But thought that didn't have to be the case?

I must say that OpenVR/SteamVR has been really fantastic in providing a way for many games to connect with many headsets. Has its time really come, and why?

I could go reading and researching but thought you might give me a short explanation (if you feel like it).

Things have just kind of evolved with OpenXR being the standard supported by all vendors. It's a standard owned by Kronos Group (OpenGL, Vulkan) rather than an API owned by Valve.

OpenVR was first to market that could be freely implemented and practically every headset does support it (to varying degrees of performance) and Valve has done a decent job of making it freely usable, but it's ultimately an API that is proprietary to Valve and their needs.

As you know, OpenVR/SteamVR does provide a freely implementable VR API and headsets are either native "OpenVR" or vendors like Oculus/WMR have provided plugins to allow their headsets to operate with OpenVR. One downside to OpenVR is that it does require Steam as SteamVR is the defacto standard implementation of OpenVR.

SteamVR also functions as the OpenXR runtime for most OpenVR headsets (although some ship their own OpenXR runtimes).

For Oculus, they've already deprecated their own API in favour of OpenXR and have shipped an OpenXR runtime that performs very well. Using it is as simple as setting it as default in Oculus settings.

For other headset vendors (Windows MR, Varjo), they're also shipping OpenXR runtimes that allow applications targeting OpenXR to function natively with their headsets, not requiring SteamVR to run applications.


Now, because there are so many applications written to OpenVR/Oculus API, 2 projects exist to translate those to OpenXR on the fly. OpenComposite does OpenVR => OpenXR (originally OpenVR => Oculus) and ReVive does Oculus API => OpenXR (Originally Oculus => OpenVR). For many people (myself included), one benefit to OpenXR is the ability to use OpenXR toolkit to further refine things to optimize for comfort or performance.

Now I don't entirely think that targeting OpenVR/Oculus only is bad, but OpenXR is the future and in the few apps I've used that are native OpenXR, there's some valuable performance gains from the reduction of SteamVR/Oculus overhead. But using tools like OpenComposite to give LFS OpenXR support is perfectly fine.

For OPs issue, it seems like their headset doesn't support OpenXR in 32 bit applications as they aren't shipping a 32 bit runtime. For my headset (Reverb G2 running on Windows Mixed Reality), Microsoft ships both a 32 and 64 bit runtime (64 bit in \Windows\System32\MixedRealityRuntime.dll, 32 bit in \Windows\SysWOW64\MixedRealityRuntime.dll) and expectedly OpenComposite works with LFS.

Via SteamVR which adds unneeded overhead.

OpenComposite lets you skip SteamVR and run OpenVR API games in OpenXR directly with improved performance.

OpenXR is the inevitable "stable" API for VR. Oculus has deprecated their own API in favour of it and both SteamVR and WMR offer OpenXR runtimes (great in the latter case as it skips SteamVR).

It's going to be more common on laptops where technology like nVidia Optimus (https://www.nvidia.com/en-us/geforce/technologies/optimus/technology/) or AMD Switchable Graphics where an low power GPU (AMD iGPU or Intel iGPU) are paired with a high power dGPU (nVidia or AMD) that gets dynamically enabled when needed.

Unfortunately on Windows, the dynamic switching isn't very intelligent and gets it wrong and often you have to go and tell the GPU to use the dGPU either all the time or just with a specific application via the control panel.

macOS did a much much better job at dynamically switching GPUs but now Apple doesn't even ship any multi-GPU machines.

Quote from PopnLochNessMonster :

I am all for this feature. How would it be decided what setup would be the fixed setup? Some default setups that cars come with are just bad to race with.

Server specified setup.

Quote from Avraham Vandezwin :

Remembrance tends to magnify things. I doubt we find the AIs of yesterday's games very fantastic today.

I remember watching a fairly recent video testing the Iracing AI patch. It wasn't brilliant. Worse than in LFS (I haven't tested myself).
Programming a good AI is certainly very complicated. What's unfortunate with LFS AI is that it doesn't seem to be missing much to it to become acceptable.

Bad AI = disappointing first test of the game = no motivation to practice = no need for demanding driving = humiliating and unpleasant first online experience for others = (also) no competitive bots to complete grids = empty servers online = an offline practice that quickly becomes boring.

Sometimes some of the things that seem inessential are fraught with concrete consequences. Afterwards, it's easy to say (and always ask for more) it's another thing to roll up your sleeves and do it.

iRacing's AI is very very good tbh. It takes a bit of time to find the right pace for yourself, but it's really good at being a competent opponent. Respects your space, makes overtaking moves, doesn't barge you off track. It's actually useful as a training tool for real races.

Yes it'd be nice to have a fixed setup option. Of course some settings would need to be open (like brake bias and some steering config) but having a mostly locked setup would be good.

Quote from FIZ :

They are on a higher level, indeed.
Cannot say for all of them, but even GT5 has a much higher AI intelligence.
AI on LFS have to be enhanced, I remember discussing about it around 2003-2005, because even 2 decades ago that AI was barely acceptable.
Please, everyone, look around more.. it is clear just by looking at some youtube videos.

Then you go and play GT7 AI and realize it's so deficient which is why the game only makes them mobile chicanes while you time trial as every event. Actual racing against them is impossible.

Quote from Flotch :

as a student it was more convenient to play online from time to time ... now, it would require a bit too much time to achieve any capability to drive properly a given combo .
Taking a car with a kind of default setup and doing few laps anywhere is plenty of fun, but usually I have to end quickly for "family life" or so on => short cruise sessions are satisfying (even if I agree regarding the multiplayer aspect : doing short races of GTi in the time around Blackwood was insane )

Honestly this is basically why iRacing "works" for me. I pick a car for a season to practice and run and only run that series. Then I can practice when I can and run a few races whenever and be guaranteed to get a race.
