Assetto Corsa PC Mods General DiscussionPC

[racinjoe013]

Dear community i was wondering if there is a way to analyse the texture of a .kn5 file or a way to extract them via content manager

In CM, right click over the top of a track image. In the popup menu, choose manage skins. Hit the plus button in the bottom left area of the manage skins screen and give your new skin folder any name you like. Then click the override textures button. It will bring up a window showing you all of the track's textures. Click the check boxes for any texture you want to extract and then click the override button. This will extract the textures that you want to mess with.

CM LOD generator is failing to make LOD D, any idea why that could be, this list pops up but it means nothing to me! LOd B and C seem to be generated without issue.

This lod that I have seen many times people taking about.
What do they do to improve a mod?

Yes but this works only for the texture of the default track not for those included into an extension

LODs (Level Of Detail) are lower detail versions of a 3D model (in AC, KN5).
Using multiple, progressively lower detail LODs, allows the game engine to render models at different distances, with less detail >> reduced GPU cost. This means the game can draw a 50-car field from your pov, at better, smoother FPS, cos you couldn't see the fine details of the furthest cars, anyway.
AC normally uses four LODs, like car.kn5, car_b.kn5, car_c.kn5 and car_d.kn5.
The distance switching is controlled in the lods.ini in the car's data.

Not a race car yet, but it was raced back in a day in Need For Speed Porsche Unleashed and probably irl too in 60s.
These days its possible to recreate it in Assetto.
Here.

There even is the Cote D'Azur track available (by Xemulator):

Would be awesome if we could get more of those from NFS5.

The AI says:

The Lamborghini Reventón features an active rear spoiler that adjusts to three different positions depending on speed. However, specific speed thresholds for these adjustments aren't widely documented. The car's aerodynamics were inspired by fighter jets, designed to enhance stability and performance at high speeds. If you're looking for precise details, Lamborghini's official documentation or enthusiast forums might have deeper insights.


Are you researching for a project or just a curious car enthusiast? 🚗💨

Oh, for personal and mod related reasons (no I'm not buying one!). Finally found the relevant data... Here, over at the GT6 thread for some reason lol

For that kind, you can put the kn5 file in a temp folder, then open CM. Now go to the temp folder and click on the .kn5 file to highlight it. Next, hold down the shift key on the keyboard, and double click the kn5 file. Wait a few seconds and a folder should popup with a texture folder and fbx file for the kn5 you want to view.

For these steps to work, you may need to have the paid version of CM and have developer options enabled. Been so long that I can't remember if that is the case.

I tried this method but Content Manager gives error

for me in preview they are also black ...
eg:
View attachment 1444278

without CPS it gives white-ish rims indeed.
So redo the previews with CSP option on, then you have the correct same wheels in preview as in game.

Strange though why would they turn black with CSP? I don't have the answer to that ...

Hello. I downloaded this DTM specification and copied the extension folder and it solved the problem.

kn5 is likely encrypted
also, the "temp" folder is not needed. Simply highlight the kn5, press enter and then the shift key directly after, hold shift for 5sec or so

It's needed if you don't want to clutter up the extension folder with extra stuff. I don't like unnecessary files in the track's extension folder. It just confuses me if I go back to it weeks or months later. I forget what I need to keep and what can be removed.

 

[24H]

Ah, I see well. Tried it out but a lot of my cars just spawns weirdly in the preview, Tires pointed in the wrong direction or worse
View attachment 1446079

go into the preview settings and change the steering value to 12.
If the problem still remains, set it to 0.

 

[Rotorist]

If anyone has any idea why the game stucks when loading and because of this the gamepad cannot work properly, I would be thankful for any help. That bug doesn't produce any crash log since it stucks in the loading screen when saying "loading car metadata 100%". I have corrected the faults of car mods btw.

I dont understand at all what you are saying here...

Extracting a KN5 via CM has nothing to do with the extention folder.
You get a new folder called "unpacked-the_model.kn5" with a FBX and a texture folder inside.

Correct. And in my experience, that folder and file get created in whatever folder the original kn5 file is in when extracting via CM. So in @xNAPx case, he said he wanted to extract textures from a kn5 in the extension folder (unless I misunderstood him). Assuming I didn't, when he holds the shift key down and double clicks on the kn5 file in the extension folder, CM will create the "unpacked-the_model.kn5" folder inside the extension folder. And personally, I don't like to do it that way because it clutters up the extension folder. So I move the kn5 I want to mess with to a temp folder first.

Make sense now?

I have seen this when using the standard AC launcher .there is an opinion that this happens because among your machines there are unpacked data.asd.when using Content Manager this does not happen

any super secret tips and tricks to improve CPU performance?

I'm on a 9900K and the goal with this machine is a 20 car field with nu-CSP physics (which are not well optimized by nature, lol, but Ilja seems to be trying with this "hyperthreading fix"). I am due a new PC in ~2 years, and will get a 10800x3D - so hopefully triple digit framerates can be covered off there in the future.

In the meantime, I'm falling just short of that at the start of races - with starts in the high-80s and low 90s, and once rolled away have minor (~2 fps) stutters in battles with a few cars. Nothing crazy bad - but a GSYNC screen can really only cover off GPU-related drops, which I seem to be OK on, even at night. The CPU stutters are minor, but noticeable, and are just a bit annoying.

I have pretty much every CPU "optimization" in general settings checked, and limit smoke and sound. I also use Pure LCS, which from my understanding is worth a few FPS on the CPU side (and may get better, even). But past that, I can't really find anything.

I'm not looking for perfection, I'm just looking for a bit more CPU overhead and a few more FPS at starts so it's not so distracting. I figured I should ask if anyone knows any extra tips behind the hood that only minimally effect the experience.

Cheers.


EDIT: Targeting 1440p 100 FPS lock, forgot to say.

 

[Apocalypse211]

Because of work situation I had about 40 day break from playing any driving sims and continued my 1988 F1 season. It's amazing how much I lost my pace and skills in 30 days. Even a circuit like Paul Ricard felt tough. I needed 1-2 races to get my pace back again.

Anyone else experienced this?

But wow how amazing it was to get back into this game.

PS: Thanks @shi for Detroit 1983. Great work.

@X90
Try to test with and without HT.
Overclock your i9-9900k to 5ghz and check temperatures during racing, my i9-9900KS is at 5,2Ghz and have lowered the Voltage that in combination with PCVR only, optimized Win10, 32Gb high speed DDR4 RAM and the RTX5070ti.
Use software to divide CPU core for AC only/other processes, affinity/pior/forced shutdown. Process Lasso or Bill2 .
Guess you are on the CSP 2.8, maybe the whole version is crapy.
Try to get the knowledge what every adjustment is doing and not clearly see an improvement then lower/shutdown. Better to go hunting for the real ones as you need every droplet for a constant Frametime.
Some mods introduce strange fluctuations, mostly this behavior can be found in tracks/cars that are converted from other old racegames. Also some additional mods/apps can be interfering with CPU frame times.
Disable your Virusscan (as a test).
All those advices from guys that are using a super duper AMD9800X3D/RTX5090 are not helpful, read (recent) advices from guys who are using low end systems. But keep in your mind what runs perfectly on his system could be terrible on yours as there are so many differences in hardware and OS.
Use the OSD tool from CM it give a lot of info on frame time behavior.

Here below a copy/paste from my old post here, old and more Vcard related, but still valid.

Here is my tip on this what’s the best adjustment, because there are so many different hardware it’s for everyone different. My adjustments on a old rig with VR, needs a complete different adjustment then a highend rig & 27” 4k monitor user. Then there is also your personal taste like achieving a stable FPS or in my case get rid of shimmering I do hate.

Read this: tweakguides and lots of info on the guru3D forums guru3D further from my favorites map at: https://stepmodifications.org/wiki/Guide:NVIDIA_Inspector
https://www.pcgamingwiki.com/wiki/Nvidia_Profile_Inspector
I know its about Nividia profile inspector but it’s also contain lots of general info. Because I still think you have to know what you are doing, what the effects are from all those adjustments and is it worth.

Determine what you dislike, as I hate graphical artifacts like shimmer and jaggies. So with the info I have, I’m trying all the specific adjustments on that aspects and see what the effects are.

My test object is btw your (=Racingjoe) ) improved SPA’66 and the Aston Martin Ulster (ACTK site).
I only doing a static test in the pit not a test drive. While in cockpit view I can see all kind of graphical defects that become better/worser, near and at the distance. The AM Ulster is btw a very good car to test as its louvres and front windshield frame are very prone to jaggies.
After finishing that I’m doing a race to check FPS using the CM statistics app.
If being satisfied store your CM pre-selection (video and CSP) settings and make printscreens of your Nvidia settings.

One important thing, if not seeing any improvements from a certain setting I disable this, why using if it only cost you precious FPS. So concentrate on the clear to see improvements setting and skip those maybe setting.

As being a non English speaking person it’s maybe a bit fuzzy writing, sorry for this.

in addition to the other suggestions, try running with VSYNC ON and or limit your frames to 60-61
Also, ExtraFX absolutely kills perf so you might want to turn that off, or limit to exterior only (as I do) if you drive in cpit
BTW, I have a i7-4770 (4th gen non K) with at 1080ti at 4k@60 and get decent performance
