Assetto Corsa PC Mods General DiscussionPC

[ninezeroniner]

I also had problems with my RTX 4080 Super with a newer version of the Nvidia Gpu driver and so I'm still on 566.36. No performance problems so far on my side. But I have really a highend PC.

Welcome to the Nth AssettoCorsa+Csp fatal showstopper that is kept secret because we all deserve to suffer under the shadow of the randomest simulator ever.

Thanks Frank25, I owe you one. Or two. Or more.

Say hi to the DTM 2025 grid, picture sucks but yeah, I'm basically dangling it in front of all you all GTPers in a phallic fashion.
Sorry.


Grids with CF's cars are fine too.

My Nvidia driver is 576.28.

Nice but...fps drops for me, from 120 to 15 😓

If you experience such drastic fps loss, ALWAYS open CSP Lua Debug app.
It will tell you if there are errors. The newer mods today using lua scripts.
So it should be the first look there and you will see, that it caused by it. And mostly it is caused by older CSP version, which not have the functions or parameters which are called in those lua scripts.

And the big fps loss is caused by the lua system then itself. If there is an error, the system changes to a failsafe state and this will gain the CPU consumption tremendously and so fps goes down...

You can also try to change the CSP settings "Limit audio" and "Limit audio for other cars" under "GENERAL PATCH SETTINGS/CPU optimizations" to reduce the number of used audio samples.

Little participation to the thread, i made a Suzuka 60s better fastlane for sergio loros/rainmaker's track. It 's a lot better on my end, although still perfectible.

Also since i'm gonna be off for the summer there are my pet project graphic attempts (scripted ppfilters and reshade presets) from the last month. Everything is in the vid description here

Also, i'm looking for the best Porsche 911 or 930 mods, trying to get into supercars from the 80s lately, if anyone has a grid in mind let me know !

I'm looking for some feedback from this fantastic community about a modder that I stumbled across (All Along The Racetrack) on Patreon. Are these tracks any good?

You could try reducing both of the "FADE" options in the ext_config.ini to a lower number. That usually helps with the performance. I left it at the default settings so you may have to adjust around with it.

FADE_AT = 500
FADE_SMOOTH = 150


Gaming at 1080p at a lock 60fps with same old 560.94 Nvidia driver update that I had since August 2024 could be a factor on my end

Hi Peter, I opened it in one of the moments when I have the fps collapse but I don't know how to interpret, I took a screenshot.

@Perico Lospa
For those who wanted to know, I play at 1440p with fairly high settings despite a 3070ti graphics card, practice mode, only one car, I go from day with 120 fps and if I set night it becomes 15fps.

@MeltFire
I tried lowering the values you suggested, but they didn't help..

Has anyone tried this config file?

 

[Carpocalypse]

Does anyone know if there's a replacement to AC Simple Championship Tracker by MK-SG? There's a issue with team view I reported a few weeks ago, and it seems that they're no longer active.

May I ask for an updated link (@MS6Driver)?
Abt's TT-R is one of my all-time favourite racing cars, but other mods are lacking.
Thank you!

Mine looks worse and not a clue as to why: From CM // miscellaneous // SHOWROOMS (running CSP 0.2.11)

View attachment 1462111

I have a similar problem. I have followed all instructions (but I have installed other showrooms, is not the first), but this is what I obtain...

Any ideas?

P.S.: the car is not encrypted, it happens with all cars.

 

[ninezeroniner]

Yeah, DTM '95 and '03...
what happened to them, I thought models and skins were there or almost there then all went silent.

Normal to see the showroom like that for this one, but it should generate correctly when you make the preview provided you have the option selected to use CSP for preview generation.

 

[StoffelWaffle]

I have a request for @Apocalypse211 : could you, pretty please, make a 2008 skin for RT's infinitely better version of Fuji ? MTS' is pure unoptimised **** lol

If you are the "owner" of this site, you should put the "DOWNLOAD" button in another color so its easier to find, even tho its always at the same spot!

I had the same issue. Try this adjusted preset, plus drop the models.ini in the TAV_moderna showroom folder.

Does anyone happen to have a RainFX config for Chang International Circuit?

Final attempt to adapt a Lancia D20 Compressor (Le Mans 1953). I think it turned out better than the others. Later on, I will do tests on the track with other cars from the same year.


First tests ( Jose Froilan Gonzalez )...for now the "right fog light" is not working.

hello very good work !! when will share it ? thank in advance

is anyone making the 1995 dtm mods?

 

[MrLonguinha17]

I intend to do a test with other cars (Le Mans 1953) on the track...to make a "BoP" suitable for the season (as I normally do with other seasons).

Yes 512 is the best setting. Tried changing it to 1024 and it was worse. That's why I said that AC has problems with anything over 512. Maybe Ilya could take a look if anything could be improved. If any of the people here is in contact with him.

I did an easy test, took out 24 of stock new RSS ferrucio's. Then changed the sound of the car in CM to the sound of some other car, I think I took chemmflummy sound, took the same 24 cars out and the frame rate improved drastically. So it is something to my logic.

Never knew this!

And it's made a really nice difference! Just changing the channels to 512 in the ini definitely helped with the lows and stutters, even with CSP limiting sounds to 3 cars.

Previously, the lows at the start were in the high-70s and low 80s - now, they're in the ~88-92 FPS range at starts, and even out towards my target 100 after just a few seconds.

The stutters are still there, but considering they happen on collisions and when I can see AI cars going over kerbs, I assume it's just the CSP spaghetti code overloading the CPU. I can see that my CPU3 is getting absolutely hammered - while the bottom 8 cores are at less than 15%.

Such is the state of AC - hopefully that "hyperthreading fix" for CSP eventually becomes more fleshed out.


Still though, really nice shout with this recommendation.

Was giving these audio changes a spin, and I've found out that my AI on Magnificent Park now has a problem - the AI brakes in the middle of the back straight for no reason.

The only thing I've changed is the CSP version since I've worked on this (0.2.8preview, now 0.2.11preview). With the AI app open, everything looks just fine - there's no crossing of sidelines or anything out of the ordinary. Disabling the New AI Behavior extension does nothing.

Has someone else ran into this issue before? On this CSP or otherwise? I'd prefer not to have to roll back to test.

Give my AI a spin (click on my username and then Resources) if you'd like. Obviously, I didn't just brake in the middle of a long straight on my AI line lap - so something must have been broken in the background.

Try fully extending the Render Stats menu app. It shows your CPU/GPU performance, bottleneck and FPS loss.

The first image shows how Riverside performs with no lights (0.01 CPU ms usage)

With the lights are turned on it shows a 0.06% CPU ms usage and 5.2 FPS performance cost. (Which would matter if I'm using an unlocked frame rate) You can also see my CPU/GPU usage when up from 18.1% to 19.7%. another good indication is those little color graph bars next to the stats numbers. (Green = Good) it varies from computer to computer.

My rig
CPU: i5 - 14600k
GPU: RTX 4070 Super
Nvidia Driver: 560.94
1080p 60fps (Using old 60hz AOC monitor)
-
CSP: 0.2.12-p1
PP Filter: PHOTOreal (Some filters heavily affect performance, I just really like this one)
Nearly every CSP setting left at default.

re: Lights perf

A few things can help, you can add this to a lights statement

SHADOWS_HALF_RESOLUTION =1

Also be aware of cluster threshold

Both [LIGHT_...] with mesh and [LIGHT_SERIES_...] with meshes split their meshes into groups.
The basic principle is simple: 
starting with zero groups, for each vertex, find nearest group. 
If it’s closer than certain distance, add it to that group. 
Instead, create a new group. That threshold distance can be controlled:

CLUSTER_THRESHOLD = 10  ; distance in meters

Minimal value is 1 meter. Please check how many lights are actually being created:
lower values might spawn too many lights, and all of them take time to render.

Have you tried changing the car? I occasionally get the AI slowing and stopping on some tracks in spec races using certain cars.
It's all part of CSP's rich tapestry.

yes, sorry, forgot to mention. tried with the URD Oreca, the RSS NSX, and the Kunos Porsche Cup car.


All three of them were test cars when I made the AI (with the Oreca being the feature car), and worked fine. All three of them now slam on the brakes in the middle of the back straight. Must be a backend issue.

There's so much nonsense with AIs and CSP. I remember not too long ago, there were multiple versions in a row where it was Russian Roulette as to whether the AI would get off the line at all...

I suppose I'll report it on the CSP Discord.
