Assetto Corsa PC Mods General DiscussionPC

[Masscot]

Post any CSP issues in the relevant section of the shaders patch Discord. Ilja might see them there and action a fix. I doubt very much he reads GT Planet.

 

[FrustratedUse]

Found two skins for the AC Re Work Renault RS01 that is real liveries. It should work with any mod that are using the Project Cars 3D model without an changed body mapping. I don't know who made them as they were just labled 01 and 02 in the folder. If anyone knows lmk and i'll proper credit them or take it down in case they don't want it shared.

In my case, I don't think that's the solution, since I don't believe it's a problem with the different volume levels of the effects, as most of the cars sound fine. I suspect it must be a feature implemented in some mods that doesn't work well with certain CSP settings. Furthermore, I try to minimize the use of add-on applications that might conflict with future versions of CSP and create problems that didn't exist before.

Anyway, thanks for the suggestion; any help is welcome. 👍

Did you look in Settings/CSP/simulation/audio?
There are a couple of options that can help:
"Use interior sounds everywere"
"mix in exterior sounds"

The truth is, since this only happens to me occasionally and only with certain mods, I took a quick look without changing settings too much, so as not to mess it up, like usually...

I'll try to experiment with those settings as soon as possible, thanks!

This is an issue on CSP side as this happened after the latest update, and this also happened few releases ago. We just need to wait for a hotfix

AC has its issues but man I tried PMR (since it's free for the weekend) and even for free I think I got swindled pretty hard

I'll never bemoan AC again lmao

Hi everyone. This might be a silly question: with the new scalers, can I use only DLAA (i.e., without DLSS)? And how do I activate it? Thanks.

Well, good news then... AFAIK you can't use them at the same time

Question on behalf the DLSS 'installation challenged':

Should I install Optiscaler to get the best results with DLSS, or is the nVidia DLSS package all that is required? I'm running an nVidia RTX4080 Super.

I now have DLSS running properly, with the nVidia DLSS option selected and no Optiscaler installed, but would I get more (and even better) options if it is installed? As everyone knows, we always want more!

EDIT: After reading Peter Boese's comment below, I guess I can forget about Optiscaler altogether.

EDIT 2: Wow. I'm very happy with the way everything is looking (and feeling) now. Unless something truly astounding turns up, I can't see myself needing to buy another racing sim for a long long time!

It’s better if you think of it as an arcade racer with multiple setup options. But I cannot recommend people go and spend their money on it.

Have you downloaded the latest DLSS? You can download here DLSS. It's a compressed file, unzip to Assetto Corsa root folder, should say "nvngx_dlss.dll" then. Now try again (after your advised reboot). Let us know whether you were succesful after this.

The addition of DLSS to Assetto Corsa (AC1) is a game-changer, and as of March 2026, it is officially available through the latest Custom Shaders Patch (CSP) updates. Since the original game engine doesn't support DLSS natively, CSP acts as the bridge to inject it.

EDIT #1: Below are instructions how to set DLSS in CSP (Latest)
EDIT #2: Seems the "nvngx_dlss.dll" needs to be in :/assettocorsa/extension/internal/ folder... (I thought in root folder, but hey, I'll will check this too...


Here is how to set it up:

1. Requirements​

• NVIDIA RTX GPU: You must have an RTX series card (20, 30, 40, or 50 series).
  
  
  
  
• CSP Version 0.3.0 (Preview 338 or later): At this time, DLSS is primarily available in the "Preview" builds of CSP. You typically need to be a supporter of Ilja Jusupov (x4fab) on Patreon to get these cutting-edge builds before they hit the public "Recommended" release.
  
  
  
  
• Latest NVIDIA Drivers: Ensure your drivers are updated via the NVIDIA App or GeForce Experience.
  
  

---

2. How to Enable DLSS in Content Manager​

Once you have installed the compatible CSP version (by dragging the .zip into Content Manager and hitting install), follow these steps:

1. Open Content Manager.
2. Go to Settings (top right) > Custom Shaders Patch (top left).
   
   
   
   
3. On the left-hand list, look for a new section titled Upscaler (or check under Graphics Adjustments if "Upscaler" isn't its own tab yet).
   
   
   
   
4. Set the Active Upscaler to NVIDIA DLSS.
5. Configure your settings:
   • Upscaling Quality: Choose from Quality, Balanced, Performance, or Ultra Performance.
   • DLAA (Deep Learning Anti-Aliasing): If your PC is powerful enough and you don't need the extra FPS but want the best image quality, look for the DLAA toggle or set the mode to "DLAA".

---

3. Fine-Tuning for 2026 (DLSS 4.5+)​

Since the latest updates now support DLSS 4.5/5.0 features:

• Ray Reconstruction: If you are using CSP’s experimental Ray Tracing features (like Screen Space Ray Tracing), ensure "Ray Reconstruction" is enabled in the DLSS settings for much clearer reflections.
• DLSS Swapper: If you want to use a specific version of the DLSS DLL (e.g., forcing version 4.5 into an older CSP build), you can use the DLSS Swapper utility or manually drop the nvngx_dlss.dll into your assettocorsa/extension/internal folder (though CSP usually manages this for you now).

4. Pro-Tip: Check the "Extra Effects"​

DLSS works best when combined with CSP's Extra Effects. Go to Settings > CSP > Extra Effects and ensure TAA is disabled if you are using DLSS, as DLSS provides its own superior temporal anti-aliasing.

file needs to be in "...SteamLibrary\steamapps\common\assettocorsa\cache\binaries\dlss", but, i cant make the optiscaler work this way. any help appreciated

Try this (below) and let us know whether you were succesful in getting DLSS/DLAA to work.

no. it didnt work. right location is what i wrote above. i renamed the dll and game redowloaded it to where i described. so something wrong with lightspatch. doesnt download optiscaler and if i manually put the opitiscalr to that location, it fails to read the version.dll file. i think we'll wait for ilja to fix.

Afaik, if you run on nVidia DLSS v310.5.3.0 selected with Quality DLAA (100%) mode, you would only need this as the DLAA is in fact running at 1x, so there is no upscale left to do with this option.

I run it myself with L option activated, which should give a bit better quality compared to K. This last option L is said to be at low cost (like 5-10% ) compared to K as it is optimized for RTX40.. and RTX50.. series, especially if running at 4k resolution.

Using this with a sharpness set to 10% , very happy with the results so far

ExtraFX is active?
Video Single Screen mode is used?
NVidia GPU?
any dxgi.dll in use?

Because you should not care about optiscaler, it should work with default usage. So i guess there is no fix in general for CSP, but something is not fitting on your side.

Might be an dumb question, are you running very recent or perhaps very latest NVidia driver package (596.02)?
Not all GRD or NSD drivers are compatible with DLSS. Just a thought. I run 591.74 NSD (Studio)

But I'm struggling too to get this working to be frank...

I will check this my end too:

1. video Screen mode is used? (@Peter Boese are you refering to DXGI in CSP? Should I put this OFF or explicitely ON?
2. any dxgi.dll in use? (Run CMD add tasklist /m), look at acs.exe and or AssettoCorsa.exe

Sorry, i meant Single Screen mode in AC video settings. DXGI does not matter, i tested DXGI HDR mode and it also works in HDR.

I'm very happy with the results too. It's amazing how a program that began its life in 2014 can be made to look this good 12 years later.

Peter does it work (DLSS) in VR or single monitor only?

 

[Ken134]

Hi All. Is anyone having problems with VR. With all CSP versions over 0.2.12 crashes as soon as it goes into VR. Tried latest CSP Nvidia drivers ect. On latest Pure. I use Openxr with a Pimax light. Any help please. I have reported to Ilja. Many thanks.

 

[kpcart]

Before i try dlss/dlaa in AC (im scared changing too many settings will make me forget my currently good settings, csp already has way too many settings), does dlss make the game look any better?? that is what some of the comments seem to imply. I have tried dlss in some other games, and it usually increases frame rate at the expense of picture quality. so what is the deal here with dlss on AC?? i have a 13 year old i7-3370, and 6 year old 2060rtx, and have never had problems running AC, with csp/pure at 1440p and around 60 to 80fps.

Hi Ken134
im using a crystal lite too and OpenXR toolkit with open composite .
no problems here , all working fine with the latest CSP build.

 

[timetoo22]

DLSS to my mind is that you are using presets which will reduce the resolution but then upscale to native. Thus more FPS.
For example MSFS 2020 I can use DRS to run it at 4k res, but use DLSS to reduce res but it upscales then to 4k, that way i resovled jaggies. My TV isn't even 4k, it just works to make a better image at less cost.

So to my mind regards AC you could do the same idea, run at 4k then use DLSS to reduce the cost but still get a crisper less jaggied image.
Actually in my case AC looks ok anyway and i don't need 200 fps so not really much point in using DLSS for that. But i will try the MSFS method for sure...

It works wonders for Cyber Punk also, I just am not sure that people can say it makes AC look better, it should really mean in this case a RTX 2060 can suddenly have more frames available than without, question then is, did you need them?

Just save every adjustments in CM, and then see for yourself. As everyone has it’s own opinion based on different hardware. Seeing your PC Hardware I think DLSS will be a nice addition, but on the other hand why bother if everything is according to you running great.

My advice: Do not fix what isn’t broken!

 

[kakauiyt]

We don't need DLSSLop5 in AC though. Unless you want a yassified version of your car...

edit : new CSP is great but there's a funny bug also present in the previous CSP iteration : broken ass flags at Aldo Scribante (CrisT86 & Pugsang version) lol

DLSSlop5 might actually make it worth it driving acfl cars

no

You have to make everything in blender, including making the driver seat correctly in the correct space location. Because once exported it's not compatible with CM Showroom for moving the driver around.

i'm wondeing if the DLSS/AA topic shoud be moved to a new thread?

 

[Peter Boese]

Single monitor only for now.

Actually it makes the picture absolutely clear, no jitter or anything like jagged lines. So it is the best AA so far. But at the cost of fps.
It introduces some other artifacts, but those are ignorable. If you want a super clear image, it is the way to go if you can waste some fps.
You just need to activate ExtraFX (you can set "exterior only" it will still work but you don't have the fps loss of extraFX in interior cams), you need to set it in CSP graphics adjustments and then you just set MSAA off, nothing more!
