Assetto Corsa PC Mods General DiscussionPC

[NivekBS]

Optimization, pals, optimization...

Since there are combinations of tracks, cars, and environmental conditions that work and look spectacular (or at least, to my taste) and others that make even the best PCs falter, I think the blame lies with poorly optimized mods, not the game itself (although yes, has limitations)...

This is the price to pay for the freedom for anyone to tinker with the game, sometimes with a lack of knowledge or putting personal tastes before the requeriments recommended by Kunos pipeline.

(Yep, I know, I'm a pain in the neck... 🫤).

I stopped with CSP 179
No csp physics, no AI „improvments“
Everything is running perfectly @UWQHD with a 3-4 years old system. If I can’t run some few cars - well let’s be so.
I am happy with AC as ever

[Apocalypse211]

I'm trying to simulate the 1995 F1 season (Using this mod) - The mod needs you to download the 412T2 seperately, but I've noticed that the performance seems slower compared to IRL (Brazil Round). Top qualifying times at Mo were taken by a Benetton, at 1:15, while the 412T2 qualified best at 1:19 - Putting it slower than even the backmarker teams.

Is it best to just give up on this 1995 mod or is there some kind of fix?

You can't really take one particular track out of the blue and say the cars are wrong. That track might have a bad fastlane. You don't say what track you used. However ACU Interlagos and Shi's 1992 ASR tracks both have good fastlanes.

It's very difficult to balance the lap times for all 16-20 tracks in the season. For example I adjusted the 1988 SD traction lower and more realistic, the cars crashed all over the place. I had to keep a bit exaggerated traction and compesate that by increasing a bit of aero drag in order to keep them perform correctly on most tracks.

I'd say their laptimes are almost spot on at 11 tracks out of 16. In Spa and Monza for example they're dead on accurate +/-0.5 seconds. But then they're a few seconds slower on Monaco for example. Nothing wrong with 1988 Monaco track fastlane... it's just how the cars are designed.

The most important part in the season is that the individual drivers perform correctly. The 1995 season was a two drivers' deal: Hill and Schumacher. If you want to make the season realistic I strongly recommend using the championship.champ file and define both Schumi and Hill ai level to 100.

You can't emulate, say, Hakkinen's McLaren unreliability to the game. Well you can actually... I experimented that a lot with the 1982 cars.. you can create ai engine failures but those cause bad traffic issus on AC. You just have to make the "second tier" cars/drivers Berger, Hakkinen, Coulthard etc. at level 94 or so. Of course Hakkinen was a top driver but his car reliability was total garbage (10 DNF's) so his AI level should be around 92-94'ish.

Most 90's F1 seasons were two-driver battles and those two should always have a significant ai level advantage over others in order to achieve realistic results.

If the ai drivers/cars are generally slow compared to the user/driver (whatever driver you're controlling in the game) you can always go to your car data and the easiest way to make relative performance changes is the CD gain. You can easily give the AI cars top speed advantage there. Of course this doesn't work if the season is skin based (and uses only 1 base car). Decreasing CD gain is the easiest way to make AI faster without tinkering the driving feel at all. I have no idea what those 1995 cars are but if the cars are actually too slow, that is a good trick to increase the overall performance too.

Test with another track and see how they perform in that one.

As I am not a fan of the 3d trees but this track desperately would need some proper ones. Maybe @MoriSan77 you could think about this as next?

 

[MasterFocus]

AC in 2025 currently looks like jenga -they've added so much stuff it's unstable as hell and if you take one bit out you're afraid that everything will crash down lol

(That's what happens when you add things to a decade old engine that barely supports those uh)

We don't expect 4K gaming, we expect rain races that work (they barely do) and night racing that doesn't require a NASA computer to run (good luck) but surely it's not Ilja's fault, nah, it's us peasant unwilling to buy the latest computer to run a game from ****ing 2014 lmao.

Say what you want about AC but it is everything but optimized. I have no problems running night, rainy races in AMS2 but my computer struggles for AC ? Yeah it's not the fault of the game uh.

Just run the vanilla game then! Or any other racing title that dont support modding like AC!

Guys, if you hate AC so much, then what the hell you do here!? Since last week it seems every 3rd post is for whinning about how bad ac is!

I've tested with the Spa 2022 kunos mod and I definitely think something is up.

In the actual race, it qualified 1:54 on average. In game, it qualifies around 2:00 on average.
Again, the Benetton got a 1:55 in game (1:56 IRL)

Maybe I'm wrong. I'm using the 2022 layout, which has likely been changed since 1995, but I don't think It's changed all that much?

You seem to have added the Delta textures as the 'default' in the skins folder, rather than as a selectable skin, making direct access to the original textures difficult without some jiggery-pokery. Much better to keep the original default textures as they are and add the Delta textures as a selectable skin in case anyone prefers some (or all) of the originals. I personally prefer the original tarmac textures over the darker Delta ones, for example.

Yes that is slow. How did you qualify? Are the ai cars seconds behind your lap time?

Why not use the 1998 Spa? Brilliant fastlane, accurate layout, no garbage modern ads.

Just a couple of suggestion:
- it's better to put the updated textures inside "acu_india\texture". If you put them in "acu_india\skins\default" they will be deleted when another skin is enabled.

- to have a better water add the following lines to ext_config.ini:

[INCLUDE: common/materials_track.ini]
[Material_Water]
ACTIVE=1
Materials = water
Type = POND
RainOffset = -0.5 ; Water surface will lower when there is no rain water

Are you serious, Easy?

It's the sad reality of creating mods in 2025, no matter how much time, effort and passion you put into a car mod, the moment you encrypt it some people will go ape****. Most likely because they can't rip it apart, claim faux-ownership through meaningless "changes" or "fixes".

I've become very much pro-encryption over the past years, having seen my older car mods (which weren't encrypted) get broken apart and sold on 3D model sites for exorbitant prices. Just last week I had to take down a 3D printable version of my T33/2 which some jackass was selling for 30USD online. Several of my old Japanese prototypes are on similar sites being sold to this day.

If you're not satisfied with certain aspects of the mod or want to see bugs fixed, just communicate to us via the proper channels so we can get them fixed, it's not that hard mr. Easy!

I'm not good at that.

 

[Quark67]

Just move the textures inside "acu_india\skins\default" to "acu_india\skins\cm_skins\Delta7Fox" (you can change Delta7Fox something else).
In this way you can choose between the original and the updated textures.

It’s become way too common in the AC community this past year. I’ve been sharing the Mustang work on Discord with a group of people, and the first complaints I got weren’t even about the 3D model or anything like that. It was about the fact that I’m encrypting the 3D model and selling the non-encrypted version (with permission from the creator), just so I can hopefully recoup some of the commission costs and put that money toward the next 3D model I want to commission.
One guy even went as far as to say he’d just buy the unencrypted version, share it with everyone, and then do a chargeback. Only in the Assetto Corsa community

Unfortunately many individuals aren't receptive to changes, so ripping is the only way. I told RSS that the buldges on the F10 cockpit were too big and that they weren't supposed to be like that, showing how kunos who had access to CAD data from Ferrari did the cockpit section.

After swimming through all the fanboys who came up with all sorts of excuses like "onboard has fisheyes it distort the perception", the "RSS used end of season F10 spec your picture shows early season" and finally the "it's not because codemaster, kunos and polyphony digital did the buldges small that it means the F10 had small buldges", I've been told by one of the RSS guys that CAD data given to manufacturers are often low quality and not really representative 1:1 of the real car. And that their measures is correct.

This is way too big for reference it's supposed to be a bump on the car not a buldge.

Completely ruins the car for me. On onboard view the F10 from RSS looks completely ridiculous.

Ended up ripping their F10 to fix it myself even though it's encrypted, i may have lost all the "flexible sharkfin" feature and any bones related animation, but its gimmicks that are not enough to compensate for the ridiculous onboard look of the car. Spending that much time trying to create a faithful representation of an F1 car and priding themselves that they have done a never seen before masterpiece full of features just to shag off legitimate request is not a minority by far for people who encrypt their cars. That's why I'm against encryption.

I disagree, AC runs better on my spare machine with a GTX 1070 than AMS2 and LMU do, by quite a fair bit, and looks better to boot. Pretty sure all I did as far as tweaking the CSP settings was disabling extra fx too, I didn't really mess with it much. Even on that weak machine I don't tend to have stability issues. In my experience CSP works well but occasionally is subject to odd settings issues. I could see people who are unable or unwilling to troubleshoot things having substandard results with Assetto due to this.

Just run the vanilla game then! Or any other racing title that dont support modding like AC!

Constantly criticizing something isn't generally productive but neither is toxic positivity.

Which csp you use? I remember Ilja fixed the blurry previews with csp 0.2.7. The filter being used for the previews is the default filter and you don´t have a possibility to change it, it is kind of hardcoded in csp.

using csp 0.2.12.preview1 ... (also downgrading to 0.2.7 didn't fix it )

And when I change the "default" (Default.ini) PP filter, my newly generated preview does not look any different...
would it really be "hardcoded" ... ??? (I can't imagine someone would choose to do that when PP filters are available as ini files... )

please Ilya can you change it so that the current selected PP filter from the active Video Settings preset is being used?

This is from an encrypted car...
No cockpit_hr, lodA YUGE!, only loda, texture not compressed...
Cant even correct any of those for my very own pleasure since its locked behind encryption, so does a LOT of encrypted cars.

I'm yet to read any hate towards AC on here, or anywhere honestly, i guess its quite sad that we are fast approaching being like the GTR2 guys still plugging away.... fact remains, there is still nothing like AC at all after it. You have to go backwards to find anything close and thats GTR2 / Rfactor 1....

As an aside its funny how these GTR2 modders are so funny on their forums about people taking their mods for AC, yet there are loads going back from AC to GTR2...that's is all fine of course..

AC is such a great canvas to mod in though, that's why i will stick around in it for a long time yet to come, the only thing that had alluded me was the drift culture, and now i finally got bitten by it and its ace fun, having an absolute blast and you literally can go wild with the modding side and create some mad stuff.

It´s not that you should change the ppfilter and the preview image is different then. It´s hidden in the folders of csp. Believe me, I spoke a trillion times about this with Ilja but recently there was no effort to change (or to be able to) change the pp filter for the previews. Have you tried switching to a different showroom? Is the problem still persisting? I don´t have these issues and I believe 24H hasn´t them as well, so there must be something weird with your settings.
