Assetto Corsa PC Mods General DiscussionPC

[Peter Boese]

Now that we're entertained with the launch of Asseto Corsa EVO, it would be useful if, when someone comments on the fps achieved with a certain graphics card, they also add whether it's in VR or monitor/s, and what resolution we're talking about... I think it's interesting to know so we can make comparisons.

I also tell you that I don't really give a ****, since for now I'll remain faithful to my beloved and ailing original Assetto Corsa.

And now, my usual stupid joke:

The explanation...

...and my mind trying to understand it.

VAO is like a tool where you build a map with an external programm. It uses a light which is strait above the map. And then it will process like a shadow map. So on this map all parts that are completely litten by the light gets a 1.0 and all parts which are not litten att all gets a 0.0.

So later in the game this map (VAO) is used to multiply the ambient light value for every pixel. And the higher the ambient light value is, the more the difference is of places with a high occlusion or a low occlusion.

And in Pure the daylight multipier is a direct multiplier of the ambient light value. So if both are high, the difference of the brightness of an area with a high VAO value is really high compared to an area with a low occlusion.

RTX3080, triples at 1440p. 110-120fps. I used the Nvidia and most in-game settings found here and got a massive boost (yes, advertised for VR. but worked for me).

Very soon, all mods will get a final update.

F1 2007 : this mod state was absolutely SDD level, it will get an update to get close to 2008 quality level

F1 2008 - fixes

F60 ferrari : Fixes too

F1 2010 : New williams steering wheel, some shaders update, new skinpack and also you will be able to get the sharkfin version of both virgin and williams

F1 2011 : Updated cameras, updated chrome for mclaren. Updated helmet shaders

F1 2012 : Updated helmet shaders, fixing transparancy issue on the helmet glass material, fixing some 3D issue on the helmets. League physics added

F1 2013 : League physics added, some fixes and hopefully sort the engine left/right stereo not being balanced right


If there's something I missed, something you want to be sure it's fixed or added please tell me now

I would have thought all those cars were already in AC, quality varying according to modders of course.

Of course, that goes without saying. I'm specifically talking about direct ports from AC Evo code.

 

[Pekkahe]

Installed ACE, couldn't even launch the bloody game for like an hour, saw that it requires to be online to play solo (funny how they never talked about that before!), asked for a refund.

They can shove their DRM up where the sun doesn't shine.

I does not require online to play solo. It requires online to have access to some cars!

Could anyone help me to create a pbr paint ext_config for this paint?View attachment 1418357

any update on this?

hi, sorry, I tried and didn't get far, because the hood doesn't have a seperate material , it's not possible to recreate this skin exactly ... (the cameleon paint will also stick on the hood and roof, where you want to have different materials - and my skills don't extend to adding extra materials , only painting /changing existing ones)

Hi. Where do you find this setting please for shadow resolution. Many thanks.

Any tips for manually reducing file sizes for car skins? Most of the RD releases for the Porsche (both the LMh and the GTD) are in an absurd 8K format that no one in the world needs - especially me, who runs the game at a peasant's 1440p.

This of course means that individual skins can be hundreds of megabytes, which is ludicrous. I did a size analysis of my content folder and there are quite a few folders with crazy high file sizes - but skins I've sorted and added drivers to, which I want to keep.

And yes, I do use Compactor to compress my entire content folder. The fact I'm still scrounging for space should tell you what kind of absurd car/track numbers I have regardless.

Thanks to anyone who may know.

I tend to throw in this batch file in the skins root folder of the car mod , and it will go over all subdirs in that folder (so each skin folder) and compress the dds if possible... it saves quite some extra space (but you may wanna backup and compare and see if you wanna trade in the loss of fidelity for the extra saved disk space).

Yikes, the vr performance is horrible. I have a 4090 and a 13900k cpu, and it seems like its struggling. Weird texture issues, crashes. Looks like I'll be shelving this one for a while until kunos gets it sorted out.

EVO first impression for me indeed is bad...
my specs: 32gb ddr4 3600, Ryzen-9 5950x, 4080s 16GB, Windows 10 Pro, Quest3 via Oculus Link

 

[sDmD13]

does someone here maybe know if i am allowed to link my mod post from here on overtake for the additional skinpack?

and also many thanks for ur feedback everypne, that makes us very happy. but we need some help to fix some stuff, have a nice weekend🤍

I must add, to the understanding of strictly myself, and because you certainly didn't ask for it, that there is a way to overcome most of the VAO issues and get a little more control on them (such as VAO saturation) by exploiting a glitch in the Pure matrix.


You can set the light.distant_ambient.distance to 0.005 and then use the light.distant_ambient level to overlight the close to middle depth scenery, including the VAO. This works especially well on old tracks (or really basic conversions) that didn't get much attention and are showing insane amounts of contrast on isolated 2D objects, leaving the cars parts, cockpits and closer roads with its correct amount of ambient occlusion. The distant.light.saturation now acts as a sunlight saturation selector for the VAO(works only with ambient lightV1).

On ambient lightV1 as well, the light ambient.level is now strictly associated with your cockpit, another hack to highlight dark cockpits in some situations. It is a little more complicated with ambient light V2 but i'm pretty sure you had enough non-sense for the day😆.

Once scripted to fit your artistic preferences it is pretty beautiful.


I know that i've completely lost you (my lawyer is basically showing the same face as yours right now, begging me to plead for insanity on some unrelated case), but i couldn't keep this secret for myself any longer.

 

[Masscot]

@Peter Boese I keep hearing that I should switch from Pure Gamma to Pure LCS because it's objectively 'better', and more efficient, and more 'correct'. So I'd really like to switch.
Things look pretty good to me in Gamma with your PureVR PPF, but if I switch to LCS using the same PPF then grass goes very pale and other things just look subjectively 'weird'.
I guess what I'm asking is: shouldn't the current PureVR PPF (and other 'Pure' PPFs that come bundled with Pure?) be relabelled as PureGammaXX and a new set of PureLCSXX PPFs be included?
Because in my experience the generic 'Pure' PPFs might work with Gamma, but don't necessarily work as well with LCS.
I know I could tweak the config myself but I've no great understanding of the parameters and no real interest in learning. I'd much rather trust the expert (ie you) to come up with something appropriate, based on your extensive knowledge and experience.
People keep recommending various paymod PPFs from snake-oil salesmen and shysters, but in my experience, in VR, they're mostly garbage.

You bet! 😆

Jokes aside, I had a vague idea of how this VAO thing works, but thanks to your and Peter's explanations I now have a broader view. You learn something new every day!

Thank you all for taking the time to explain these things to us.

Actually in Pure LCS the normal "pure" ppfilter will manage Screen, HDR and VR automatically. So please try this first. You can manage your taste how it looks in the Pure PP app. In the Script tab you can adjust "photorealistic" and "soft look" to get the picture to your liking. Also you could try to use the "Natural mod" ppfilter which seems also great for VR.

update your nvidia drivers. It could also be a good thing to use the "Studio" drivers. But maybe first try the "Game ready" drivers.

I'm still hooked to gamma as well, but if you tell us all the things you wanna change we can either guide you to the proper slider or even make a few pp configs to try for (you would click import and try them in a click).

For my vintage cars and tracks it doesn't work great for example, but for modern cars and recent tracks it is pretty neat. What's a combo you're playing on atm?

 

[Gregz0r]

Does anyone know how to lower the visual(at least) ride heights of the ACFL 1994 F1 cars? They're decent grid fillers, but they all look like they've jacked up way too high on their suspensions.

In CM->select car->go to 'unpack data'->in the created data folder go to 'car' and then alter the second number (y) in GRAPHICS_OFFSET (the higher the number, the lower the car goes).

Then save file and in CM 'pack data' . You can check the height in showroom by clicking 'align using data' (you can save that too, for a correct preview showroom picture).

Thanks, but all I want is a PPF that looks like PureVR does with Gamma, but with LCS instead.
PureVR with Gamma works for everything. The very last thing I want is to have to chop and change PPFs depending on the car/track combo, the weather, the time of day etc.
Do some people really have to do that?

 

[JK1977]

How long before all of the AC Evo Early Access cars and tracks get ported to AC then? I bet some people are already on the case.

ill try a car and ....it works perfect (488 evo)

You got it wrong. I was trying to figure what cars/tracks you were mostly using, just to see how Pure LCS behave on them.

You might just be one slider away for it to be good looking, that's why i asked.

(the cameleon paint will also stick on the hood and roof, where you want to have different materials - and my skills don't extend to adding extra materials , only painting /changing existing ones)

thats fine, could you provide the ext_config you made? I might be able to fix it

Basey in suspension.ini but it change the actual ride height, so for an F1 might not be a good solution since the suspension travel isnt that much

 

[sab001]

That '62 corvette looks great! Where did you get it from?

Just took one of the existing C1s (the one with the most separated meshes) and stripped off the extra bits. For my scca stuff I have hacked up every car from the 50s & 60s to remove as much chrome as possible (or un-chrome it with csp), replace wheels with simpler steels, added roll cages, replaced seats, hide radios... but I haven't determined how to distribute this stuff. I have scca seasons with reasonably accurate grids, Marlboro 12hr, early TransAm (under/over 2L), Marathon de la Route (nurburgring) (love those Tatra 603s!), Bathurst...(etc.) I'll release Marlboro 12hrs first, probably with a list of cars to acquire with and an array of .kn5 updates to strip them down. (That way credit remains with the original creators...?) And although documentation linking car numbers to drivers (and to liveries) is quite sparse, a full set of skins will come with. Plug & Play 60s SCCA is the plan.

Great man, appreciate your work, about 2010, the rain tyres are making trouble as the sidewalls go chrome and the game crashes soon afterwards and the Renault could maybe need the F-Duct version (model), about 2013... The gear ratios need to be optimised in my opinion but apart from that there's nothing I can say against it, truly great work, 2007 maybe rain physics missing but when putting it close to 2007 mod it'll come I suggest, if not... Yeah then not

sidewalls go chrome? weird i messed up the naming? maybe

Renault F-Duct won't be done, would make sense if I had an actual fduct system in physics.

2013, gear ratio mmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm will see. was 2011 gear ratio good?

rain physics I already said can't be done, I have a steam deck, enabling rain on it is not possible so I can't test rain.

Ah, gotcha. Sorry, I misunderstood.
I don't think cars are the problem, it seems to be tracks.
Eg, Autodromo Brno, with Gamma and Pure VR PPF the grass looks as intended, but with LCS and PurePPF, the grass is far too light, a real pale green.

Could it be the new topography? I personally didn't like the look of the new topography, so I kept Brno v2.5.1... its grass looks perfectly fine with LCS and Pure PPF on my single monitor setup.

You may want to stick with what makes you happy. If it's Gamma, then keep using Gamma. In addition to CSP and track variables, there are PC and monitor hardware/software that we each have.

Automotodrom Brno v3.1
This release includes brand new 3D topography and tree planting based on satellite images and contour data.

No, the grass I'm talking about is the trackside/infield grass.
I'd happily stick with Gamma but hasn't @Peter Boese said himself that LCS is what we should be using, in the same way that we should be using Pure, not Sol?
Surely there's a way to use LCS and get whatever benefits it brings without having to make adjustments to track configs?
Surely there's a PPF that makes LCS look visually much closer to Gamma regarding tones, saturation, brightness etc?
That's why I'm curious that Peter hasn't included LCS-specific PPFs with the latest builds... because the ones created for Gamma look quite different with LCS. As you'd expect.

(edit: I somehow managed to miss Peter's message above before posting this)

Let's say... 2011 seems a bit short as well but somehow you'll not reach it but it reaches the limit at 310kph almost... seems short but is reeving up slower than 2013 so it get's better, but maybe would be good to take a look at it
