Assetto Corsa PC Mods General DiscussionPC

[Peter Boese]

hi , can someone explain these 3 values please? (Why don't these things come with a tooltip explanation??

Unfortunately the last digit does not increase the range (distance from the car) until where shadows are rendered in details

these are my settings:
View attachment 1390845
I can clearly see that the shadows become less detailed approx 20m in front of my car... )
View attachment 1390846

increasing the last number to 2000 as Masscot suggested,
still the detailed render distance seems same, but after that the shadows are no longer rendered at all ... so it got worse instead of improved:

View attachment 1390872



EDIT: in fact LOWERING this number seems to have the desired effect!

View attachment 1390873
View attachment 1390874

EDIT2 : and yet the same settings don't seem to fix it on all tracks! For example on Charlotte Motor Speedway Oval , I still get blurry shadows after some distance:
View attachment 1390886

EDIT3:
it seemed to me the best solution is to disable Smart Shadows altogether... but then I am faced again with this disturbing shadow issue of the shadows only being drawn in front, and when looking to the side, you can see the shadows are not drawn there :
View attachment 1390892

So please WHAT are good settings for having realistic shadows (that don't cut off anywhere too obvious) ?

You can't have superp settings for all situations with these 3 values!!!

Those are the distances of the shadow cascades.

So in AC the shadows, or better the shadows resolution, or better the resulution of the sun light processing on track objects is splitted into 3 or 4 parts. Also the resolution within such a cascade is dynamic, dependend on the range from one to another cascade.

So the first one (the nearest one) has the biggest resolution. It is the resulotion you set for the shadows in the AC video settings.

So the higher a value is there, the more distant the next shadow cascade is, but you will also lower resolution if you widen the cascade distance.

So the quality of shadows in AC is always balanced to reduce the load on the GPU.

You can set it very high quality, but only with the cost of being very rough in the distance or vise versa.

The only way to have overall superb quality is to set the 3rd value very big and set shadows resolution to the highest possible.


And you have many many optimization methods in AC to bypass the shadows rendering, because it is always heavy. So you might see sudden unshadowed things out of a certain FOV.


So sunlight light processing is the most GPU heavy render thing and thats why there are so many methods to minimize the load.
Because noone will understand it, that for good shadows your fps will massively go down.

Here are settings for very good shadows:

But with a very high GPU load!

Hi Guys

This car was recommended to me a few years back by @Fanapryde , still one of my favorite cars to race around.

In my opinion this is the best mod in it's class including all street variants and other mods, just feels and sounds awesome!

Interior needed some updates so have added my touch a bit

Installation:

- You need to have the eatc_bmw_220i car mod installed first

- Car download link in my download

- Copy textures in Interior_update folder into each skins folder


Update details v1.2:

Whilst updating a track have been using this car, although I did update this car already, decided to step it up a bit as per my other interior update mods. This is a complete rework of the interior with new textures.

BMW 220i Complete Interior texture update

Hi Guys This car was recommended to me a few years back by @Fanapryde , still one of my favorite cars to race around. In my opinion this is the best mod in it's class including all street variants and other mods, just feels and sounds awesome...

www.overtake.gg

This is indeed a lovely-to-drive little bolide.
And your texture update is a significant visual upgrade.
Double thanks are due!


For everyone... Just curious. This is/was a fictional championship, right? The EurAsian Touring Car Championship?
Neither web search, nor AI research returns anything useful. Except that our mate @Toonces created a slew of setups for different tracks. Seems like the 220i was a baseline model, never was an M220i, nor a GT4?
Car certainly drives like a M GT4 ito authority, agree with @Toonces, perhaps a smidge TOO grippy.

Great fun whatever the truth.

Yes, these are close to the settings I settled on and posted earlier. I run 4096X and don't see that much load or much less quality than 8192. Maybe due to my 3rd split being much closer @ 250m.

Hi All, I don't seem to be able to find the answer to this online. I have follow Kunos car's brake disc shader setting for the brake disc for my mod, but I do not get why even when the car is stationary, the brake discs were blurred as shown below:

Shader Settings:

and I have only added the burred texture to the txBlur slot. Anyone can kindly explain why? Thanks!

The real load comes with low sunangles.
You can compare the load with CSP render stats app and you can switch shadow resolutions ingame with the video mode app. There you see the bigger load. Its a direct and linear load progression. There is no magic behind it. If you have shadows at 4096x4096 it will use 4x the load like 2048x2048.

Also you always need to check for the pop-in/pop-out shadows. Like at tracks with hills, set a low sunangle and drive around the track. Only with a high 3rd value you will prevent those shadows fluctuations.

I don't have that problem, but you can change this in Smart Shadows. Search for "Look Direction" in Custom Shadow Matrices.
If you play in VR like me this should be set to "Don't use in VR".

Strange that a simple mesh adjustment destroyed the windshield wiper. But it is possible that there is really something wrong with the csp: on the z3 I had to create two separate models because I could not insert the gtr rims (every shadows disappeared). Maybe some scripts stopped working. Consider that the wiper was coded almost at the beginning.. time will tell. 🧐

in the skin ext_config, if I replace number of "[MESH_ADJUSTMENT_X] (X is number 0/1/2/3) by [MESH_ADJUSTMENT_...]" wiper is working.

other issue, I have very low power of braking, I tried with and without extended physics without succes.

EDIT : I think it's because you haven't anything about ABS on the electronics.ini file
IF you add this below it's Ok (maybe settings aren't accurate) :

[ABS]
SLIP_RATIO_LIMIT=0.17
CURVE=
PRESENT=0
ACTIVE=0
RATE_HZ=58

Just had a pop-up in CM, Data Update 185. What does this mean? Is it CM? Custom Shaders Patch? or something else?

[alexfre]

Hey everyone, I recently updated CSP and went to race at Mike08's Lienz track and got a crash: "Failed to allocate GPU memory" - after doing some research it looks like an update in CSP changed the way camera_facing.ini loads and causes this crash. So far this is the only circuit to have this problem.

Any ideas on how I can fix this issue so I can run this track?

same problem in some circuits, csp 0.2.5P1 .
I have not found any solution for now.

With your suggested settings I no longer see the cascade split anywhere even with late day long shadows. I'm using 4096 shadows and it looks great. Thanks!

edit: I found a few places where the split is still evident but it's *closer to me in cockpit view but seems less imposing (perhaps depending on how far I'm looking ahead?)

GT1 class does not have abs or tcs. I think ChemFlummi did not include them for this reason

I'll take into account what was said about the mesh adjustment, at least this way I won't have to redo the windshield wipers from scratch again LOL


Now a little question: since I switched to pure LCS and the new CSP I have all these graphic artifacts (lights and reflections with every PP-Filter I have). Does anyone know what causes them?

Not a fizix expert, but I don't believe the electronic.ini should ever be left blank, no matter how opinionated the modder/driver is about <clarkson-anorak-voice>XYZ CAR DID NOT HAVE ABS!!</clarkson-anorak-voice>.

There are driving modes which activate ABS by default. If the electronics.ini is deliberately left blank, at game time the AC engine could be left in an indeterminate state, because the entries required to process ABS simply aren't there. Symptoms are typically a 0.5s period oscillation of the steering (particularly on older non-DD wheels) and a non-responsive brake pedal. This can be fixed at the setup screen by manually turning ABS off (every.time.you.drive.the.car) Ask me how I know

If the electronics is populated, the values will be used, and PRESENT and ACTIVE parameters will be respected. If these are both set to zero (=0) the ABS will automagically be turned off correctly, no matter what the driving mode is set to. Ditto for TRACTION CONTROL/EDL.

I have yet to experiment with culling the other parameters in the file if PRESENT and ACTIVE set to 0, to see if anything catches fire. Soon

[ClimaxF1]

this is all good and well , but the brakelights are no longer distinguishable when lights are on (without having to resort to turning PP Effects on), so it's no fav+ in my book...

Not sure what is causing the problem on your side but definetely don't have this problem

Are you not supposed to have PP effects on, could be wrong but not sure why you have it off

Been having this "problem" for a while now, might not be the only one...
SkidmarkFX, before the skidmarks would stay for days, giving character to tracks. Now they disapear every time I restart my PC??

I preffer PP off , for VR performance reasons (I'm running Oculus pixels per display 1.8 , high resolution, and then PP introduces application framedrops)

There are examples of cars that have visible brakelights without having to use PP (Glare), so it is doable!

For example the Dodge Viper (SR I) RT/10 - 1992 by Alberto Daniel Russo; Real Specs (rs_viper_rt10_92) , for which I created/updated some chameleon skins today :
