Why are my shadows so jagged???

[tripecac]

Whenever I play ETS2, the shadows seem really jagged, or "sawtooth", particularly under guardrails. The shadows inside the cab also have a sawtooth edge to them. It is very, very distracting.

When I watch other people's videos on YouTube, I don't see those really jagged shadows. Their shadows seem fine. So why am I getting them, I wonder.

In the graphical options I have shadows cranked all the way up. I've tried 400% scaling with full in-game AA, and also the roextended NPI route (100% scaling with no in-game AA). The jagged shadows are still there. So's the flickering on fences, foliage, etc. NPI miight help a little, but I'm nowhere close to what I'm seeing in videos on YouTube.

Is anyone else experiencing jagged shadows?

What are some things I can try to get rid of the jaggies (and flickering too hopefully)?

Thanks!

Known issue with the current AA in the game.

If it's a known, unavoidable issues, then why would so many of the ETS2 videos on YouTube seem like they have smooth shadows?

Would a graphics (skybox) mod change the way shadows appear? Most of the YouTubers I saw are using graphics mods.

YouTube does a ton of compression meaning that you will lose a ton of detail including AA issues.

My shadows are (pretty) smooth. Maybe you could post a screenshot?

A screenshot of how they looks on your side may help. Check into your config.cfg file for shadow related entries, if values there are matching your settings. > Documents/ETS2.

Ok, here's a screen grab showing my jagged shadows:

https://tripalot.com/issues/img/2023-06-27-ets2-jagged-shadows.jpg

My in-game shadow settings are maxed out (Ultra and High). Here are my shadow-related settings in config.cfg:

uset r_cloud_shadows "1"
uset r_fake_shadows "2"
uset r_sun_shadow_texture_size "4096"
uset r_sun_shadow_quality "4"

Another thing I notice is that as I inch forward, the shadows jump back and forth. While I was getting into position to take this screen shot, there was a light post casting a shadow on a nearby wall; as I inched forward, the light post's shadow kept jumping left and right, which was very distracting. It's as if there's a rounding issue in the shadow angle calculation.

[kaki_gamet]

Impressive ^^' I get the same with quality at "1" Are you using some third party software that is forcing in-game graphics to different settings? In this case try to disable it for ETS2.

what GPU do you use?

[tripecac]

I tried setting the shadow texture size to 8192 but still got jagged edges.

I noticed that if I go into camera mode, and move the camera around, the shadows look much better. It's only when I'm in the cab that I have those big "saw teeth".

My GPU is a 3080 Ti. I'm not using any third party software that I know of. However, whenever I start up ETS2 it mentions something about an SDK. That might have something to do with opting into the VR beta at some point. Does everyone get that message?

[kaki_gamet]

Nope. Never seen it on my side, but saw few reports in a distant past, maybe a plugin?

If you want, copy the whole content of your game.log.txt file (it is into Documents/ETS2 folder) on pastebin.com then leave here its URL. It may contain some hints if there is something altering the game (from its inside at least) : / Or give it a look yourself.

Do you perhaps have an AMD card?

I have seen many solutions for anti-aliasing issues (some are really complicated configuration). But the issue is in the game itself, I don't believe it can be solved for good.

And I agree with each side, sometimes its smooth but also jagged at times in my game. But I find out that the higher graphics setting I have, the less noticeable the issue.

Maxing out Euro Truck Simulator shouldn't be an issue for Samsung Fridges nowdays; i already had to put 400% res scaling because of (feelingly) no existent AA or LoDs; flickering still exists but its less distracting; now those shadows DUUUUUDE its annyoing af and theres seemingly nothing we can do about it besides editing the shadow res inside the cfg

[Rivaldman]

That's the best we can do (with the given game settings).

To get rid of the flickering, you can try the latest AA mod.
