ProMods

It is happening everywhere but I have tried to enable yellow road lines mod and than everything was okay. But you know I don´t like those yellow lines in Europe.

Since You say this only happens with ProMods, I am wondering when You generated ProMods def file, did You select High/Ultra draw distance, or did You leave it on Standard? I suspect with standard draw distance, You might get that effect.

That setting is only for Vegetation drawing distance, so it shouldn't affect this.
Must be a ingame Graphics Setting then.

In game is everything set on ultra and def file is with ultra draw distance so.
