Flickering and jagged edges on fences and shadows far away

I have a weird flickering and jagged edges on fences and shadows far away. Everything close looks fine ...but far away looks bad. I tried reinstalling drivers and the game, even reset windows, change framerate, ...still the same graphics.
I have a Ryzen 5 5600g, 32gb of Ram and Nvidia RTX 3060 with a Samsung G5 34" utrawide monitor.

Someone knows a solution for this ?

 

Turn anisotropic filtering down to 2 in game and set it to 16x in the nvidia control panel.

Using shadow detail on ultra also helps if you can take the performance hit. You can also use super sampling in game, but again its a big performance hit.

 

already tried shadows on ultra ...turned them off now because it was ugly,
Hdr is turned off

 

in the right upper corner , the fence of the pitstop and the end of the pitstop
quality of the video is not great but you can still see the problem

 

If vehicle and track reflections both need to be the same, why are there separate sliders? Also would you say that reflections on medium in 1.6 are about the same quality/a bit less, than as high in 1.5?

 

doesn't work ...still the same. post proc aa makes it worse

 

I turned on DLDSR x1.75 and x2.25, MFAA and FXAA in the Nvidia Control panel. Took a higher resolution in automobilista 2, with MSAA on high in the game.
It's still there but less visible. Also disabled bloom and lowered Exposure compensation to 0.7 in visual fx.
