Ryabyat shadow grass (Red Dead Redemption 2)

This question... No TAA smoothing very hard ryabyat shadow grass. At any resolution, with any scaling with FXAA and MSAAx8 this ripple is visible. Tried to put shadows on ultra and on minimum payout, were cut on an ultra cut down and even soft shadows, I turn on SSAO... all to no avail!! not the normal quality of these shadows is not done, not to knock the fuck can't.
Moreover, the most interesting is that grass is a normal clear of the shadows that flicker is not so, and here is how to izbavitsya from soft shadow is a mystery.
Maybe someone knows which slider to pull to make them either really soft or cut down completely.
