Missing sun shadows with RTX

Hi all. Such a problem, in the settings for the quality of shadows from the sun there are only items:
-Very low
-Low -Medium
-High
-Ultra Previously,
there
was also PCF, which gives PTX shadows. But this setting does not exist. The render mode is D3D12 Ultimate (Ray Tracing). All on ultra. Need your advice. And yet, I understand that there are no RTX reflections in the game? For the quality of the reflections is also on ultra, but it is clear that they are ordinary. At the edges of the screen, reflections disappear on the water. I didn't find any information on the net. And in general, opposite the settings, "Ray tracing" was also written earlier.
