Small dots and blurry shadows

I have a GTX 1650 and I have some issues with the shadows. I see many and many little points that make the flight simulator look quite bad. It happens mostly with clouds and shadows. I have attatched an image below. I’m very new to flightsim and I have almost 0 knowladge of pc stuff. You can see in this picture that clouds look strange.

Thank you very much for your attention.
Best regards,

Here is another picture, you can see the Sr22 panel looks strange.
Thank you very much in advance.
