Rtx just isn't working

Below water, things are beautiful, but once I go above the water, everything is pitch black. Is this something on my end or is this a problem with the software, I'm really not sure. Pictures below are what things look like for me in a few of the worlds. I'm using a RTX 2060 GPU, and other people don't seem to have many problems when using this GPU, so I really don't know what's going on.
