Rtx works, everything else is black

Basically I have all of the required hardware to be able to run the new RTX beta. However, when I load into a world that has the RTX enabled, everything is black and the only thing visible are particles, white signs, and the rays. I am able to turn the RTX off and everything returns to the original Minecraft, and I am able to see. Also another bug that I have noticed as I am typing this Is that Iron bars severely lag my game, dropping its frames to about 23fps.
