That worked! It got rid of the crosses and weird textures.
The confusing thing that happened is after I removed -usetexenvcombine and tried again I can now access the game with all the high quality stuff with no issues. Thanks again everyone.
So here are some pictures of what I'm seeing. It doesn't matter what server or what settings I have on or what level I see these weird flickering crosses everywhere.
My Graphics card is a Radeon RX Vega.
Could anyone help me?
