especially on ds9 there is big black holes in the airlock hallways and walls in quarks,looks like some ferengi stole the floor plates to trade for scrap

The TOS Connie interior is even worse. Every other wall is a black rectangle.

I think the game it self only use's DX 9 it does not fully support the DX 11 and i dont see the need for dx 11 there is not that much of a change.Just turn off DX 11 while playing sto.And if any thing DX 11 will make game look even worse.
