openmw.org

So I installed 64-bit Windows version of OpenMW, pointed it to the game folder, imported morrowind.ini settings and set the (probably correct?) load order (Tribunal first, Bloodmoon second).

Erm, can someone explain this?

I can reproduce this, and show my system specs if needed.

This looks as though your copy of libopenscenegraph does not have its dds loader installed, or that is not working for some reason.

I should ask different question then.
How to fix this?

K, I fixed the problem. Solution was simple - I updated my GPU drivers. Silly me
