Ah, OK, thanks for explanation.

I tried this, however it didn't help. Eventually I recalled myself
about libtxc_dxtn. Installing libtxc_dxtn.so allowed Diablo III to
start! :)

I didn't have a chance to try gameplay yet, but will give it a chance later.

Actually installing libtxc_dxtn.so was enough, overriding OpenGL
version to 3.0 wasn't needed.
