Strange, on Debian Stretch, Nvidia propertiary drivers, and wine-stagging I haven't needed to install any tweaks or directx things - first Mount&Blade just worked perfectly fine (and exactly the same as with d3dx9_36, or any other, installed - I've checked just out of curiosity).
I'm also unable to use first person view (screen just freezes, and unfreezes when i toggle back to 3th view) in vanilla - surprisingly, it works in Conquest mod.
...and guess what, first person view started working in vanilla first M$B out of blue sky. go figure.
