after constant CTD's i tried to narrow it down a bit.
sadly i can't play longer then 30 min. or so, so i can't test much.
i deactivated sound, most FX stuff and turned on debug view, i hope the output helps a bit.
looks like some kind of DXerror to me:
ERROR: (CD3D9Renderer) Failed to create a vertex buffer (invalid call): size: 0 flags: 0 usage: 0.
and
ERROR: (CD3D9Renderer) Failed to create an index buffer

contains auto save (useless for me, as i always crash on loading), dxdiag and debugview of the game.
the crash dump:

ps i have ~30 other crash reports there, but they very mixed, some are with different settings, some are just from loading, if you want them you can find them here:
