[Wine] Fallout New Vegas Crash

[phatcanada]

Howdy all, I'm hoping somebody can give me a hand working out what's going wrong with Fallout. I've got the steam digital copy working through wine 1.3.21. I had it working a few months ago then got tired of it, and now I'd like to get back into it.

It installed fine, and I can configure everything and start playing the game. I can get through creating my character and move around in the first house, but as soon as I leave the game crashes.

I'm running Ubuntu 10.04 with an nVidia 8600gt card. Another bit of information, every time I run the game from steam, it does the Microsoft VC Redist Package first time installation thing, not sure if that's important.
