Austin, could you please retest with 1.7.8 ? I don't have this issue. Nvidia driver 331.20
As Stefan said in comment #11, you may be hitting the Nvidia caching.
I'll test whenever I can get gentoo to build non-broken wine. If you can test again, try: $ mv ~/.nv ~/.nv.bak $ ln -s /dev/null /.nv
then try the game again
