While the game performance is still very much on the low side depending on the
area/scene I have discovered a way to boost overall performance for this game
on Wine:

1) Start the game in a new Xserver. This will give a 40-45% (ish) increase in
performance (most other games I don't see much noticeable difference).

2) Run the game with (if you have NVIDIA) __GL_THREADED_OPTIMIZATIONS. This
gives an additional boost in fps.

The final tally amounted to a 54% gain in a given scene over standard launch.
Just running with __GL_THREADED_OPTIMIZATIONS alone is enough to give the game
a bit of a performance boost, but surprisingly the new Xserver (not just a
non-compositing desktop) does the lion's share by itself.

I'm not sure what it is that causes it to make such a massive difference in
this one game.

(tested with NVIDIA Driver v310.14, and Wine 1.5.15)
