I can suggest a few things that may help, but yes, your CPU is an issue with
this game. Updating it would help the most helpful actually, although I suspect
even with a overclocked SB/IB it will still be too slow to be at a nice frame
rate.

1) Set UseGLSL = disabled in Direct3D in the registry. I get around 10%
performance increase with this set. It's not officially supported, though, and
causes issues in some games.

2) Gcc's profile guided optimisation. May help, may not. I've gotten 5%
increases from using it in the past. Doesn't work for wine as a whole, you have
to do it for wined3d only.

3) Overclocking your CPU, and maybe GPU as you might be bottlenecked there as
well.
