Looks like Bugzilla swallowed my earlier post.

No, it's not even close. For this game you're clearly better off by disabling
dynamic VBOs, e.g. by commenting out the extension in the extension table at
the top of dlls/wined3d/directx.c

The (presumed) proper solution is a worker thread that executes all the
commands. That way we can do the ordering sychronisation ourselves with classic
thread synchronization techniques rather than forcing opengl to do it for us by
calling glFlush() after pretty much every operation. This is a complicated task
and won't happen tomorrow however.

I don't intend to work on any hacks that attempt to improve this game's
performance in the current way multithreading is handled.

Yes, there was a bug that was fixed by
