no change with that patch - I don't think it's related as nfsw.exe never calls
the function which is patched (GetProcessAffinityMask).

but as you mentioned it, I've also tested setting the process's affinity mask
to run on 1 cpu by using the following:

cat > affin.c
#include <windows.h>
int main(int argc, char *argv[])
{
 if(argc == 1)
   return 1;
 SetProcessAffinityMask( GetCurrentProcess(), 1 );
 ShellExecute( NULL, NULL, argv[1], NULL, NULL, SW_SHOWNORMAL );
 return 0;
}

then:
i586-mingw32msvc-gcc affin.c -o affin
wine affin.exe nfsw.exe

but there was no improvement.  the only thing which works is setting the
affinity of the wine process using schedtool.

As Alexander suggests it might be related to bug 4487 which says that wine's
ddraw isn't threadsafe.  If others agree, I think this can be marked as a
duplicate of 4487.
