d3dx function calls stats

It looks like the game calls the various matrix transformation functions A LOT.
In particular the final part of the log is mostly about the top 6 functions,
with a D3DXLoadSurfaceFromFileA("media/ff2.bmp") every now and then.

My guess is that a SSE implementation of D3DXMatrixMultiply and maybe the other
most called functions might help.
BTW, which version of d3dx9_xx.dll does the game use? You could check that by
looking into a +loaddll trace, for example.
