Best compile flags for VC 2005

[Anonymous]

Hi all,
I would like to know from you experts what are the compile flags you use with Visual C++ 2005, for maximum speed. I've got a nice 15% speedup over the GCC 3.4.x, but I'm sure it is possible to get a bit more, because the only flags I'm using with VC are: /O2 and /G7
Thanks in advance

By far, the biggest boost is from profile guided optimization.

Give the program a good hour playing.
