    Hi all, I'd like to know if it would supose some optimization to use /OPT:WIN98 setting in Visual Studio 2005 / 2008 with XP / Vista as target operating system. Thanks.

      Very less people run Windows 98, so give them a separate build with /OPT:WIN98 linker option. Otherwise, always build with /OPT:NOWIN98.

        Yes I agree, but my question was, if still would be useful to make code 4K aligned? It makes some improvement to run aligned code in XP or Vista? or depends on fat32 / NTFS? Thanks for replying.

          You just lose a few bytes in your executable size, that's it.

            so, there's NO benefit in run time execution?

              I played with this linker option some time ago, I couldn't see any difference in performance. This may be different for your code, just try it.
