The -march option may or may not invoke mmx, sse, sse2, etc in the CFLAGS line but it definitely does *NOT* invoke them in the USE variable. > USE="gtk gtk2 gnome -apm -eds -emboss -gstreamer -qt -qt3 -qt4 -kde > -ldap -arts -esd -oss -xv X a52 aac acpi alsa avahi bash-completion > bluetooth cdr cjk crypt dbus dvd dvdr exif firefox gphoto hal ipod > jpeg mbox mp3 nptl nptlonly ogg opengl png pulseaudio spell ssl > startup-notification svg theora tiff vorbis wifi xinerama" I have mmx, sse, sse2, and a few AMD-specific options in my USE variable. Can you show us the output of the command... grep flags /proc/cpuinfo Then we can see what to add. If you are *NOT* taking advantage of the available extensions, you won't get the available oomph out of your cpu. It's not so much a matter of raw speed as ability to do complex calculations in the chipset microcode, rather than painfully emulating it in software. One of the features of Gentoo is customizing your build to get the most out of your cpu. Use it... within reason. mplayer also takes a few custom flags. In /etc/portage/package.use I have the entry media-video/mplayer custom-cflags i8x0 real 3dnowext mmxext With an Intel cpu, you obviously don't want "3dnowext", but there may be other stuff worth using. To find out what's available, use... grep mplayer /usr/portage/profiles/use.local.desc | less -- Walter Dnes <[EMAIL PROTECTED]> I'm not repeating myself I'm an X Window user...
