Since GNOME3 a DE will force you to have 3D acceleration, since GDM3 you
even need to install pulseaudio just to use this login manager, even if
you don't use GNOME, since GNOME3 [snip]. I read that if you've got a
graphics that has no driver (e.g. Nvidia graphics that aren't ok with
nouveau and most seems not to be able to run when this driver is used,
while using a kernel-rt that doesn't allow to use the proprietary driver
regarding to the GPL) then current GNOME3 will emulate the needed stuff
by using SSE2 for the math. You might run top and then run an app that
is using SSE2 math, e.g. JAMin, to see how resource hungry it is. Btw. a
C(++) compile isn't able to use special commands like SSE stuff optimal,
to do that you need to program in Assembler, since a compile has no
knowledge about the context of the (sub-)routs.
