even an aged and underpowerd nvidia chipset
will outrun intel chipset graphics.

i don't think that there is much you can do.

i have intel graphics in my laptop(s) and nvidia
on my desktop. i start vmd on my laptop only
occasionally to reconfirm how crappy the chips
and the (linux) drivers (still) are.

these days it seems that all that matters is to
have the composite extension work ok and
sufficient graphics to browse the web (which
has no popular site requiring full and fast opengl
support in any case).
