Yes, Glest is very very wasteful of memory. That said;
Are you counting CPU or GPU memory? And how are you counting it?
This, If it is video memory i would be as the devil would say it in "the pick of destiny" shit out of luck.
Anyways, Yes can we please clarify wich memery we are talking abuot, also for clock speeds ect,ect.
Anywas, 1,5 gig isnt too bad, perhaps for what MG does its too much, but consider this if the md5 format is soon comming a computer wich have less than 1,5 Gigs of ram would not be able to play the game anyways because of its videocard.
(it sound a little vauge, but i think my point came across).
