it says it makes it possible for low end computers to play EB but, what about one old like mine?:

P4 at 2.0
nvidia 64 mb
384 RAM

i can play Vanilla with med or high unit detail, large size, unit shaders (without them some units have no feet) and everything else on lowest. I play DarthMod, RTR PE and TIC as well with the same "quality" but when i tried EB 1.1 i had 5 minutes turns and it was not bearable.

if it's gonna lag lots i don't mind waiting until i can buy a new computer.
