can anybody tell me what part of a computer i would have to max out to speed up regens? is it mostly video? ram? processsor? i know all of the above would be optimal, but even with a p4 2.0, 768gb ddr, and a 32mb vid card, i have a substantial lag when i go from model to layout (or layout to layout) and i feel i should be able to flip through these instantly. the file is about 3 megs, but this is common for my type of work. any thoughts would be appreciated sean [email][/email]
