Yeah, it’s pretty crazy. Look in the Render window and watch the Geometry Cache bloat to obscene levels as you render displacements. I don’t mean to criticize it I’m sure it’s using as much as it needs to but wow. I’ve only got 2 GB of RAM on my machine, so it can get a little scary sometimes, and on my girlfriend’s 1 GB MacBook you can forget it unless you go in and isolate the displacement to only the essential polygons (which can be a pain).
EI’s bump-maps really are fantastic. Unless you get super close they look almost as good as displacements. Obviously there’s things you can’t do that you need displacements for, but I was just appalled by modo’s bump-mapping. I don’t even bother trying them anymore they look so poor; I just automatically switch the channel to Displacement. And happily the displacement quality is great if you’ve got the RAM.
