Wow, you aren't kidding...
I made a silly little object, applied Loop subdivision a few times and got an object with about 35K polys (almost tiny, in CGI terms). Had to kill most of the other apps on the machine to avoid thrashing. Saved it as a .obj file.
Now I'm trying to load that file on my rather slower home machine (ok, a lot slower... 450Mhz P3), and I've been waiting for 25 minutes so far, just for it to load. I know my computer sucks, but this is ridiculous (even blender is kinda sorta usable on this machine)...
