Eric, here is the page I told you about. It also has instructions for setting Java memory allocation in a youtube farther down the page on the "thread" link.
LB Photo Realism 64x pack with bump maps
The bump maps look good even on 64x. Totally ridiculous on 128 or 256, but I doubt I can run it without stuttering bad.
The only thing I'm not in love with is the speed of the animations. THey're all running way too fast. Dunno if that's my rig, or a settings issue. Will look into it.
