2nd on butter, Yikes! 6-8? I would guess,, yes! Very normal. 150+megs each x 8 and you're getting close to your Ram. You can hide a few at a time. Should speed things up. Use low res textures. You really cannot see a 4000x texture with an 8 figure scene, anyway. Make sure you are on Scree3D, too. Avoid any full preview with this much weight too. Use Doc style.
