The Temple ruins.
The trick to that prop set is replacing the materials. The original material settings mean that each and every part of the temple has its own hires texture, and since we're talking a lot of props here the texture memory adds up.
Replace all those texture maps by a procedural shader, and your memory woes are over.
Works for my system anyway.
