Forgot to mention this earlier but the game appears to use something akin to id Software's megatextures for the Titan textures. Many of them are huge, non-repeated images stretched across the Titans' bodies. They're also used for distant LOD, so many times, the vistas that you're looking at are nothing but one big texture.
Kinda reminds me of pre-rendered backgrounds!
