The megatextures are stored in an HD Photo-like format (something like a more advanced jpeg image compression codec) because it gave them the best possible compression, but the downside is that this means they cannot be used directly by the GPU.
So they have to be transcoded on the fly to a format the GPU can use. The PS3 has the edge on the 360 here because it uses some of its numerous cores to do that in the background, and on the PC if you have an nvidia graphics card it uses CUDA to do that super-fast.
