suspose i should have been abit more clear.
LFS is only able use one core, as i am sure you know. Now, the xbox's processor is 3ghz, and the ps3's is about the same, yet granted a little higher. The xbox's processor is a 3-core system, and the Ps3's is a 8-core system. Now, divide 3ghz into 8 cores, and get the total of ONE core. Then you will see why i said it wont run. As said before, the ps3 will handle the graphics part of LFS no problemo. As for the processing part, its a no-go im afraid!
