Hired it out the other day to try it out, since I'd played it on my laptop but wanted to try playing it on something that would run it a little better. The PS3 graphics looked like PC graphics set on lowest possible quality. There was MASSIVE anti-aliasing issues, shadow issues, huge load screens for every single cutscene, even in and out of your options screen would have a loading screen, and even after that loading textures would still have to load in, plus it couldn't even hold 30fps. If it were just the graphics not being the best, I could possibly overlook it, considering the game itself is great, but It felt like the game was lagging the entire time I was playing it. It seems to run fine, and look great on the newer gen consoles, but don't bother with it on older gen.
TL;DR PS3/360's can't handle it lowest possible graphics horrible anti-aliasing and shadows frequent and long loading screens can't hold 30fps, feels like it's always lagging
