Curious how the two Orange Box versions stack up? GameVideos have put the PS3 and Xbox 360 next to each other side-by-side - literally, it's a pretty impressive split-screen effort - of Portal and Half-Life 2. In fact, the visuals look very similar.
The major difference, where one might consider the PS3 version "downright unplayable," is the load times. For video HL2, the loading difference shown is not as great, but Portal's comparative load time shown is rather drastic. See for yourself after the break.
