It's not that because a game is coming out on three platforms - the PS3, Xbox 360, and the PC in this case - a game would be compromised to the lowest common denominator, or that the other versions can't keep up. Rather, as Mark Rein tells GamePro, Epic Games is committed to making sure that each of the versions of Unreal Tournament 3 is optimized for each platform it will appear on.

So it doesn't matter if a PC can hold 2GB of RAM and the PS3 and Xbox 360 has only a smaller amount of memory to play with. Rather, each platform presents its own challenges:

The big difference is you have 'one.' There's one kind of machine for PS3, there's one kind of machine for Xbox 360. So whatever power there is, you can completely exploit it, and you can customize it for that particular CPU, that particular graphics chip, and that particular bandwidth. So you can dig very deeply into the hardware. Whereas on the PC, you wrote a game that was perfectly 100% optimized only for Nvidia, and only for dual-core, you wouldn't sell very many copies of that game. Invariably, you have to have a game that can scale a across a large range of hardware.
