If you are using SLI/Crossfire or the "dual gpu cards", (cards really use SLI/Crossfire, of course they leave that part out) you can set the game to use only one CPU core through your SLI/Crossfire settings (CPU is not a typo). I really hope this game uses multi-threading, especially with all of the ships/ai/planets/meshes it has to process
Or you can just set affinity with ctrl-alt-del. But I trust the game not to overstep its boundaries, if it does I'll reign it back in

Sorry I think I must have miss spoken what I was trying to convay. Thay can't clam that this is a game for both low end computers and higher end computers unless the dual core's and quad core's can use the game.
No, this still makes no sense. If there's nothing to use it doesn't matter, it'll just run like a regular single-core application (are you under the assumption non-smp aware games won't run on dual or quad-core processors?). You want them to add a bunch of inverse square root function calls or something to run on the other cores just for shits and giggles?
