If you own a PC with a dual core processor, do not buy this game. It was not optimized for dual core processors even though they were available at the time of its release. I can only run the game by disabling the sound which is a damaging blow to the overall enjoyment of this game. Lucasarts has only released one patch for Battlefront II, and that was over a year ago, which did not solve the dual core crash fix. Lucasarts have been absolutely useless in their attempts to resolve these problems and it seems they no longer care. Instead it's been left to the customers who bought this, to figure it out for themselves. This is a faulty product as far as I'm concerned, and really it should be taken off the market.
I'm not exactly sure how it will perform on other computers, but I've been through every forum relating to this topic, and a lot of people were having the same problem as me. There is no solution to this. If you buy this game, and find that it's not working properly, then it's your own fault.
