I have an AMD Dual Core system and I'm having trouble running BioShock
Some older machines that have AMD dual core processors may experience problems running the game. If you have such a system, you should first visit the AMD website and obtain the latest processor drivers. You can also install an AMD provided driver which addresses a timing issue from the BioShock DVD. You should only install this driver if you are confident that it is appropriate for your system (i.e. you have an AMD dual core processor).
