These are speculative requirements based on Gears of War for PC, which also uses Unreal Engine 3. Bulletstorm is using the latest Unreal Engine and has been reported to support DX 9 and 10, so the final requirements are expected to be higher.

最后这句说明是猜测的
"以上是个人电脑的战争机器，它也使用虚幻引擎3的投机性需求。 Bulletstorm是采用最新的虚幻引擎，并已上报支持DX9和10，因此最终需求预计会更高。
