No, sorry.If you realy want to, you need to invest some money.
This is what they recommend, but I think they should call this the minimum requirements:
CPU: 2.66 GHz Intel Core i5 or 2.6 GHz AMD Phenom II X4 recommended
RAM: 4 GB
OS: Windows 7 / Vista SP2 / Windows XP SP3
Video Card: 1 GB DirectX 10 compliant video card (NVIDIA Geforce 8800 / 9000 / 250 / 460 series or better / ATI Radeon HD 4850 / 5000 / 6000 series or better)
Sound Card: Yes
Free Disk Space: 10 GB
Playing this game not at higher settings is just a waste.
