Well, your GPU at least, is well below spec. The GeForce 9600 GT listed as the minimum requirement is almost four times as fast as your GeForce 310 in terms of raw computing power (sligtly lower GPU clock speed, significantly lower memory clock and 16 computation cores compared to 64 on the GF9600).
Not saying the game won't flat out work, the 310 actually has almost the same technology support as the GF9600 (DX10, OGL3.3), but it might require heavy tweaking, especially if your CPU is near or below the recommended minimum as well. The problem is, as others have stated, there aren't really that many options to tweak currently.
