Eh, i don't know...
It's Ubisoft, so there's an almost sure probability it'll feature Nvidia Physx.
You've got an Nvidia, and a relatively weak one at that too, but it shouldn't be that bad.
I'd say low at 720p will run and also be playable, but don't expect 60 FPS, nor expect the game to be stable (big, open areas will probably dip under the 20-30 FPS, but inner, less detailed spaces might get up to 40-45 FPS)
