graphics card amd hd 6450.
that's what im using runs fine for me, obviously my graphics is low low end lol and performance is an issue to be honest, but if you got a mid/high end gpu you shouldn't have much problems with it I don't think, not to sure if there is a known specs minimum, im not sure if it runs on xp/vista or not as I use win 8.1, sorry m8 hope it helps
have fun stay safe
