no exact specs sheet has been put out but Ive been able to get it to run on a intel m7-6y75 with irrigated GPU and 16 gigs of 1866 MHz ram at 1080p
in open areas the fps drops to 15 ish but in closed spaces it jumps to 30 to 40 its playable but i recommend a better system personally run a i5-3450 8 gigs of 1600 MHz ram and a amd radeon r7 350x with oc when i need more kick
hope this helps
