I exceed system requirements, I have an AMD built PC. AMD A6-6400k Processor (3.9-4.2ghz). Also a ZOTAC nvidia geforce GT 630 graphics card (4gb dedicated ram) and 8 gb ram. the game runs smoothly and my graphics are set to low just to keep the game at optimum preformance. Also running DirectX 11. all drivers are up to date.
I also just bought the game today (1/16/15) so im sure all the patches are up to date.
