I have 8GB of RAM, an AMD FX-8120 Black Edition (eight core), an Saphire R9 270X 2GB GDDR5 and windows 8.1, the problem is, i posses the minimum requirements needed to play the game and im not able to maintain 30 fps on LOW with everything turned off (V-sync, AA, etc.), and i am having constant dips in the frame-rate every 5 seconds approximately that just freeze the game for a second and then keeps going in a range of 16-25 fps varying constantly, i have all the patches installed, i don't know if its my computer or not, but i don't think i should be having that bad of a performance.
