hi, i recently bought a gigabyte gtx 1080 xtreme gaming to replace my gtx 960. i used to get around 200 fps with the 960 but i only get 120-150 fps on the 1080, the card is used 30% and my i5 4690k is used 70-80%. my rig is a i5-4690k, asus b85m-g, 12gb 1600mhz ram, 1tb hard drive and a 250gb ssd from samsung. why is my framerate so low and how can i get a higher framrate.
