Game runs above 60 FPS, but doesn't look smooth.

New to the game, looking online hasn't brought up any relevant answers. Basically i can run this game above 60 fps but the image on the screen looks like its running at 30fps. VSync is turned off, game running at almost max settings 1080p.

i5 4690k @3.8GHz GTX 960 4GB 8GB DDR3 1600mhz 1TB HDD 7200rpm.

Game is being played on a 4KTV if that helps (TV supports 60fps) Thanks for any help.
