High fps but game feels laggy/ slow

I play Fortnite at 100+ fps and I can clearly see it's not being displayed smoothly (such as a 60 fps video).
My Specs:
GPU - R9 380 4GB OC
CPU - FX-4350
MOBO - MSI 970 Gaming
RAM - DDR3 2x4GB RAM

I don't understand why this happens. When I'm on the edge of the map, it looks fine but then when I go to the center of the map, the "lag" begins. FPS is still above 100.

I've checked to see if it was the monitor, but it clearly isn't as I have swapped with my brother to see if there were any changes. My brother's fps is completely fine and it looks really smooth.
His Specs:
GPU - GTX 750 ti
CPU - i3 - 6100?? 6th Gen that's all I know
MOBO - b150 bazooka
RAM - DDR4 1x4GB RAM

I'm am seriously puzzled as to what the possible cause could be. I've tried overclocked both CPU and GPU and I still get the same results.

Hope to have someone answer this! Thanks!

Are you running it only Windows 7 or Windows 10?

Try changing v-sync settings
I'm pretty sure it is caused by the cpu frame time. I would recommend downloading MSI Afterburner, you can display both fps and and frametime with it (including some other convenient stuff such as cpu/gpu temperature and usage).

Frame time is the time a frame takes to be rendered and displayed. And you want a consistent frame time for really smooth gameplay. That means that for 60 FPS you would want 60 clean frames being displayed in a consistent manner, that means a frame time of 16,7 ms (a new frame being displayed every 16,7 ms).

A possible way to solve this is capping FPS to 60 (by enabling V-sync or Free-sync in game options)
Or using riva tunner which comes with MSI afterburner and cap FPS to 60. Or get a better CPU since the i3 is much more powerfull especially in single core performance.
