CPU spike to 99% sometimes 100% when streaming

I have been trying to stream fortnite for the past couple months and everytime I stream I start stuttering and freezing up especially when in gun fights. My friend who has an i5 4590 and has the exact same gpu I have is able to stream fortnite without any stuttering totally smooth, no drops below 60 whatsoever. I thought it could be my drivers so I downloaded updated ones and not only did it not help it made it worse

My Specs:
CPU: i5-7600k
GPU: DUAL Asus gtx 1060 6gb
8gb ram
MOBO: GIGABYTE Z270X-ULTRA GAMING
Storage if that matters...
samsung 850 evo 250gb
BLACK WD 1tb

Change graphics settings on gpu....

cant tell if it helped still stuttering

gaming while streaming with a 4c/4t cpu equals high cpu usage and /or marginal streaming....

Fact of life

Use quicksync (QSV) or nvidia nvenc to stream,fortnite is just badly coded it has to be the program running with the highest priority to run smoothly but so does CPU encoding so you always get stutter with fortnite.
Only other thing you could do, if you don't want gpu encoding, is to use affinity and put two core towards the game and two towards the streaming and then fine tune FPS and streaming quality to get the most out of it.
