Im getting 30-50% usage in my GPU and my CPU is completely maxed out in 4 cores

So I've gotten my new 144hz monitor lately and I've been playing in fortnite. My fps is around 120-160, sometimes it will stutter really hard to the point its unplayable. I usually play on 1152x1080 as my res. I cap my fps at 180 My CPU usage is around 80-100% And my GPU usage is around 20-40% My RIG I5-4460 4C/4T Asus B85M-G Mobo GTX 1050 TI 4G Some random Kingston 8GB DDR3 1600MHZ ram (single channel memory) Thermaltake Litepower 550W Acer KG214QP 144hz Is there any bottleneck and is there any reason to fix the CPU & GPU usage?
