I have had this problem since i got my new CPU. my old CPU an I7 960 quad-core @ 3.2Ghz ran these games better. It says in performance that my CPU is running @ 4.57 GHz but I haven't changed the clock speed in the BIOS. PUBG and all other games even though are running the CPU 50% don't stutter, but Fortnite is unplayable the amount it stutters. I have tried with v-sync on or off, turned replays off, all graphics settings on low but nothing has helped.
My Specs:
- I5 8600k hexa-core @ 3.6Ghz
- GTX 1080
- 16 GB DDR4 Gskill 3200mhz
- Asus Prime-A
- Kingston 500GB M.2 SSD
- and I have another SSD and a hard drive
