Windows 10: INSANE lag spikes and stutters in fortnite!!!

INSANE lag spikes and stutters in fortnite, HELP!

I stopped playing fortnite about 2 years ago and it used to work perfectly there were no lagspike/stutters, and i wanted to come back to the game now. I started a solo match and when i got into the game i was getting insane lagspikes/stutters, i was pretty confused, i looked up some videos and stuff on youtube how to fix this issue but none of them have helped yet. My fortnite is installed on my SSD which is my C driver and it currently has valorant installed on it too with 50gb of space left. Valorant on the other hand works smooth af over 60 fps no probem, no lagspikes, no problems, i also play genshin impact that also works smooth and good, my drivers are up to date. I have tried capping my cpu % as in youtube videos its said that 100% cpu usage is most likely the problem, capping did not help instead it decreases my GHz speed from 3.36 GHz which is the max to 1.19Ghz which is the base GHz. Fortnite takes 3.6 gb of my ram when its running 60% of my cpu. What happens is every time i get a lagspike/stutter my game freezes for about 5 - 15 sec and everytime it does this my ping seems to go really high up always above 300ms and when its not lag spiking which is rare its back down to 30 - 50.
I under stand my cpu is not the best nor my graphics card but the thing is when its not lagspiking my fps is above 40 always, which is all i need. I would really love to get some help

INSANE stuttering in Fortnite Chapter 4

Dear Dr.Vivek,in this case I suggest you try to uninstall and reinstall FORtnite;

Then leave Windows in performance mode;

Right-click on the start menu and go to System;

Click Advanced System Settings;

In the Performance section, click Settings;

Check the Adjust for better performance option and click Apply;

Check if the stutter still persists in Fortnite;

See you soon!
