Recenetly I upgraded my GPU as I planned on upgrading my monitors from 1080p 60hz to 1440p 144hz. I went with a RTX 2060 as I read that it's capable of running 1440p 144hz on medium settings in most games. After getting the new GPU and monitors, I noticed that I can't reach 144fps to take advantage of my 144hz monitor. I tried fortnite as a test, on medium settings (except render distance) at 1440p 144hz I was getting random fps jumps between 50fps and 100fps, sometimes it drops to 30 for a second and back to 50-100, from time to time it will jump up to 120 but never further than that and it will never level out. I did notice that the GPU is running around 50%-70% useage while my CPU is pinned at 100% which I never had this issue before, my CPU is a i5 9600k, could this be the issue? I have the ability to overclock it but no idea if it will help since my cpu is pinned at 100%, I never overclocked it because I never had the need to. My temps are normal (50C GPU 50-60C CPU and CPU is turboing correctly) My specs:
CPU: i5 9600k (not oc'ed)
