I've recantly upgraded my gpu to a 1070 but iits underperforming on on certain tasks. When i benchmark test it, it performs really well and i dont have problems. I also have no problmes when i play CSGO. When i play fortnite the FPS dips are huge. I cant play at 144fps when the PC should be able to do that comfortably. All drivers are up to date and I have a Ryzen 7 2700x cpu that isnt going to underperform. I'm wondering if my 450W psu is the reason for this? I'm not very knowledged on computers and i have been trying to troubleshoot for the past 2 days, I'm stuck.
