Ever since installing my new rx 5800x cpu, when I launch fortnite I get three beeps. The odd part is it only happens when my rendering mode is on dx 11 or performance mode. When i play on these modes I get terrible fps drops every few seconds. Although I get a nearly contstant, stable 240 fps on dx 12 and no beeps. the sound of the beeps are in linked video amd beeps help. any advice would be appreciated.
