I just put together a new PC with an XFX 5600 XT, I played Valorant on and off for a total of 4-hours and according to my experience and the AMD control panel I was getting 400 FPS. One morning after playing I started to play and was getting a glitchy 60-100 FPS.
I've changed no settings, I don't overclock anything, I haven't installed anything new, and I have the latest drivers.
Any advice?
