I have a 9800x3D+4090 sff build, and it works great, but in fortnite once every 5h game session it just completely stutters for a split second once and then doesn't do it again. What's causing this? The game is running perfectly fine @ max refresh otherwise.
Running the ram @ 6000mhz, and is the only change to bios I've made.
