I came to the conclussion my GPU was dropping PWR to protect itself from temp spikes. Lowered graphics options (cap at 60 fps and medium + some fidelityFX super res 2 at ultra performance) and never had the problem again. Still, this downgrades the gaming experience a lot.
I’m running a Rog Strix G513QY with Ryzen 5900HX and Radeon RX6800M on a 4k monitor without high resolution assets installed.
