"upgraded" as in bought a custom PC and had it built, then shipped. Worked fine for a few days, then the problem starts occurring in addition to an extremely low framerate for a 3080ti (~still 180 but should be way higher) but I could be misremembering that, though.
Recording videos does catch the issue on tape, but does not catch the severity.
