Seems Kernel 5.12.14 has cured the issue of the GPU running at 100% all the time. (Zen tested, likely every variant, though). Batteries in all laptops heave a sigh of relief.
FYI, Happy Gaming, may the luck of the Seven Pillars of Gulu be with you at all times.
Nope - there was a bug that would push the GPU clocks to 100%, making the card gobble energy. I don't think it effected all AMD cards, by my Vega 56 and RX 5600M were effected. It showed up in 5.12.13
