As with the update to 3.5.1 in the preview Channel, updating to 3.5.5 stable made this bug came back. GPU is oscillating between 200 and 1040 MHz, creating stutters and framedrops in game. Setting GPU to manual mitigate the issue, but this Is very annoying for a stable update. Just making a post to gather all of us and maybe get some attention from Valve.
3.5.7 stable came out like 30 mins ago but does not address the 200-1040mhz bug. Sucks cause now I don’t even want to play games on it until this is fixed so as to not ruin my experience with the OLED.
