Hello, long time not coming in here. The tdp slider in decky, appears only when I use an external video card connected with my gpd win mini through oculink, but when I use it standalone, I don't have that option anymore and I have to rely to a third party plugin like powercontrol or simpledeckytdp.
Anyone knows what could cause this behaviour?
