Thanks for providing info about it, if i’m not wrong when the power indicator starts blinking it means it’s fully slept (ram only)

I’m having none of the issues you mentioned. Did you update every driver from asus’s website+bios  with nvidia drivers? I have scar 16 4080 with miniled and everything is working fine without issues like dimming etc.

The problem is gone for me, it’s fixed with latest nvidia driver. Frametime is really smooth now on ultimate gpu mode.

Nice, now there is only this problem left https://rog-forum.asus.com/t5/gaming-notebooks/rog-strix-scar-18-gsync-and-screen-off-will-balck-screen/td-p/943531
