Have the Zephyrus S17 with RTX 3070 and advanced Optimus.
When Adv. Optimus is activated, i get micro stuttering in all games. (Temps are fine, games run smooth, only one hard stutter every 30sec or so) When I click on (normal) Optimus (in Nvidia control panel) then the stuttering is gone. But then I dont have Gsync.
Stuttering is also gone, when I activate "dGPU only" in BIOS.
This problem was mentioned a few times in other forums as well.
Advanced Optimus seems to be bugged. Anyone has an idea?
