It’s possible that the option for Advanced Optimus might disappear from Razer’s new Blade 18 (2023) gaming laptop after updating the Nvidia drivers, here’s how to fix it.
I only experienced this issue once, so did not mention it in my review of the Blade 18 as I thought it was just a weird one off, however other people have also reported the option for advanced optimus disappearing.
Razer have provided BIOS version 2.02 under the drivers & downloads tab on this page to fix the problem.
The fix was published on February 25th 2023, and notes: “Fix DDS function missing issue on unit with BIOS 1.01 after updated to NV GPU public driver 528.xx”
DDS stands for Dynamic Display Switching, also known as Advanced Optimus, so following the update steps on that page should fix the problem.
