Just updated to the latest firmware available on Razer Support for my 2025 Razer Blade 16 and I am now experiencing inconsistant brightness that changes by itself often on Battery and sometimes when Plugged-in. So hard to submit a ticket to Razer Support…… Then the worst is sudden huge performance drop after gaming for about an hour of gaming. Im forced to restart the program to get the original performance. 165fps+ on Overwatch down to only 60-80fps, Dead Space Remake 140fps+ to less than 60fps.

 

Now Im very regret updating the firmware. Anyone know a way to fix this issues or to roll back the Bios etc.


Tested Game: Overwatch, Dead Space Remakre, Helldivers 2
