Dear DTS The Razor Deathadder Elite comes with two DPI switches just under the scroll wheel. Until two days ago, these two buttons were not mapped to DPI changes but to my Super and Class ability respectively. Two days ago, for some unknown reason while playing, my mouse died from a functional perspective in Destiny 2. The mouse was fully functional in MS Windows, but unresponsive in Destiny 2. I.e. I could not rotate my view, or use any function associated to any buttons including firing of my weapon. Imagine trying to complete a matchmade strike (Warden of nothing) with no way to fire a gun or to even rotate your view to check where you are running. I closed Destiny 2, restarted my PC and everything return to normal, .......sort of. The remapping I did for the DPI switches in the Razor Synapse software does not work, instead just changes the DPI of my mouse! The remapping was done as follows: Razor Synapse Software: In the Razor software I map the DPI up button to the zero key (not zero on the keypad, but zero above the letter keys). I map the DPI down button to the nine key (not nine on the keypad, but zero above the letter keys). In Destiny 2, I map my Super activation to key nine and my Class Ability to zero. I used this set-up for more than a year now with absolutely no problem before, and even now in the software the configuration is still the same as the last year. Is there any know issues regarding this and any advice? Although this is a minor issue as I still can use key Q and F for class and super, I changed to the mouse buttons for a reason and want to revert to the mouse configuration.
