I have the Razer DeathAdder 2013 that I purchased many years ago - it was in storage until recently and I decided to use it on my X99 rig.



The problem is that on my X99 rig, I am running Win 10 Pro and Razer Synapse 2 - which is meant for the DeathAdder 2013 doesn't work - only the latest Synapse 3 which is full of bloatware etc. works.



I've installed both Synapse 2 and 3 to test but I am not able to adjust the DPI on the mouse! The DPI is set to very high (9000 DPI?) and it's almost impossible to use normally.



How do I reduce the DPI (or adjust it) without Synapse or how do I make Synapse 2 work so that I can adjust the settings on the mouse?
