Just doing PC maintenance, unplugged all devices, plugged DAv3 Pro and Viper V2 Pro into different ports, than before. Almost all settings got reset - including DPI stages (on both mices).
Also DAv3 Pro is still facing DPI stages issue, that I’ve mentioned some time ago:
Sometimes it’s not possible to edit this setting, because sensitivity stages are not displaying in Synapse.
Synapse version: 4.0.76.501
