Using Blackwidow Chroma / Naga Trinity / Firefly.
I can confirm up until this day (19-10-24), that synapse is still bugged in version 4.
Been using version 3 and i’m reinstalling it, games are unplayable at the moment.
Keyboard macros bugging.
Mouse modifiers interfering with ingame KEYBOARD keybinds.
One keystroke and/or mouseclick makes the device keep repeating itself, like a loop sequence.
Synapse is taking forever to load and then it even, does not load interface graphics fully.
(personal experience)
All this fancy rgb led and the quality of the hardware, is overprized compared to other brands. If you play MMO on regular or more basis, you can expect your mouse to last about a year and a half.
