Tartarus v2 keymap switching is sluggish

I’ve only noticed this recently, but switching keymapping takes almost a half second when it used to be near instant. That delay makes the feature basically unusable :(
I’m using Synapse 4.
Issue persists if I use “next Keymap” or “specific Keymap” and check or don’t check the “switch back to previous Keymap...” option.

    Same happening with Tartarus Pro-I have tried both. Its been really noticeable after switching to Synapse 4 from 3. The opposite of a precision instrument, and tough in action/mmo stuff.

    Ehi Razer, where are you? After almost 3 moths from my request (I already did all the things you asked me to try solving the issue without success) the bug is still there, do you think you will ever fix this?

     

    Please, I need the switch function and now I have a permanent delay which creates several difficulties in using alternative key values for quick actions.

     

    Please, do something to fix the issue.
