Razer Synapse causing mouse lag

I highly recommend that you perform a clean installation of the Synapse following this guide. That said, do you mind sharing a screenshot of your task manager highlighting Synapse on the processes tab?

I ran a clean installation of both versions of Synapse, following all aspects of the guide. Attached is a clip of my full Synapse task in Task Manager. This is not while a game is running, as the grotesque lag occurs only during gaming. Running as admin has helped a bit, but it will continue to happen when i have other background processes running. This did not happen with Synapse 2.

This does not seem to be a simple case of memory leak. We may have to dig deeper. Do you mind indicating which mouse you're experiencing the input delay in, and do you get the same results with and without Synapse running in the background?

Jumping back into this thread because the issue kept arising. The only solution I found to work was to uninstall everything from Razor and go back to using Synapse 2.0. I could not get Razor Central/Synapse 3.0 to consistently work no matter what. I tried running in admin mode, clean installs, updates, etc. Using Synapse 2.0 works every time and gives me DPI changes on-the-fly as I highly prefer. With 2.0, I'm also able to customize my mouse and keyboard still. My blackshark mic won't work without 3.0, but fortunately I exclusively use an external Audio-Technica mic.
