Repeat scroll up/down slow when synapse is open?

Hi there! Thanks for posting your concern here. The Razer Synapse should be launched or established in the background to execute all its features such as Chroma connect, macros, and profiles. You will notice this while your computer is launching, it will only give you the defaults Chroma effect, but once you are logged in and Synapse 2 or 3 launched, it will trigger all the expected features. Should the issue persists after the Razer Synapse started, please follow the steps below:

"Clean reinstallation of Razer Synapse with registry delete."

Note: Please be careful and not delete other files/folders as it may corrupt your Windows operating system. Check the steps below:

1. Uninstall Synapse and delete all files in C:\Program Files (x86)\Razer and C:\ProgramData\Razer directories. These folders are hidden by default, so please be sure to unhide them.
2. Uninstall Razer drivers by going to "Device Manager" from Control Panel.
3. Press Windows + X key and choose Command Prompt on the menu.
4. Type regedit in the command prompt window and press enter.
5. Please go to this path and check if you have it:
HKEY_LOCAL_MACHINE\SOFTWARE\WOW643NODE\Razer\
*Please delete everything that's in the Razer folder. Please reinstall Synapse after deleting all the files inside the Razer folder
6. Download a fresh installer and reinstall, then restart your PC.
7. Add Synapse to your firewall exemptions and update your .NET Framework at https://dotnet.microsoft.com/download/dotnet-framework/net48

I'll be locking this thread. Feel free to send me a PM should you need additional assistance.
