Viper Ultimate tracking issues on wireless

Does the stuttering change when you’ll move the dongle closer to the mouse (also avoid any electical cables / other devices that are using USB 3.0 cables etc).

The best is to test it in a different environment if possible (at least different room) to check if it’s a problem of some RF interference or not.

Exactly the same with the dongle right next to the mouse (on the dock) have tried changing usb ports, not using the dock. It has been fine for months and nothing has changed 

So as said earlier - try different environment (at least different room if possible). If it’s the same, then maybe the dongle is faulty.

Tried it on my laptop (usually on my desktop) in a different room, same results

Hey there, ​@ValiantHD 

Thank you for sharing your concern here regarding the tracking issues with your Razer Viper Ultimate. Could you please let me know if the issue still occurs when Razer Synapse is not running in the background, and whether the stuttering happens only when using the wireless dongle or also when the mouse is connected via the wired cable?

Please send me a PM together with your device's serial number and proof of purchase/receipt in PDF format so I can check its warranty details for a possible warranty claim. You can upload your proof of purchase to your Google Drive and send me the link. Make sure that the link is set the sharing settings to "Anyone with the link can view". Thank you!
