Mouse connected via bluetooth causes screen stuttering | Razer Insider
Skip to main content

Hi, I'm experiencing screen-stuttering while my mouse (Razer Naga Pro V1) is connected via Bluetooth. I'm positve that bluetooth connection is the problem because when I connected mouse via USB dongle (wirelessly ofc) problem goes away. You can see this problem in a youtube video I made (1min long). I read that such behaviour can be caused by bluetooth interference or poor bluetooth connection, but I don't know how this can be possible since my mouse is the only bluetooth periferial connected to my PC and there is around 20-30cm distance between my mouse and bluetooth antennas. I’m using TP-Link Archer TX3000E as my Wi-Fi & Bluetooth adapter

I think your screen stuttering may be caused because the polling rate might be pretty low; I would estimate a maximum of 250hz. That’s all I can suggest.

Do you know how can I change polling rate when im connected via bluetooth? Becasue this option dissappears form Razer Synapse 3 when you connect your mouse via bluetooth so I can’t even check it :/

I don’t think polling rate is the problem, when I changed it to 125Hz (usb dongle) in Synapse 3 I could see a little stutter but definetly not so much as in bluetooth connection.

I’m not entirely sure if you can change the polling rate from a Razer r] Pro Mouse (as I don’t own one), and also, I would imagine there being way more bottlenecks in terms of wireless connection - in general, but the 2.4GHz wireless shouldn’t be an issue in terms of transmission rate…

Hope your Naga Pro’s bluetooth will be figured out!

Yeah, It seems that bluetooth protocol bandwidth is the problem here :/
I used this website https://devicetests.com/mouse-rate-test to estimate my mouse’s polling rate. When connected via usb dongle average polling rate reaches ~980Hz, while connected via bluetooth it’s only ~135Hz.

Anyway, Thank you very much for your help.
