Logitech wireless mouse freezing on Windows 8.1

Hi guys,

Having an issue with my new PC build (Windows 8.1 x64) whereby my Logitech MX Performance wireless mouse lags and stutters at random intervals while doing a variety of tasks. Does anyone know of a fix? There seems to be a lot of information relating to the RC version of Windows 8.1, but I can't find anything conclusive.

Maybe similar to this?? How far is the mouse from the receiver?

Hmmmm! Go to Google and check . "Logitech MX performance Windows 8.1".

Thanks Speedy - have moved the dongle to a front USB port to see if this helps. One thought I did have is whether the PCI wifi card may be interfering with the dongle? Presumably they both run at 2.4Ghz?

FWIW I have the same setup MX mouse, Win 8.1, 64bit and it runs without problem. Your Logitech unifying software is up to date?

Hi Clive, no, I must admit I'm just using the default drivers that Windows installed - that's a excellent point. Will check this out tonight

I think I've found the culprit - I'd somehow failed to notice that Device Manager was reporting an issue with the SM Bus Controller - installed the latest chipset drivers for my motherboard, and the jerky issue seems to have stopped.

Next question - is it advisable to download the generic Nvidia drivers for my GPU chipset (GTX650) or should I wait for the manufacturer-specific version (Gigabyte GV-N650OC-2GI)? Gigabyte just seems to be a wee way behind in terms of updating this.
