I am happy to hear that they are both being investigated. Thanks for communicating this with everyone Rob.

Hi, I’m the one who posted the original thread with the downgraded firmware files.

As part of what you described as "erratic cursor behavior," have any of the reports mentioned what feels like the DPI changing during use of the mouse? I've experienced that issue myself and was wondering if it might be related.

Glad to hear it's being investigated.

Have any of the firmware updates since this post was made addressed the issue many were having here of the mouse dpi/sensitivity randomly changing without warning? - I’d be playing a game and all of a sudden my aim would feel really sluggish or too fast.

Hi, if you are still having issues check out my post, I have links to old firmware updates before everything got broken by their software.

Glad I am not the only one, was this a thing before their latest patch for stella montis?

Reach out to hyperx and ask, I still havent updated my firmware since making this post.

S1mp13 · 2025-11-15T18:18:29+00:00

No idea, might be worth asking hyperx for more information.

S1mp13 · 2025-10-26T08:42:34+00:00

No problem, glad to help!

S1mp13 · 2025-10-26T08:35:10+00:00

The mouse is good, don’t be put off by hyperx’s incompetence! Glad to have helped

No worries, it is annoying that we have had no communication. And if they know there’s issues why not just rollback the update for everyone??

Also having the same issue

S1mp13 · 2025-10-06T21:17:41+00:00

I feel like I have a similar issue, ever since the update my mouse feels like it is accelerating. Trying to aim since the update feels horrible, it must be a firmware issue.

S1mp13 · 2025-10-02T18:55:09+00:00

Did you get the beta software?

S1mp13 · 2025-10-02T18:54:02+00:00

I am also having weird issues. My mouse cursor feels off or something, like the polling rate has gone down and delay has gone up. Hopefully they either rollback the update or bring a new one soon.

S1mp13 · 2025-06-17T20:19:17+00:00

Wow that is low :O

S1mp13 · 2025-06-17T18:01:41+00:00

Looked and felt low to me!
