rival 3

I have a Rival 3 and no matter what game I'm playing I get this weird problem where my frames drop massively once I start moving my mouse, but when I just use my keyboard my framerate stays at a smooth 60. I've heard this can be caused by high polling but I checked out my mouses polling and it...

So I started a firmware update yesterday for my Rival 3 and it still hasn't finished, the lights on the mouse are still flashing, but I don't know if there has been any progress. Is it normal for steelseries firmware updates to not have a progress bar?
