led's affecting performance is 100% due to firmware design
as a start, probably it's a good idea to not use interrupts anywhere

Wouldn't onboard memory to store and execute lighting profiles fix that problem? That would definitely be a hardware revision and probably inflate the price of the mouse even more and at that point why not add a switch on the bottom of the mouse to on and off the lighting at a hardware level?

Simple hardware revisions could fix these problems but that's not likely to happen since the mouse is already designed to be a software only mouse and redesigning it before they made back the cost of development doesn't make sense from a business prospective.

Take what I say with a grain of salt as I one don't own the mouse or have any plans to own this mouse and I'm not an designer or electronics engineer.

I've just been informed that this fix was actually already released on 2/8 as part of FW 2.01 with SW 1.15 for Scimitar, which is on our website now.

As for the led's effect on the mouse's performance? It's there whether the leds are on or off. 1000hz is where it's easy to demonstrate and feel.

Now I'm almost certain at this point that this is not completely fixable with firmware. As in, this is just bad design.

But if you can get your firmware provider to produce a firmware for you that fixes all the issues without removing, nerfing, or breaking features or performance then hat's off you guys.

That's definitely the goal. We want to make sure that everybody's so happy with their decision that all other options seem bad by comparison. Got some work to do there, obviously.

Thank you for the detailed feedback on the specific frequency. The more specific the feedback the easier it is for us to duplicate - and therefore, correct.

As you can imagine we can't possibly have every single test platform and situation duplicated in-house, which is why if somebody finds a bug, we do our best to replicate it, and that means getting all the info possible from the person who found it.


Can you share more details about your system config? Hardware config, OS, BIOS version, etc? It'd help us figure out how to re-create these issues.

Thanks dude.

i know it's standard procedure to ask about our system config, but i can assure you that the issue uaok posted (missing usb reports leading to random/unstable interval vs. time plots in mousetester) is entirely due to firmware. you can reproduce the issue on pretty much any computer.

as to how to fix it, i'm not sure what mcu you're using, but from my experience screwing around with avr's, i can offer the following general advice: always synchronize the mcu-sensor spi communication with the timing of the usb frames.

also any confirmation for what sensor this is? 3988?

NXP mcu, 3988 sensor.

I'm really too lazy to troubleshoot a mouse I don't really care about. tongue.gif

It was rather amusing though to experience it's problems. Haven't seen a mouse struggle with 1000hz since the 2005 Copperhead. That 12000dpi 1000hz rainbow light show clown cursor too. \o/

I got mine for $20. I feel sorry for people who paid any more than that.

also dat garbage tier button lag

All its missing is usb ports so you can charge your phone while you use 12k dpi.

Considering the mouse, it would probably just explode internally if that feature was added.

I wonder now if the Dexin / Tt Esports Bleck Element Cyclone would have clown cursor with the fan going.

I had never heard of that Tt esports mouse before, I think that takes the cake... +1 to corsair adding fans to this mouse to complete the package lmao

Concerning the issues with mouse polling rate and disconnects, Corsair has assured us that a new firmware update is due out in late December to address those rare system issues. As it stands now the mouse is functional at a lower polling rate. The following was a statement provided by Corsair’s Public Relations Manager:

“The issue Joe has found is a known issue with the current FW of the mouse. It’s not one we can replicate 100%, but it is known to happen, and it’s system based, not mouse based. We could ship a replacement, and the same issue would occur.

We believe it’s an issue with the way the USB protocol and the mouse communicate, and a fix is in the works. Currently this is targeted for a late December time-frame, as part of the mouse’s v1.14 firmware.


Sorry I can’t give a sooner fix, but as Joe’s found, dropping to 500Hz resolves it in the short term with little discernible impact. However, we’re aware that we need to deliver the mouse as promised, and will ensure the Scimitar RGB works as advertised at 1000Hz.”

Mail room clerks code this stuff I swear.

They will never fix it. I'm calling it now.
