Got my mouse today. Feels nice and seems to do the job on Default settings but the highest DPI you get in default mode is only 5,000 when it can go up to 10,000. Also, the RGB lightshow is pretty annoying in default mode. To modify the RGB lights or crank up the DPI settings you have to install the Corsair icue software that starts off life as a 500MB package that unpacks to a whopping 1.5GB of bloatware.When the icue software is running it consumes 200MB of memory (What in the actual hell) and 0–5% of CPU cycles. All I want to do is either turn the RGB off or set it to one colour and forget it but no. Not possible unless you run the bloatware in the background. Its a shame as the actual mouse function seems to be pretty good. Also, its a little narrow in my average sized hands.
