Hi.
While I have an older CPU, I'm a 23-year veteran programmer and I write drivers for a living. I keep my computer VERY UNloaded (as close to 0% as possible), because I want/need the horsepower for more important things.
Firstly, I want to commend Corsair, as they have done a HUGE amount of things right. I've purchased RAM, power supplies, and especially keyboards (the only ones that let me type as fast as I want to, and do so accurately).
I just got another keyboard (K70 LUX) to add to a laptop I am using (older CPU, Intel i5, 8GB RAM (plenty, I don't use all of it) and 1TB SSD for main drive), and while I am very happy with the keyboard, iCUE software has made a turn for the worse, and I'm not sure when it happened. Specifically iCUE is taking 11-15% CPU despite the fact that all I want to do is lower the brightness of the LEDs a bit. I don't have any LED animation or changing going on. And I have made sure that all the sensor monitoring on the DASHBOARD is turned off (turning it on makes it go up to 30%!). This 11-15% loading is true including when the iCUE UI is not displayed.
I got an account on this forum because I was unhappy with how much CPU power iCUE.exe was taking. I suspect there are things that can be done with the iCUE (e.g. profiling) that would make it a great deal more efficient. A great deal of CPU loading is how efficient the source code is made. (Trust me, I live and breathe this fact every day in the drivers that I write. Sometimes I write in assembly language because CPU efficiency is very important in my work.) When all I want to do is lower the brightness of the keys a bit without any changing or animation, that shouldn't take any CPU (0% or unmeasurable). And given that I don't have any fancy patterns or animation going, in my opinion, < 1% CPU would be acceptible, but not 11-15%. I almost wish I could join your software/firmware team because I could knock down the CPU load by 10X I'm pretty sure.
Anyway, if you would please, pass this along to the development team, I would appreciate it. If I were their manager, I would be telling them to find out what is consuming CPU time merely to run LEDs.... Something isn't quite right.
Respectfully submitted,
Vic
