I need to have LG Hub to set up the mouse anyway, the same software controls the KB lights too, and never had an issue with it.
Logitech's is one of the least offensive from a bigger company. Not perfect, but fit for purpose at least, and Logitech isn't trying to integrate with motherboards and GPUs and memory sticks and so on which is where you really get into trouble, in my experience.
There is a reason I've preferred running case fans off of physical controllers or a basic built in fan controller like Fractal used to put on their cases.
A lot of cases have an 'RGB' button linked to a controller. I haven't seen one that can't be bypassed yet, and most (but not all) seem to swap the RGB button for the reset button.
And there are also dedicated controllers; I have one from CoolerMaster that works with SignalRGB well enough, and AquaComputer has their line of RGBpx stuff that integrates with their
Aquasuite software. Both controllers hook up via USB, I recommend getting a powered internal USB 2.0 splitter for this stuff.
Well, I don't recall any of the X570 Aorus boards doing it if that's what you are wondering. Nor anything prior to that. Z690 Aorus boards didn't do it either as far as I remember.
B550 Aorus and Z690 Vision D, default rainbow puke to the moon for what I've seen. Luckily SignalRGB has no trouble with the Gigabyte boards themselves; DDR5 is a whole nuther matter.
Man, that will be amazing. All these other vendors basically make garbageware you have to use in order to take your lights out of unicorn vomit mode.
We have every reason to expect Microsoft to cluster this initiative, but on the off chance that they don't meet everyone's' expectations and wind up producing something useful, I'll be personally both relieved and impressed.
