Originally when I got my Legion 7 Corsair iCUE 3 was near enough the first thing I uninstalled because at the time it was clunky and ate the battery due to poorly implemented framework and services. This week I decided to take a look to see if having been upgraded by Corsair twice in that time period it was any better. Version 5 is a completely different beast and adds some very cool features like integrated game lighting for titles that support it and something called Murals.
Murals is what I am more impressed with, you can utilise predefined static images or video loops, create your own, or have the keyboard lit based on what is on screen with a feature called screen monitoring.
I'm using that screen monitoring and find it's actually quite immersive compared to using a static or animated rgb profile that has no context.
Of course the normal RGB profile options are there too and it's easy to switch from mural mode to normal RGB with a click of an icon in iCUE's interface.
The application also has a smaller footprint because it's now reliant on a modular plugin approach, so you only need to install the necessary plugins rather than a shed load of code for devices you don't actually own.
With regards the impact on battery, it is much better than before but still not perfect. However exiting iCUE 5 now also terminates all background services too unlike version 3, so as long as you remember to do that on battery power you can have your cake and eat it now figuratively speaking
All in all, it's well worth another look if you have been avoiding it until now like me.
