Software

Software settings for the Ironclaw RGB can be accessed using iCUE, Corsair's all-in-one driver software for their newer products. The software is well designed, but a tad over-complicated and slightly cluttered in my opinion. At the top right is a Settings button which contains the polling rate, on-board memory cleaning, lighting brightness, and firmware update options. The top-left area contains a small window that contains the profiles, of which you can create an endless number as far as I can tell. These can be linked to be triggered on specific executable launches as well.

Below the profiles are the main setting tabs. The Actions tab contains all the button-mapping and macro-creating functions, which are again unlimited. Next is the Lighting tab you can read about in the lighting subheading below. The DPI tab has the CPI settings (DPI is the wrong term as it means dots per inch while it should be counts per inch); there are six available stages, including the sniper setting. You can set a default value and even turn off all stages except for one if you feel like it. You can set different colors to these CPI levels, which will light up between the two CPI buttons on the mouse.

The Performance tab doesn't have many options, and I would have put the polling-rate options here instead of the Settings menu. You can find the option to turn on angle snapping here, as well as the two basic Windows options. Lastly, Surface Calibration offers the possibility to change the lift-off distance according to the surface the mouse is being used on. I would suggest using this function because the mouse has a high LOD by default.

The Corsair iCUE software consumes around 20 MB of memory while running in the background and takes up a staggering 410 MB of disk space in my configuration. Once you set everything up, you can simply uninstall it if you don't want it installed because the mouse has on-board memory.

Lighting

Just like the other two new Corsair mice, the Ironclaw RGB too has highly customizable RGB lighting with two zones: the scroll wheel and rear Corsair logo both light up according to the set settings. All effects look great, the lighting is bright and vivid, and the transitions are very smooth.
