CUE2: Software Overview

The Corsair Utility Engine (CUE) is the software that drives the complex lighting and other features behind our gaming peripherals. While previous iterations of CUE have served this purpose well, CUE2 refines the user experience to make it easier than ever to jump right in and quickly customize your peripherals. With that in mind, here's an in-depth look at the new and improved CUE2.

New User Interface

CUE2 features a revamped user interface with hi-resolution images and UI adjustments that allow for the window to be resized to make the most of whatever display you're using. When you first start CUE2, you'll be greeted by the default profile in the top left corner, your devices with global settings, help, and advanced toggles in the center, a shortcut to the latest CUE patch notes at the bottom, and a shortcut back to the homescreen in the form of the Corsair Gaming logo in the top right corner. If you don't have a CUE-enabled peripheral connected, you'll see a series of demo peripherals so you can explore the different configuration and customization options available (this can be disabled in global settings).


Profiles in CUE2

Profiles in CUE2 can be customized with a unique profile icon and background. Now you can quickly identify what profile you’re working in as well as show off your favorite characters or games to match with your lighting effects. Profiles contain performance, actions, and lighting information, allowing for a great degree of flexibility between games (especially if you link multiple profiles to a particular game to switch between characters or classes, all with their own unique lighting profiles and actions).


Creating Profiles

To create a new profile, click on the hamburger icon on the left hand side of CUE and then the plus icon. You can then name the profile and set a custom profile icon and background image (with an option to blur the background image and adjust the transparency of tabs as needed). If you need to tweak these settings again in the future, just click the pencil icon in the hamburger menu while that profile is active.


Importing and Exporting Profiles

Profiles can be imported and exported by clicking on the icon with left and right facing arrows. You can then choose between import and export via the drop down menu. Please note that CUE2 can only import CUE2 profiles, legacy profiles created in CUE 1.X will not import correctly. Exporting a profile will save the name, lighting effects, and actions in the profile. However, actions may need to be remapped.


RGB Share

Want to try out a few advanced lighting profiles or want to share one of your own? Corsair RGB Share is a resource we've put together for the community to easily share their custom profiles with the world.


Lighting in CUE2

Lighting effects in CUE2 are split between basic and advanced. Basic mode includes a selection of preset lighting effects that you can modify color, speed, and direction (depending on the effect) while advanced mode allows you to create complex effects from scratch with a greater degree of control.

Basic Lighting

We include a variety of preset lighting effects for basic mode such as the popular spiral rainbow and type lighting. These effects are applied to the entire keyboard, but can be layered on top of each other to make a rather impressive light show. Visualizer modes and the Lighting Link feature to sync up all connected CUE-enabled peripherals are included in the basic mode.


Here’s an example of setting up basic lighting:

  1. Create a new profile by clicking the hamburger icon to the right of the profile icons, then click “+” to add a new profile to the list.
  2. The "Create Profile" options will appear below the onscreen keyboard preview. You can name the profile, link it to a specific program, and add a custom icon and background for the profile here. Make sure to save.
  3. Click on “Lighting Effects” to the left of the preview area, then click “+” to create a new effect.
  4. At the bottom of the screen you’ll see the current effect preset (default is the spiral rainbow). Make sure to name the effect in case you plan on adding additional effects later. You can change the effect used via the drop down menu and tweak things such as color, speed, and direction depending on the particular effect you’re working with. Again, don’t forget to hit save once you’re done tweaking the effect to your liking.
  5. You can add additional layers of lighting effects by repeating the process we just went through. Layers are prioritized from top to bottom, meaning that layers at the top of the “Lighting Effects” bar will be on top of layers that are lower in the chain.

Advanced Lighting

By toggling the “advanced” switch at the top of CUE2, you enable advanced lighting features that allow you to make your own lighting effects and apply them how you want across your peripherals for a higher degree of customization.


Here’s an example of setting up advanced lighting:

  1. Toggle the “advanced” switch at the top of CUE to enable advanced mode.
  2. Create a new profile by clicking the hamburger icon to the right of the profile icons, then click “+” to add a new profile to the list.
  3. Name the profile, link it to a specific program, or add a custom icon and background. Ensure that you save these settings.
  4. Click on “Lighting Effects” to the left of the preview area, then click “+” to create a new effect.
  5. At the bottom of the screen you’ll see the current effect, use the drop down menu to change the effect type as you wish and customize colors, speed, velocity, triggers, etc. as you wish.
  6. Name the effect and highlight the keys this effect will apply to (click and drag a box around the keys, or control+click to select individual keys). Make sure to save.
  7. Continue adding layers of effects by hitting the “+” icon, or you can duplicate an existing layer or import effects from the library. Effect priority is the same as in basic mode, so layers at the top of the stack will visually be on top of all other effects on your device.

Actions in CUE2

Actions in CUE2 are listed on the left hand side with easy to reach controls for creating actions, duplicating actions, saving to library, importing from the library. When you create an action, you can choose between a macro, text, key remapping, media controls, timers, disabling keys, and profile switching. With actions you can do things such as remap a key so that it imitates holding a key, set a key or group of keys to be disabled when the lock is on, or automatically group profiles linked to the same program for easy switching between profiles for different characters or roles.



If you've got a VOID RGB headset, you'll be able to quickly toggle EQ settings, switch between stereo and Dolby 7.1, adjust sidetone/mic volume, and manage the InfoMic with ease thanks to the new, streamlined layout.



Performance Settings

Performance settings in CUE2 allow you to adjust angle snapping and pointer precision for mice and lock button behavior for keyboards.


Global Settings

CUE2’s global settings can be found by clicking on the gear icon next to the advanced mode toggle. While in global settings, you can update device firmware, adjust the polling rate for mice, check for CUE updates, startup behavior, and enable CUE SDK functionality. You can also turn off demo mode by checking the box to show only connected devices while CUE is running.


Need Help?

If you find yourself stuck at anytime, try clicking on the help icon just below the settings icon at the top of CUE2, this will trigger a tooltip to guide you through the different options that are available to you. Otherwise, the Corsair User Forums is a valuable resource for tips and tricks from us and the community.


Imagination Visualized

With CUE2, our goal is to unleash creativity expressed through powerful software and advanced RGB lighting. CUE2 will be supported with regular updates to introduce new features and we're constantly looking for feedback from the community (if you have feedback or feature requests, let us know in the Corsair User Forums). Thank you for all your input and we look forward to seeing how CUE evolves in the future.
