The monitoring side tracks temperatures, storage, memory, graphics hardware, fans and liquid-cooling pumps in real time, and can spot conflicting applications and close them, so overlapping utilities do not fight for control. HYTE says the app will also flag issues that need attention. On the performance side, gamers get automatic frame-rate tracking covering average FPS, 1% lows, individual sessions and performance history.

Lighting is handled through the OpenRGB SDK, the cross-platform RGB project that reached version 1.0 in September, meaning compatible hardware from multiple brands can be managed in one place rather than through separate vendor apps. Nexus also adds customisable widgets for system and media information on monitors, all-in-one cooler screens and supported displays, with HYTE planning to widen screen compatibility over time. A web client and mobile app allow remote monitoring and adjustments away from the desk.

On resource use, HYTE claims the app occupies under 50 MB at launch and consumes 0.1% to 1% of CPU, GPU and memory resources. TechPowerUp's own testing recorded roughly 142 MB of RAM, well above the sub-50 MB launch claim, though CPU use of about 0.2% to 0.5% fell within the claimed range. The reviewer noted a fresh reboot might change the result.
