EVGA Precision X1 vs Polychromatic

EVGA Precision X1 is free GPU tuning software for Windows, with controls for clocks, voltage, fans, RGB lighting, and monitoring. Its OC Scanner tests a graphics card for a stable overclock and offers additional testing modes. Users can set GPU and memory clocks, voltage, and independent voltage and frequency points. Fan speed, curves, and profiles are adjustable, though the available options depend on the graphics card. RGB controls cover graphics cards and NVLink Bridges; LED Sync can coordinate with other EVGA RGB components. On supported EVGA cards, the software provides real-time wattage monitoring and an on-screen display of system vitals. It supports up to 10 profiles with hotkeys and includes an in-game screenshot function. Listed system requirements specify GeForce RTX, GTX 16 Series, and GTX 10 Series cards, plus Windows 10 64-bit or Windows 8 64-bit. EVGA offers a standalone version and links to a Steam version. The listed GPU control features require EVGA graphics cards.

Polychromatic is a free, open-source GNU/Linux frontend for OpenRazer. It controls lighting and other settings on supported Razer peripherals, with the home page listing more than 210 devices including keyboards, mice, mouse mats, and headsets. You can adjust built-in effects, brightness, DPI, and polling interval, or create static and animated mappings from pixels and frames for games, applications, or ambience. The app shows firmware versions and serial numbers and can test individually addressable LEDs. A tray applet provides settings access when the desktop supports system-tray indicators, and a troubleshooter addresses problems such as OpenRazer failures or missing devices. It runs locally without cloud services or a login and is licensed under GPLv3. Polychromatic supports OpenRazer only; other brands are unavailable, and key remapping is not supported.
