Desktop Hardware Monitor · Low-Overhead CPU/GPU/RAM Telemetry
Native Windows hardware telemetry widget engineered in C# and .NET (WPF) on top of LibreHardwareMonitor kernel drivers. Designed as a zero-bloat alternative to heavy OEM gaming overlays, polling CPU package temperatures, core clocks, GPU hotspot thermals, and RAM allocation with less than 0.2% CPU overhead.
Zero-Bloat Kernel Sensor Telemetry on Windows
Commercial hardware monitoring suites often bundle background telemetry services, RGB controllers, and Chromium-based overlays that consume hundreds of megabytes of RAM and prevent CPU C-state idling. [Desktop-Hardware-Monitor-Widget](https://github.com/FrancescoCastaldi/Desktop-Hardware-Monitor-Widget) provides an ultra-lightweight native C#/.NET alternative.
Resource Footprint Benchmark
| Telemetry Solution | Idle RAM Footprint | Background CPU Usage | UI Rendering Engine | Sensor Polling Latency |
|---|---|---|---|---|
| OEM Gaming Suites | 380–650 MB | 1.8% – 4.2% | Electron / CEF | 1,000–2,000 ms |
| Standard Task Manager | 45 MB | 0.8% | Win32 / XAML | No CPU package temp |
| Desktop Hardware Monitor Widget | < 18 MB | < 0.15% | Native .NET WPF DirectComposition | Configurable 250–1,000 ms |

}Architectural Highlights
- Direct Hardware Polling: Reads CPU core loads, package temperatures, GPU core/memory utilization, and system RAM commitment. - Minimalist HUD: Clean, low-cortisol typographic layout that stays unobtrusive during heavy compilation or 3D rendering workloads.
