What is greygodzilla-pc-metrics?

Grey GodZilla PC Metrics is a portable Windows tool for keeping an eye on your computer's hardware while you use it, especially while gaming. It comes as a single executable file with no installer and no account needed, so you can download it, unzip it anywhere on your drive, and run it directly. Once running, the program sits in your system tray and can show a custom overlay on top of your games and other programs, displaying live readings for your CPU, GPU, RAM, VRAM usage, temperatures, power draw, disk activity, and network use. It also tracks frames per second and frame timing using a bundled tool called PresentMon, and the overlay comes with seven visual themes to choose from. The newest version adds an AI Stutter Advisor, which watches your system while you play and gives a plain-English verdict on why a game might be stuttering, for example pointing to your GPU, CPU, thermal limits, or memory pressure as the likely cause, along with suggested fixes you can actually act on. You can copy this diagnosis in a format ready to paste into Discord, or save it as a shareable HTML report to send to someone else for help. Beyond live monitoring, the tool includes a standalone benchmark with a score history so you can track how your system's performance changes over time, along with utilities for adjusting fan curves, checking your drive's SMART health status, scanning for Windows hardware errors known as WHEA errors, and monitoring network ping. The program can also be run from the command line, for example to trigger a quick benchmark or a self-test without opening the full interface. Since it is an unsigned application made by an independent developer, Windows SmartScreen may show a warning the first time you run it, which the README notes is expected and not a sign of a problem. It is released under the MIT license.
