Could you build this?
Partial Building a simple UI in Rust is feasible with LLMs, but writing low-level Windows kernel/registry tweaks, reliable game process hooks, and accurate DirectX/Vulkan frame-time measurement requires deep OS-level systems knowledge.
What it would actually take: The app requires Rust interfacing with the Windows Win32 API, ETW (Event Tracing for Windows), or PresentMon hooks to capture frame presentation timing and calculate 1% lows. Implementing safe, reversible OS performance tweaks involves modifying complex registry keys, power plans, and system service states without bricking the operating system. This demands specialized knowledge of Windows internals and graphics subsystems.
