A real-time processor and thread diagnostics tool tailored for dual-CCD AMD processors such as the AMD Ryzen 9 7950X3D / 9950X3D (CCD0: 3D V-Cache vs CCD1: Frequency).
Designed specifically for heavy multitasking environments (like VRChat, SteamVR, and modern games), this tool lets you verify whether latency-sensitive rendering and physics workloads are safely hosted on 3D V-Cache (CCD0) while background tasks, audio, and network threads are offloaded to the high-frequency cores (CCD1) to preserve critical headroom against stutter.
- 100% Anti-Cheat Safe (Zero-Risk)
- Fully safe to run alongside games protected by Easy Anti-Cheat (EAC), BattlEye, Vanguard, etc.
- No memory injection, hooking, or intrusive DLL scans. Strictly queries safe, non-invasive Windows API performance metrics.
- High-Accuracy Thread Role Estimation
- Accurately pinpoints the process's initial
Main/GameLoopthread (Primary Thread: 100% certainty). - Automatically classifies active threads (
Render/Gfx,Physics/IK,Audio/Network,Worker) based on real-time CPU cycle consumption ranks.
- Accurately pinpoints the process's initial
- Dual-CCD Parallel Inspector (CCD0 Top 5 vs CCD1 Top 5)
- Side-by-side inspection of the top 5 heaviest threads on each CCD.
- Instant visual indicators (
⇄orange icon) whenever a thread migrates between logical cores.
- 🖥️ System Total CPU & Per-CCD System Usage Live Gauges
- Displays overall PC-wide CPU utilization alongside individual CCD0 (V-Cache) and CCD1 (Freq) total loads in real time, letting you easily correlate the target game's distribution with full system activity.
- Dynamic Auto-Resizing & Collapsible UI
- Click the collapse button to automatically shrink the window height down to a compact 250px HUD.
- Expand anytime into a full 560px detailed diagnostic dashboard.
- ⚡ Live Power Plan Badge & Warnings
- Displays active Windows power plan (e.g.
Balanced). Instantly alerts you if switched toHigh Performancewhich inadvertently disables core parking on dual-CCD Ryzen processors.
- Displays active Windows power plan (e.g.
- 🎯 Live Process Priority Class Monitoring
- Real-time inspection of the target process's priority class (
Normal,High,Above Normal, etc.), allowing you to immediately confirm whether launch arguments (e.g.--process-priority) or registry priority tweaks are actively applied.
- Real-time inspection of the target process's priority class (
- 📌 Always on Top Toggle
- Easily toggle always-on-top mode on or off to send the window behind other applications when needed.
Real-World Inspection (VRChat under heavy load): Core gaming workloads (
Main/GameLoop,Render/Gfx, andPhysics/IK) are cleanly packed into the 3D V-Cache on CCD0, while background tasks (Audio/Network, worker threads) are offloaded onto high-frequency CCD1.

Requires Python 3.10 or newer (Standard library only; no pip dependencies required to run):
python ccd_monitor.py
# Or double-click start_monitor.batpip install pyinstaller
pyinstaller --noconsole --onefile --clean --name "X3D-Thread-Inspector" ccd_monitor.pyOutputs standalone executable to dist/X3D-Thread-Inspector.exe.
This repository includes a ready-to-use GitHub Actions workflow (.github/workflows/build.yml):
- Every push to
main: Automatically builds on a clean Windows runner, tags a new version (v0.0.1→v0.0.2...), and publishes a GitHub Release with standalone.exeand.zippackages. - Manual trigger: You can trigger a release with
patch,minor, ormajorversion bumps directly from the GitHub Actions tab.
