GPU-CPU-System-Performance-Analysis-Tool

A Python-based GUI to interface and display real-time systemperformance metrics from:

• Nvidia NVML (GPU Utilization, VRAM, Power, Temperature, etc.)
• Intel PresentMon (Frame Times, GPU Busy per frame)
• psutil (CPU usage, CPU interrupts, RAM usage, process monitoring)

About.

• Built to display metrics on an ultrawide 21:9 monitor while running 16:9 games, without covering game screen space.
• Exposes extra statistics like CPU interrupts and GPU Busy not typically available in MSI Afterburner or Steam overlay.
• Brings all system and frame metrics into one easy-to-use tool with real-time graphs and CSV logging.

How to use.

1. Download PresentMon

• Get the latest PresentMon release.
• Rename the ".exe" to 'PresentMon.exe' and place it inside the PresentMon folder.

2. Install Dependencies

pip install psutil matplotlib pynvml

3. Run the Overlay

python main.py

Bugs / Issues

• Sometimes PresentMon doesn't want to start, i've found that restarting your computer will usually fix this.
• Currently only Nvidia GPU's are supported, but I've seen that there are drop in replacements for NVML if you would like to use an AMD GPU.

To - Do

• Add Nvidia SMI support.
