GPU monitor
Graphics utilization and video memory, across one card or several.
What it does
Tracks 3D engine utilization with a percentage, a colour-coded sparkline and, where the card reports it, video memory usage.
Two memory rows can appear. Dedicated is the card’s own VRAM. Shared is system memory the GPU is borrowing, shown when the driver reports both used and total. Utilization colours shift at 70% and 90%; the VRAM bar shifts at 80% and 90%.
If your machine has more than one GPU, a multi-select appears and each selected card gets its own panel. Switching which GPU a panel watches clears that panel’s history so the new card’s graph starts clean rather than continuing someone else’s line.
Where the data comes from
The graphics driver, sampled locally every 1 to 30 seconds. Works with NVIDIA, AMD and Intel.
Limits
- Integrated GPUs frequently report a dedicated-VRAM figure larger than the total the registry claims. When that happens the Dedicated row is suppressed rather than shown as a nonsense over-100% bar.
- Per-process GPU attribution is not available.
- Encoder and decoder engine load are read where exposed but not all drivers report them.
