What’s Changed
GPU usage on macOS was previously reported significantly higher than actual values (e.g., 50–60% even at idle).
This was caused by macOS keeping the GPU clocked at a low P-state for display compositing.
This update now references the DVFS frequency table and applies a frequency-weighted usage calculation algorithm, resulting in more accurate GPU usage reporting.
Additionally, Intel GPU usage was not displayed on Windows.
A new monitoring method using PDH and DXGI has been added, enabling GPU usage monitoring on systems with Intel GPUs.
