About OCAT

The Open Capture and Analytics Tool records frame times and frame rate for D3D11, D3D12 and Vulkan applications and shows a live overlay, writing a CSV of every frame for later analysis. It is the tool behind many published frame-pacing comparisons.

Strengths

  • Per-frame CSV output, not just an average frame rate
  • Works across D3D11, D3D12 and Vulkan

Limitations

  • Windows only
  • Upstream activity is limited
