Performance Monitoring

Maintaining a solid frame rate (typically 60fps) is essential for smooth interactives in TouchDesigner.

The Performance Monitor

You can open this via the Dialogs > Performance Monitor menu. It breaks down the millisecond cost of rendering every single frame.

• It lists out each node that cooked in that frame and how long it took.
• This is your primary diagnostic tool when framerate drops inexplicably.

Middle Mouse Button (MMB) Info

• Middle-clicking any node gives you information about its cook times. Look for nodes that take an unusually long time to evaluate, like heavy TOP operations or complex SOP manipulations.

The Probe

• Probe is an extremely useful external tool (built as a .tox by Derivative) designed to visually track CPU and GPU usage per node.
• You can find it in your Palette panel under Tools, allowing you to observe performance live in the network editor.
