Perform Mode is an optimized mode for live performance that only renders a specified control panel: The rest of the TouchDesigner network editing interface is not rendered while in Perform Mode. If the TouchDesigner starts in Perform mode, the extra memory the Designer interface requires will not be allocated.
Under Dialogs -> Window Placement, you can set a flag to start TouchDesigner in Perform Mode: After you write out the
.toe, and anyone restarts the
.toe, it will open only a control panel in floating window, with no networks visible.
When you press the Esc key with the cursor over the window, it will open the full network editing window, Designer Mode, where you can view and edit the networks.
Click the [^] icon on the left of the top Layout bar to switch to Perform Mode on the fly. Then press the Esc key over the perform window to flip back to Designer Mode.
The function key F1 will by default, put you into Perform Mode. F1 is a Macro.
You can go into Perform Mode using python:
ui.PerformMode = True. See UI_Class.
