Hi everyone, I’m seeing a very short but clearly visible stutter every few seconds while rotating a point cloud. The project otherwise runs steadily at 60 FPS, and the stutter occurs even in a massively simplified test project. It might not be a bug, so feel free to move this to the greenhorns if needed. 
System
- TouchDesigner 2025.33070
- macOS 15.3.1
- Apple M4 Max
- Built-in Retina display at 60 Hz
- Target FPS: 60
What I have tested so far
- Simplified the network to a basic point-cloud render
- Tested with 800 × 800 points (640,000 vert.)
- Reduced it to 100 × 100 points (10,000 vert. ) the same intermittent stutter remains
- Disabled Adaptive Homing
- Disabled the POP Viewers
- Reduced/disabled operator viewers
- Tested with V-Sync disabled
- Changed the external display from 75 Hz to 60 Hz
- Tested TouchDesigner on the built-in Retina display instead of the external monitor
The normal frame time is only around 3–4 ms. However, using the Performance Monitor with a 40 ms trigger captured a frame that might match the visible stutter.
• Preparing frame for presentation
• Total Window Redraw Time
Has anyone seen similar periodic presentation stalls on Apple Silicon/macOS? Or is it just me using the hardware/software wrong? I mean, you know: Every machine is a smoke machine if you operate it wrong enough.
Is there a recommended way to determine what TouchDesigner is waiting for during preparing frame for presentation? I can provide the simplified .toe file and the complete Performance Monitor logs if helpful.
