This page collects information regarding potential optimization of your patches.

Detecting Performance Issues

In order to observe the performance of your patch you have two instruments:

Resolving Performance Issues

  • Learn how to control evaluation of subpatches
  • Hide (Alt+3) patches (not only dock them) to reduce the impact of vvvvs GUI on your CPU
  • Nodes that don't have an input like 'Enable', 'Read', 'Write', ... will see if their input is changed every frame and if so re-perform their task. With large spreadcounts this 'check-for-changed' can be be quite CPU-intesive and often you as a patcher actually know when the change has happened. In those situations use a S+H node before the CPU-intensive operation and only sample its input when you know it has changed.
  • MainLoop (VVVV) has Increase Timinig Precision which is on by default. While causing a smoother framerate in many cases it also causes higher CPU-needs in all cases. You'll have to find find out for your case if you want to change this setting. Here is a good read on the topic Windows Timer Resolution Megawatts wasted.
  • Boost (VVVV) can increase vvvv´s thread priority. In rare cases this may allow you to get the last quantum of performance out of your CPU.
  • Make sure to always use the latest drivers for your graphics card
  • Remove unneeded windows services
