Setting up your system
The VST Performance Window
Optimizing processor scheduling (Windows only)
To get the lowest possible latencies when using ASIO under Windows (on a single-
CPU system), the “system performance” has to be optimized for background tasks:
1. Open the Control Panel and select the System settings.
2. On the left, select the “Advanced system settings” option.
The System Properties dialog opens.
3. Select the Advanced tab and click the “Settings…” button in the Performance
section.
The Performance Options dialog opens.
4. Select the Advanced tab and activate the “Adjust for best performance of:
Background services” option.
5. Click OK to close the dialogs.
Multi processing
On the VST Audio System page you will find the “Advanced options” section. Here
you find advanced settings for the VST Engine, including a Multi Processing option.
When this is activated and there is more than one CPU in your system, the processing
load is distributed evenly to all available CPUs, allowing Cubase to make full use of
the combined power of the multiple processors.
The VST Performance Window
The VST Performance window shows the audio processing load and the hard disk
transfer rate. This allows you to verify that you do not run into performance problems
when adding effects or plug-ins, for example.
To open the VST Performance window, open the Devices menu and select “VST
Performance”.
The “Average Load” indicator shows how much of the available CPU power is
used for audio processing.
The “Real-time Peak” indicator shows the processing load in the realtime path of
the audio engine.
The higher this value, the higher the risk that drop outs might occur.
The Overload indicator to the right indicates overloads of the average or real-time
indicator.
If it lights up, try decreasing the number of EQ modules, active effects, and audio
channels that play back simultaneously. You can also activate the ASIO-Guard,
see
“The ASIO-Guard Option” on page 25.
The disk indicator shows the hard disk transfer load.
