Realtime
Shows the average load of all audio realtime processes.
ASIO-Guard
Shows the average load of processes that can be preprocessed.
NOTE
Preprocessing only takes place if you activate Activate ASIO-Guard on the Audio
System page of the Studio Setup dialog.
Peak
Shows the processing load in the real-time path of the audio engine. The higher this
value, the higher the risk that dropouts occur.
Processing Overload
The overload indicator on the top right indicates dropouts. These occur if the
processing load exceeds 100 % or if the audio engine is restarted due to the
internal detection of too high processing delay. This might for example occur if the
preprocessing buffer runs empty due to too high real-time load.
If it lights up, decrease the number of EQ modules, active effects, and audio channels
that play back simultaneously. You can also activate the ASIO-Guard.
Disk Cache
Shows the hard disk transfer load.
Disk Cache Overload
The overload indicator to the right of the disk indicator lights up if the hard disk does
not supply data fast enough.
If it lights up, use Disable Selected Tracks to reduce the number of tracks playing
back. If this does not help, you need a faster hard disk. To reset the overload indicator,
click its display. In the
Audio Performance category of the Key Commands you can
also assign a key command for this.
NOTE
You can show a simple view of the performance meter on the Transport panel and on the
Project window toolbar. These meters only feature the average and the disk indicator.

ASIO-Guard
The ASIO-Guard allows you to shift as much processing as possible from the ASIO real time path
to the ASIO-Guard processing path. This results in a more stable system.
The ASIO-Guard allows you to preprocess all channels as well as VST instruments that do not
need to be calculated in real time. This leads to fewer dropouts, the ability to process more tracks
or plug-ins, and the ability to use smaller buffer sizes.
