Used in combination with the CPU Usage Limit setting, the RTAS Processors setting lets you
control the way RTAS processing and other Pro Tools tasks are carried out by the system. For
example:
For sessions with large numbers of RTAS plug-ins, you can allocate 2 or more processors to
RTAS processing and set a high CPU Usage Limit.
For sessions with few RTAS plug-ins, you can allocate fewer processors to RTAS and set a low
CPU Usage Limit to leave more CPU resources available for automation accuracy, screen re-
sponse, and video.
Depending on the importance of video and overall screen response, and on the density of
automation being employed, try different combinations of RTAS Processing and CPU Usage
Limit settings to achieve the best results. For example, to improve screen response in a me-
dium-sized session using a moderate number of RTAS plug-ins, try reducing the number of
RTAS plug-ins, but keep the CPU Usage Limit set to its maximum on a single processor sys-
tem.
To set the number of RTAS Processors:
1 Choose Setup > Playback Engine.
2 From the RTAS Processors pop-up menu, select the number of available processors you want
to allocate for RTAS plug-in processing. The number of processors available varies depending
on how many processors are available on your computer:
Select 1 Processor to limit RTAS processing to one CPU in the system.
Select 2 Processors to enable load balancing across two available processors.
On systems running four or more processors, select from the available number of RTAS
processors.
3 Click OK.
