Chapter 4: Configuring Your Pro Tools System 29
CPU Usage Limit
The CPU Usage Limit controls the percentage of CPU resources allocated to Pro Tools host pro-
cessing tasks. Used in combination with the RTAS Processors setting, the CPU Usage Limit set-
ting lets you control the way Pro Tools tasks are carried out by the system.
Lower CPU Usage Limit settings limit the effect of Pro Tools processing on other CPU-inten-
sive tasks, such as screen redraws, and are useful when you are experiencing slow system re-
sponse, or when running other applications at the same time as Pro Tools.
Higher CPU Usage Limit settings allocate more processing power to Pro Tools, and are useful
for playing back large sessions or using more real-time plug-ins.
The maximum available CPU Usage Limit depends on the number of processors in your com-
puter and on the number of processors you specify for RTAS processing. This value can range
from 85 percent for single-processor computers to 99 percent for multi-processor computers.
To change the CPU Usage Limit:
1 Choose Setup > Playback Engine.
2 From the CPU Usage Limit pop-up menu, select the percentage of CPU processing you want
to allocate to Pro Tools.
3 Click OK.
Increasing the CPU Usage Limit may slow down screen response on slower computers.
