Caching Limits
The Caching Limits include options for Fusion’s RAM cache operation. Here, you can determine
how much RAM is allocated to the RAM cache for playing back comps in the viewer.
 Limit Caching To: This slider is used to set the percentage of available memory used
for the interactive tool cache. Available memory refers to the amount of memory
installed in the computer.
When the interactive cache reaches the limit defined in this setting, it starts to remove
lower priority frames in the cache to clear space for new frames.
 Automatically Adjust In Low Memory Situations: This checkbox will set the caching to
adjust when memory is low. The console will display any cache purges.
 Leave At Least X MBytes: This setting is used to set the hard limit for memory usage.
No matter what the setting of the Cache Limit, this setting determines the amount of
physical memory available for use by other applications. Normally, this value should not
be smaller than 25 MBytes.
Interactive Render
The Interactive Render option allows you to optimize Fusion’s processing based on the amount
of RAM you have installed in your system.
 Simultaneous Branching: When checked, more than one tool will be processed at the
same time. Disable this checkbox if you are running out of memory frequently.
