What Nucleo settings affect Nucleos memory usage?
By adjusting the two values in the Nucleo Resource Settings dialog you can increase the memory available to the Nucleo processes. By lowering the number of Nucleo processes the remaining processes can share the memory no longer used by the additional processes. If the free RAM available to other processes increases the calculation Nucleo uses to determine the memory for the Nucleo processes lowers the amount of memory. If Nucleo’s performance level is set to Maximum the amount of memory that After Effects uses isn’t included in the memory calculation that Nucleo performs. There are other considerations to making that change to Nucleo.
