Hi,
yes, remove the PlaymakerGUI ( you need to turn it off in the settings, else it comes back).
it's important to make sure you get the information of what takes up memory using the profiler, chasing the other way is going to be counter productive.
but yes, indeed that action can be optimized. To check if it the source of your trouble, remove it from the logic and check if the profiler witnesses less memory consumption.
Bye,
Jean
