Editor freeze/memory leak when having many array values
How to reproduce:
When pasting these values to e.g. a text file, there is no lag at all. Why it behaves differently with DataTable and causes this big freeze? The freeze will appear also when re-opening the saved DataTable, but no freeze when we close it. Why does it need so much RAM to only paste/display the values? This looks like some memory leak...
BTW. I'm not the only one experiencing the major slowdown when having many values in blueprints: https://forums.unrealengine.com/showthread.php?131785-Storing-large-lists-(arrays)-in-blueprints
Yeah, this is expected when dealing with really large numbers of values. The severity of the lag is of course dependent on your hardware but there isn't really a way to avoid it using the workflow you described. But it also seems that you would only need to do it once per Data Table you create.
As everynone explains in that Forum thread, it would be best to use the .csv file method when dealing with this many Member Variables.
