Out of Video Memory (Ram Cause)

This thread was marked as resolved from inactivity, but since then useful information was added.

It relates to the “Out Of Video Memory” dialog, happening when the Ram (and Pagefile) run out. It seems to increase slowly for little reason. The only fix i know, is to increase the pagefile on an SSD to give you more time before it runs out. After pressing Okay on the dialog, the editor completely closes, without even showing the usual Crash Report Menu.

Is there a different way to prevent this? It still happens in the latest UE4 version. I feel like my Ram and Pagefile should not be completely full at 16 + 70GB when only running the editor.
