nDisplay memory usage issue

I’m running into some weird issue (bug?) while using nDisplay on a single computer with 2 graphic cards. This is a simple setup with 1 master and 1 node, each worrking on a separate card and outputing to 1 fullHD screen. When I run the project normally it uses around 1go of RAM and doesnt move (1 level, nothing much happening except a niagara GPU system), but when I use nDisplay it starts using more and more memory until it crashes at 32gb after a few minutes.
Is this happening because I’m on a single computer and I didn’t setup something properly ? Works fine in the template level.
