Development build uses far more memory the Shipping.

[mattssonmattsson]

We are running a Unreal application on a platform with very modest amount of RAM (about 640mb free after boot)

Our Shipping build will accommodate about 120mb RAM when running. But our Development build runs out of memory and crashes.

Why does the Development build use so much more RAM? And is there any way to force it to limit its RAM usage?

I found this thread

Limiting UE4 RAM usage

I am currently using UE4 version 4.9.2 and noticing at times the memory usage is off the charts. The machines I am running on have a large amount of ram ( 128gb ) and it seems unreal is happy to eat up half of that or even more. On other machines with only 16gb it often takes up over 13gb of ram. Is there a way to limit ram usage? Is there a known leak in 4.9.2 that would cause 62GB of ram for a scene with ~1400 actors? Any insight would be helpful.

But I cant seem to make this work. I also cant find any official documentation about this setting.
