What does UE4 do when player doesn't have enough RAM?

Hello everyone, I am working on an open-world game, and I am just wondering what the game will do when the graphics require ~8GB RAM, and the player is only playing with 4GB? Will some graphics just not show?

Also another question, if this game requires 8GB to play, what’s a good estimate on how much it will require to edit the actual game world?

If it require more RAM than is available it will crash–like if you are trying to build lighting and you run out of memory then lightmass will crash.
You’re not likely to have that issue with RAM though, for a game it’s more about GPU memory

Generally speaking, running the game requires much less power than working on it. When you are working on a game, you are working with an engine in the background. Once you bake everything, the player won’t be dealing with that. I find they usually need around 1/3 to 1/2 of whatever it took me to build it.

8GB is the bare minimum for working with Unreal Engine. I did it with 4GB for a while, but it was unbearable. You really should have 16GB of ram to be working on a game. Unless you have a crazy high-end game, I find 4GB suitable for play, but that number is dependent on allot of variables.

Yes, I’ve got 16GB, but I guess I’ll have to upgrade to 4x8GB, I’m already using 8GB with just all of my software open and a blank level on UE4 :\
