RAM consumption Steam VS Classic version

[SPGMH]

Hi guys, I created this post because I see something strange about the RAM consumption between Steam version and Classic version.

Steam version

Classic version

As you can see, the Classic version use more RAM than Steam version and I don't know why. I don't use any mod and I use default config.

Can you verify that the graphics settings are indeed the same for both versions? In particular the graphics quality?

Yep, I checked and the both version have the same graphics quality.

But deleted the config of steam version and Factorio use 2.4Go like the Classic version.
So I checked the config file and I found what cause this.
Inside the config file, there is a line named "force-opengl". If it set as false, the game will use 2.5Go but if it set on true, it will use 700Mo.

I don't know if this problem is only on Windows (DirectX ?)
