Default memory usage concerns (200MB-400MB) for empty project

IneedHeelp

Hello, I would like to use Godot (v4.6.beta1.mono on Windows 11) for creating a desktop application, so the project is mostly Control nodes, but first I would like to understand something.

Does anybody know why an exported empty project, empty scene (on Windows) uses ₂₀₀+ MB of RAM when using the d3d12 driver and ₄₀₀ MB of ram when using the vulkan driver?

In the Debug>Monitors tab for Memory it says it uses ₆₅ MiB, so I’m assuming the rest of ₁₄₀ MB (d3d12) / ₃₄₀ MB (vulkan) is used by the engine itself.

Is there any way to lower the default memory usage for an exported application that’s used only for the 2D/UI side of Godot?

How do you measure that and are you sure that doesn't include VRAM?

I also have a 2D UI non-game app and for a quick check I just started the latest debug export and the task manager says 104 MB in the "Memory" column on the Processes tab. I am using the Compatibility renderer.

You could try reporting this on the issue tracker as "Godot 4.6 Mono Windows export excessive RAM":

Toxe Thanks for the reply. I'm using both Task Manager and Process Explorer, I'm sure it doesn't include VRAM. I'm not getting much better results with Compatibility renderer, but I guess it's fine when comparing to other memory hungry applications such as browsers, Discord, Steam, etc.;
