Oh boy! It looks like it's the Vulkan Driver in Godot. Here's a Google Response. "While the GT 620 is an older, entry-level card, some users on the Godot GitHub have reported some performance issues, particularly with Vulkan, suggesting that the card might not have the best Vulkan driver support."
From the Godot site: "Looking on the Nvidia forums, the GT 720M is not Vulkan compatible (Nvidia had plans to support Vulkan on it, but they were dropped 6 years ago)." (That's 9 years now) <- That would be a newer card wouldn't it.
Kind of annoying isn't it. I'm using the latest Godot, version 4.4. So it looks like it's a no-go for the age of that card.
You can find the GPU compatibility here: https://docs.godotengine.org/en/stable/about/system_requirements.html
I think that means any game built in Godot 4.4 onwards might not run on your card . :<
