Key notes

You may be wondering what shared GPU memory Windows 11 means. If you do not know,System reserves half of your RAMfor the video card(s). You can read further into this article to understand all about this matter.

What is Shared GPU memory in Windows 11?

Shared GPU memory in Windows 11 is the total virtual memory that will be used if dedicated video memory runs out. This normally amounts to 50% of the available RAM.

PCs with integrated graphics often employ shared GPU memory. This means that the motherboard houses the display circuits rather than using an expensive graphics card.

How does Shared GPU memory work in Windows 11?

Having gathered from users’ experience on Shared GPU memory, we have outlined the following as how Shared GPU memory works:

Should I decrease or increase shared GPU memory?

Well, it truly depends on your system configuration. However, leaving things the way they originally were would probably be better if you had a dedicated graphics card.

Shared GPU memory might not even be used at all, depending on your particular graphics card and its VRAM capacity.

Tweaking shared GPU memory settings should be strictly avoided. Especially if you have an integrated GPU rather than a discrete one.

Shared memory is essentially RAM. If a GPU has to use the system’s RAM for its computations, it’ll take a performance hit. To prevent these issues and run resource-intensive applications smoothly on your PC, you’ll need a graphics card and RAM that meet their specifications.

To this end, there’s no need for you to adjust anything manually. Although if you feel like adjusting your GPU, you can do so byadjusting video memory settings in your BIOS.

If you have an Intel or AMD APU, you can make the desired changes in the Windows Registry Editor.

Shared GPU memory vs dedicated memory

We explained what shared GPU memory is and how it works, but how is it different from dedicated memory?

It’s simple. The dedicated memory is the VRAM of the graphics card if your computer has one installed. If it has a GPU installed directly on your motherboard, then it will only be able to use shared memory.

And that’s it about shared GPU memory in Windows 11 and how it works. Consequently, running resource-intensive apps on your computer requires a device with enough VRAM, regardless of your GPU orincreased VRAM.
