@Cloyn Greetings from the HP Community!

Here's everything you need to know about reducing the Video Memory on the device: 
(Similar information has been shared on this same thread: click here to verify)

That said, before trying out the methods to increase the VRAM, you need first to check how much dedicated video memory your graphics card has in Windows 10.

Go to Start menu and click  Settings. Navigate to System and click Display on the left sidebar of the System Settings.

Scroll down the Display menu and click on the option Display adapter properties at the bottom of the box.

In a new pop up window, you will see the adapter type used on your system and other graphics information in the Adapter tab. Check the total amount of allocated space for the dedicated video RAM under Adapter information

Increase the dedicated video memory on your graphics card from BIOS

This is the recommended method to reallocate the memory of VRAM allocation. However, this doesn’t work for all the motherboards, and you may not be allowed to reallocate memory on your PC all by yourself. Still, you can try to change the BIOS settings and check if you have enough privilege to change the amount of dedicated video RAM on your PC.

Restart your PC and press the BIOS key – F2, F5, F8 or Del key repeatedly during the bootup.

In the BIOS menu, go to Advanced Features or similar option.

Now click on video/ Graphics settings or VGA Share Memory Size. If you don’t find these options, look for a category with a similar option.

Adjust the option that best suits for your task. The default memory allocated to the GPU is usually 128MB. You can scale up the preallocated VRAM to 256MB or 512 MB.

Save the changes and restart your system.

Increase the dedicated video memory on your graphics card using Registry Editor

Depending on the applications you run, the system automatically adjusts the amount of video RAM it needs. And thus the adapted information showing the amount of VRAM used on your graphics card is not always genuine. However, to run some applications, you will need more VRAM. In such a case, you can simply replica the amount of VRAM to substitute for the amount of VRAM your system needs to run the application. You are not increasing the value for real, but you scale up the amount of VRAM to a value to serve as a substitute for the memory requirements to start the game or an application.

Follow the below steps to reallocate RAM as VRAM for integrated Intel graphics cards.

Open Run and type regedit. Navigate to the following path:

HKEY_LOCAL_MACHINE\Software\Intel

Right-click on Intel folder. Choose New and click on Key. Name the key as GMM.

Select the new GMM folder on the left sidebar.

Right click on the right side of the Window and click on New from the drop-down menu.

Choose the Dword (32-bit ) and name it as DedicatedSegmentSize.

Double click on the DedicatedSegmentSize and click on the radio button with option Decimal to set the base to Decimal.

Enter the number of megabytes of RAM you want to allocate as VRAM in value data. Make sure you type a number within the range from 0 to 512.

Save to apply the changes and Restart the system.
