Why Dedicated VRAM of 2 GB is not being used by the discrete GPU, only 512 MB being used just like mine integrated GPU does?

I brought this new laptop recently: HP Notebook - 15q-by002ax, It's documented to have a AMD Radeon™ 520 Graphics (2 GB DDR3 dedicated): https://support.hp.com/in-en/document/c05681669.

When i run games or visit task manager, as you can see on the image, it never uses 2 GB VRAM, it only uses 512 MB, which is insufficient to play games.
Practically speaking i only get 512 MB, why is it so? Please help me find the answer.

I updated all software drivers + BIOS and updated directx, graphics drivers and all, and I've searched everywhere, still haven't found no solutions.

Please help me AMD community, i brought this laptop only for that AMD Radeon™ 520 Graphics (2 GB DDR3 dedicated). And if i don't utilize it for what i needed it for, I'll have to quit using this laptop.

Speccy and other applications too, show 2048 MB of memory on details, but on practical use, i feel like i got scammed.



Thanks for reading..

Just because your GPU have 2GB VRAM then it will use all of them when gaming. If you have lower performance in games it could be because of your radeon 520 is weak to begin with. That's why weak GPU with lots of VRAM is useless. You might thinking your games end up being slow because it did not use a lot of VRAM but might forget about your gpu core is slow to begin with before it can reach higher VRAM usage. We see many GPU with lots of VRAM today. Well more never hurts but sometimes all that extra VRAM onboard just becoming marketing ploy by manufacturer.

This is actually true.
You should bought a gaming desktop instead this laptop, or atleast a laptop with MX 150 gpu.
