ROG Ally X - Texture settings stuck on Medium

Hi,

I'm playing PoE2 on ROG Ally X, however, the texture settings are stuck to Medium, even though I allocated 8 GB of VRAM in Armoury Crate GPU Settings.

It looks like this is a bug because it does this no matter how much VRAM I am allocating.

Would it be possible to fix this bug?

Thank you very much.
