ASUS made it easy to increase the ROG Ally VRAM allocation. To give you more control over the Ally, they allow you to customize how much of the memory is reserved as VRAM.
How To Increase The ROG Ally VRAM Allocation
Open up Armoury Crate and go to the Settings tab.
Click Operating Mode
Click GPU Settings and switch change the VRAM. You will have to reboot the Ally for the change to take effect.
This can be helpful in a few scenarios:
You want to increase VRAM to use higher-resolution textures in modern games like The Last of Us.
You want to increase VRAM to reduce stuttering in certain VRAM-heavy games like Call of Duty: Modern Warfare II.
You’re getting an error on launch that a game will not start because not enough VRAM is present, like in Assassin’s Creed Valhalla or Rainbow Six: Extraction.
You want to lower the VRAM allocation so you have more system memory for other programs running in the background.
For example, when trying to launch some games you may receive an error that says “Your system specs do not seem to match the minimum requirements for the game. Please check your hardware and GPU settings” and “Available graphic memory detected is below” the required amount. Raising the Ally’s VRAM reserve will allow the game to launch as normal.
