Prompt: How to change VRAM on Steam Deck to 2GB or 4GB?
Response:
To change the VRAM allocation on your Steam Deck, follow these steps:
Enter BIOS Menu: Power off the Steam Deck, hold the Volume Up button, and press Power until you hear a chime.
Navigate BIOS: Use the touchscreen or volume buttons to access the Advanced section.
Adjust VRAM: Look for the UMA Frame Buffer Size option, which lets you choose the VRAM amount (1GB, 2GB, 4GB). Select either 2GB or 4GB.
Save and Exit: Go to the Save & Exit section, confirm the changes, and reboot the system.
Verify Changes: After restarting, check the VRAM allocation through a system monitoring tool or game settings.
This adjustment can enhance performance in certain games but reduces available system RAM, so choose accordingly.
