Re: Battlefield 2042 not using the right GPU

I recently installed the latest BIOS update and still nothing. Apparently there is some "developer mode" for the BIOS that can be accessed by pressing a key combination, which goes like this: 

1. Power off completely.
2. Press the power button.
3. Repeatedly press F2 to enter BIOS.
4. Press the following key sequence 3 times, one key at a time: Fn , R , N.
5. Press F10 and Enter to save and exit.
6. Repeatedly press F2 to enter BIOS, that reveals the advanced settings.

Anyways, this doesn't help at all since it brings up a lot of useless options but no option to modify VRAM.

I've seen videos of people modifying VRAM on older Lenovo laptops, but the new BIOS doesn't allow it.
