OpenGL for good FPS

1. Enable Intel Virtualization Technology in the BIOS.
2. Add intel_iommu=on iommu=pt to your kernel parameters (of the host OS).

Native resolution

Assuming your monitor is 1920x1080.

1. Boot into Android debug mode.
2. Mount the boot partition (could be /dev/sda1 or /dev/vda1 or something else) to /mnt (don't worry if /mnt already have files).
3. Use vi to open /mnt/boot/efi/android.cfg.
4. Add set gfxpayload=1920x1080 to the load_theme function, under the set gfxmode command.
5. Change set gfxmode={whatever} to set gfxmode=1920x1080.
6. Save the android.cfg file, unmount /mnt, and then shutdown by poweroff -f.

Small quality of life tweaks

• Wallpaper: Most wallpaper apps for Android assume potrait screen and crop your beautiful 1920x1080 landscape wallpaper, which lead you seeing only a blurred corner in the main screen. Except one app named Slideshow Wallpaper.
