Lowering default 1080p resolution speeds up emulation a lot, especially on RPi which is always too slow. Good idea for all systems too. Here’s what you have to do.
Run Batocera and login with SSH
issue: mount -o remount,rw /boot
Edit /boot/batocera-boot.conf and make sure you add a line:
es.resolution=max-1280×720
Edit /boot/commandline.txt and at the end of first line:
video=1280×720@60
Reboot.
That’s all, now your Raspberry runs all the games and ES a lot faster without noticeable degradation of image!
Maybe it’s a time to think about making 720p default for all low power systems?
